Bo chain “financial CBBC Apocalypse” Yang Linke: CBBC’s history repeats itself

After 2018 10 launched the high-end video chat show “face” gangster interview bitcoin renowned investor Li Xiaolai, Bo chain finance and strategic Associated Media to 36 krypton “Odaily|” Daily Planet launched the depth of interactive online interview column — “CBBC Apocalypse”, aimed at through and across the CBBC’s mind dialogue. With “elegant” through the coin circle long bear.

Fifth guests:

Yang Linke, founder of bitcoin China, Ledong capital founder

Host:

Liu Sha, [Bo] content partners, financial chain chain technology founder

The following is the interview record:

Bo Chain Finance: you are the first person Chinese bitcoin, will share how you come into contact with bitcoin? And that is how to understand bitcoin this new species? Of course, the bitcoin circle of those things and fun?

Yang Linke: (Chinese bitcoin) the first person is Huang Xiaoyu, he took me to, I am very grateful to him. I am Chinese bitcoin second.

At that time, few people know bitcoin in China, only a few geeks know. We first do the exchange (bitcoin China) is also very cautious, not registered company. (until 2013) the company began.

Second thank my another former partner Li Qiyuan, he eventually led bitcoin Chinese success.

(Huang Xiaoyu and Li Qiyuan) they are good partners, so we choose a partner when the character is very important.

Now they are both retired, I still choose to continue the fight!

 

From left to right are: Yanglinke Huang Xiaoyu and Li Qiyuan

Bo Chain Finance: in 2011, you and Huang Xiaoyu founded the earliest China bitcoin exchange, then you and Huang Xiaoyu are going to think? Why do think this is a worthwhile to devote business?

Yang Linke: at that time did not think so much, think it is a good business, open dry.

Sometimes when you are a good thing, think too much is not necessarily a good thing, it is important to start again in the process of adjustment.

Bo Chain Finance: compared to this wave of people to talk money, 2011 to 2013, China bitcoin circle is very small, you and your team to do anything worth mentioning?

Yang Linke: I remember (Qinghai) after the Yushu earthquake, we and the one Foundation launched bitcoin donations, the time that bitcoin really can be used in some places, I feel very good.

 

2013 in the garage coffee “bitcoin China” Beijing Railway Station

There is our treasure sponsored two bitcoin Chinese, then ran dozens of city, have certain significance for the popularization of the bitcoin.

In 2013 we made a bitcoin payment products, also received a number of businesses, because the year 12.5 files and finally stopped, so in the end can only be used for payment industry media advertising.

Bo Chain Finance: bitcoin has created too much wealth myth, such as rumored “middle-aged Uncle Lee to rely on bitcoin currency China circle’s richest man, you have much wealth in bitcoin above accumulation?

Yang Linke: Tun some bitcoin, EOS, wave and other various coins.

This industry is still in the early (people), most should not how the money.

Of course, in the bear market can persist are believers, “left for the king”.

Bo Chain Finance: in 2013, bitcoin Chinese has just got the light $5 million equity financing not long, just have a national policy regulation, then bitcoin China and how you deal with and spend?

Yang Linke: when the melt end capital have survived, including OKCoin and fire coins.

At that time the market is still very small, is now 10 times the time.

2014 and 2015 are all trying to live OKCoin, Internet banking, currency, money do fire, we do mine pool.

No matter how to live, hope alive.

Bo Chain Finance: we know that in 2014 experienced a slump in 2015, why you will “get off”? At that time, have a kind of mentality?

Yang Linke: when you leave and come back a lot of things are not the same, many people have left, many also finally came back, will this wave. Don’t get off so easily!

If you are optimistic about the industry, is determined to go on.

Bo Chain Finance: the first “get off”, you have to do what? It was prepared to go back, still on the coin ring reluctant to part?

Yang Linke: while leaving the industry for a long time, but still bitcoin China shareholders and directors, but it is still in the concern of the industry trends, I C O the initial outbreak, also voted several projects, the performance is very good.

Bo Chain Finance: we all know that a wave of currency circle earliest bitcoin exchange — China, OKCoin, fire currency, and the rise of the past year’s money, how to evaluate the other 3 business style, if the next time you see Li Lin, Xu star and Zhao Changpeng, you most want to say what to them?

Yang Linke: they each have their own light, we are all good friends, now may have their own stalls (things), long time no see, looking forward to meet again.

Bo Chain Finance: over the past year, the most satisfied with your personal and Ledong capital investment have? What are the missing investment opportunities?

Yang Linke: in 2018 more than 95% of the Token Fund are losses, we are glad that the investment is relatively small, so it’s okay.

Bo Chain Finance: listen to bitcoin China insider, many long before follow you, bitcoin investment also have a lot of accumulation of wealth, this time you return, they are you to call back, you are a nostalgic feeling of the people?

Yang Linke: in 2017, together with my friends really make a lot of. Including a lot of people buy early coins in bitcoin China are good, I think this is the biggest value of bitcoin Chinese, everyone mutual achievement is fun.

BTCC also sold many of his colleagues to make before a lot of money. So, welcome to join the bitcoin Chinese.

Bo Chain Finance: currency circle today many couples are very pessimistic, this time with the 2015 similar?

Yang Linke: history always repeats itself!

This market has been a long cattle bear short, do not dream of bull market will be very long.

Bo Chain Finance: over the past 2 years, although you also in the coin circle, but compared with Zhao Changpeng, Li Lin and Xu Mingxing et al., does not seem to you in the spotlight of the time, if you give 90, even after 95 currency circle practitioners to introduce yourself, you want to how to introduce yourself, and you want them to you what kind of label?

Yang Linke: This is not important, (brief introduction: I am a bitcoin China Yang lynco).

Bo Chain Finance: we have this column called “cow bear Apocalypse”, the starting point is hope interviews can lead you through the long bear market, the new currency of your circle through the winter capital what advice?

Yang Linke: keep on keeping on. (hold on, try not to get off.)

Bo Chain Finance: why choose to return at this time? This does not seem to be a better time? (the bear market bleak, low popularity.)

Yang Linke: I have been in 2018, we are also in the work. Bear more work, more harvest bull.

I’m pretty sure the blockchain will become better and better, the global stock market capitalisation of 80 trillion (US $), block chain 1000 billion (US $). When all the assets are Token, you want to have much chance.

Bo Chain Finance: according to relevant national laws and regulations, the current bitcoin China compliance plate is the block chain technology related business. So, in addition to the investment of ZG exchange, in the winter, you will be how to layout, and has a kind of logic behind?

Yang Linke: bitcoin is like 2G, Ethernet square is 3G, EOS is 4G, with the time go on, there must be 5G.

We (bitcoin China) or focus on technology exchange.

Bo Chain Finance: the next exchange competition pattern will be changed? In your opinion, what is the biggest digital currency exchange moat?

Yang Linke: the exchange of core competitiveness is still the most safe, most exchanges will die.

Bo Chain Finance: in the winter, we found a lot of people to leave, but there are many like you, “the old man” in return, what do you think about this phenomenon?

Yang Linke: everyone’s cognition is different, so different, it is important to have no understand.

Bo: as one of the earliest financial chain bitcoin investors and industry participants, after other digital currency bitcoin has experienced 2 wave bull bear market, whether the current price can be considered hunters?

Yang Linke: have to buy at the bottom.

Bo Chain Finance: if three people let you Liebite coins and block chain favorite, you will train who, why?

Yang Linke: Huang Xiaoyu Li Qiyuan Li Lin.

Huang Xiaoyu and Li Qiyuan are fighting alongside partner, Li Lin, play pattern.

Bo Chain Finance: if you let you recommend three guests to attend Bo “financial chain Niuxiong Apocalypse” column, who would you recommend? Why?

Yang Linke: God fish star Li Lin xu.

Thank the support more media on this column

Brush brush volume in prison, South Korea bitcoin exchange Komid CEO was sentenced to 3 years in prison

According to South Korean media reports, South Korea in January 18th, the Komid two bit encryption currency exchange platform for company executives scalping (fake transactions) and sentenced to imprisonment.

The chief executive officer surnamed Cui (CEO) was sentenced to three years in prison, while another does not specify the duties of the company executives allegedly because of fraud, corruption and misconduct and was sentenced to two years in prison.

According to the submitted in connection with the report, Komid transactions brush 5 million transactions, forged the transaction amount of approximately $45 million, which makes the exchange trading volume on the surface is very attractive to customers.

In the past year, we have seen many industries and the exchange was broke and the amount of brush news. As competition intensifies, more and more exchange attempts to brush the way, to win more customers, which has become a very serious problem which often exists in industry.

Just last month, another from South Korea’s encryption currency exchange Bithumb also face the same charges. Encrypted Currency Exchange Statistics website CER claimed that Bithumb exchange forged trading volume, although Bithumb denied the trading fraud, but now what about this problem become more serious, still worthy of our attention.

In fact, according to the research data in December last year the blockchain Institute transparency disclosure shows that there are many problems of the amount of brush exchanges in the industry, and the situation is very serious.

Because many of the top encryption currency exchange transactions are forged, therefore, a thorough investigation suggested that the user system in the choice of exchange before, avoid to be deceived.

Why PoS can avoid the 51% attack than PoW?

Note: recently 51% ETC attacks, PoW security issues are hot, etheric Fang founder V God said that from PoW to PoS is the right choice. The daily planet Odaily invited Shanghai Jiao Tong University associate professor Fan Lei, why he thought that PoS may be a better choice for our analysis.

This paper starts from the Odaily daily planet, author Fan Lei, Shanghai Jiao Tong University School of cyberspace and associate professor Fractal Platform CTO, the security and development direction of the block chain consensus protocol of original title “.

 Why PoS can avoid 51% attacks than PoW?

Recently, in the crypto currency appeared in the field of an important attack. The etheric Fang classic (ETC) encountered 51% force double attack in January 8th, according to the calculation of different caliber, the attack caused tens of millions of dollars of losses. This is the first successful attacker according to the top of the mainstream password monetary 51% attack, relative to the calculation of the loss of reality, deep security problems facing money behind should pay more attention to the encryption.

What is the 1. 51% attack

At present, bitcoin digital currency (Bitcoin) as the representative of the majority of passwords based on the proof of work (Proof of Work, PoW) of the consensus protocol, in the proof of work miners by calculating the new block makes the growing chain block. Because of the block chain is a decentralized system, anyone can attempt to generate a new block from any location. If the attacker have less computational resources, the attacker generated new growth rate will slow to open branch block chain growth rate, it will not be accepted by the formation of honest users long branch. But if the attacker mastered the computing resources more than honest users, while the growth rate will be a new bifurcation attacker generated faster than the growth rate of the open chain block, block chain branch he is easy to form a new longer to replace the longest open chain block. Specific processes see Figure 1 and figure 2.

 Why PoS can avoid the 51% attack than PoW?

Figure 1. the attacker is less

 Why PoS can avoid 51% attacks than PoW?

Figure 2. is the dominant force of the attacker

The computing resources dominant attackers, simple mathematical description is that the attacker mastered the calculation capacity of more than 51%, which is the origin of 51% is the name of the attack force. When the attacker mastered the computing resources of more than 51%, his attacks will be successful. In fact, when computing resources, the attacker mastered enough proportion such as 40%, if the 6 blocks as he can confirm the length, with relatively large probability of the successful implementation of the bifurcation of the attack.

Once the successful implementation of 51% force attack, block chain will switch the longest chain, the consequences have been confirmed the transaction data may be erased in the area. If the attack is intentionally, the attacker can withdraw has been confirmed in high transaction data blocks, and then the digital currency can be used again. This attack is what we often say that the double attack, apparently this attack behavior has seriously damaged the password security and credibility of digital currency.

2. why can successfully attack

Different from the general network security attacks, 51% force attack is already known as the method of attack, the attack behavior and process the attacker does not have any new ideas.

Generally speaking, PoW is the overall password monetary system based on the stronger, which control 51% of the calculated force required higher cost. Because most of the PoW algorithm has the same core computing structure, computing power can be easily in a different password switch directly or even a currency, in accordance with the time is convenient rental resources. Crypto51 website (https://www.crypto51.app/) statistics for different digital currency for 1 hours to 51% attack costs (excluding block reward) and can borrow from NiceHash is the ratio of force. For ETC, 1 hours 51% attacks only need to spend $5116, and the loan to 80% of the calculated force from the NiceHash (continuous change, the data to the site can view real-time data), the possibility of attacks can not be ignored.

Another factor that can not be ignored is that the PoW algorithm needs a lot of energy driven mining operations. When the password money market value less than mining income, driven by the interests of the machine will stop off. This will cause a sharp decline in the resources, which will make 51% attack more easily. The ETC implementation of the 51% attack is the use of this opportunity. But for the emergence of new PoW based password money, because the whole network is low, so the attack cost lower.

The possibility of ETH suffered 51% attacks to less than ETC, because ETH and ETC use the same ETH mining algorithm, but the whole network is about 20 times ETC. Nevertheless, the founder of Vitalik Ethereum in the wake of the attacks still sound said the incident proved that he was ready to shift from PoW PoS’s decision is correct.

3. PoW block chain based on still safe

There is no doubt that in the past 10 years, the encrypted digital currency bitcoin represented a huge success, its security has been testing the real operation of the network. Not only that, cryptographers also theoretically proved the safety chain based on block PoW. People believe that mathematics is the foundation of block chain security, which is also called the In Math We Trust. But in recent years the development of technology and research show that based on the PoW block chain is also a safety hazard.

1) is the stress concentration problem

In fact, in the bitcoin digital currency system password, because the super pool exists, people of long-standing concerns focus. The ore mine pool and large pool of stakeholders which might be close to or even exceed 51% is. We cannot say that these large hashrate group will launch 51% system to calculate force attack, but at least they have the ability to launch such attacks.

2) is a black swan hidden

In the current technical conditions, is the password digital currency depends on the hardware operation speed and energy supply. There is always a danger is that when there is the leaping progress, the security of the system may face a major threat. As a result of replacement of the invention or chip process of fast algorithm, a new computing resources may be overwhelmingly more than the original resources, in this case the security system will be completely destroyed.

The above analysis shows that the PoW block chain security is not built on the basis of mathematics, mathematics is only the adhesive between the physical resource and the blockchain. Once the security assumptions of physical resources is not established, the safety block chain system are under threat.

From the system level, the PoW block chain is selected to rely on competition is based on block producer, accounting people. Is to block chain ecosystem itself belongs to external resources, a user can rent is the size of its holdings of chain assets / interests are not necessarily related, and counting the force that is rental site use right transfer. For example, mine owners or machine manufacturers own hashrate owners’interests and main chain security binding, but is not the rental. How much stress is the only factor to attack, if the selfish mining strategy can not reach to the current public chain attack force of 51%, produced honeysuckle.

Therefore, in the PoW block chain system, the value system of foreign investment by an attacker can compute resources threaten existing digital currency. Due to the existing PoW algorithm, a high degree of homogeneity, a large amount of computing resources in the system can be user completely unaware of the case injected in this process, any user can even do not have any involved in the ecological system. Use “body” in a sentence: “I destroy you, has nothing to do with you.”

4. we have no better choice

In recent years, more and more block chain system and distributed consensus protocol is presented. One important direction is the interests based on the consensus (Proof of Stake, PoS).

PoS originally proposed is mainly to solve the existing problems of energy consumption PoW. PoS and PoW are essentially the same, in order to participate in the block chain network node randomly selected a node to account. The word “random” appears to be simple, that is fair, unpredictable, not by the malicious nodes, but in a decentralized network is very difficult, because there is a God to throw the dice. The principle of random PoW is owned is more likely to become more functional, the principle of random PoS is more stake have more likely to become accounting people, both look very similar, just for the election of the “certificate”, but according to their design and attack their faces are very different.

PoS relies on stake to select accounting people, to participate in the election of people who have stake are recorded in the block chain, a proportion of stake – a user holds the stake block chain accounted for the proportion of the total number of stake. For the PoS to 51% attacks, need to hold a chain of 51% stake, and stake obtained only from the existing user to buy investment in production system. It launched 51% attacks on the PoS system cost is equal to the cost from the market to buy stake.

In the case of ETC, the total issued ETC is 107514088 ETC, if the consensus algorithm is PoS, the 51% attack needs to hold ETC on the 53747044, equivalent to the market value of about $229542578, while in the case of PoW by renting only about $5000 of work force. Other digital currency funds required for PoS 51% attacks against PoW and contrast 1 hours 51% attack cost as shown in the following table (data from Crypto51https://www.crypto51.app/ data, real time changes, the following data from the time of writing). Hold stake and more people in the legal chain more inclined to maintain the chain, if the stake transfer leased to the attacker, the risk is much greater than the rent is, so the attacker is difficult to get enough stake through the rent. So the 51% attacks, PoS has more advantages than PoW. This is also an important reason for the evolution of ETH to PoS consensus.

 Why PoS can avoid the 51% attack than PoW?

In short, compared to PoW, PoS there are two biggest advantages, one is to avoid the waste of energy, but also reduces the cost of nodes participating in the consensus, the other one is that it can produce 51% attack threshold, in the current calculation of stress concentration under the situation of PoS relative to PoW to more security. But, as some of the whole network is smaller emerging digital currency like PoS digital currency consensus algorithm in the initial phases of the 51% are also vulnerable to attack, because the initial chain total stake small, 51% attack the funds needed for the corresponding is relatively small, so the need to strengthen security during the initial startup good coping strategies, prepared in advance.

Worry and deal with the 5. PoS consensus protocol

Compared to PoW has been more than a block chain project has been successfully applied in the PoS protocol, consensus has not been large-scale application, so many people are on the PoS consensus protocol concerns. In view of our attack and the weakness of PoS may exist are analyzed.

1) PoS is a centralized system

In the study of PoS algorithm at the beginning, many researchers naturally inspired by distributed computing theory and cryptography. The Byzantine fault tolerance protocol (BFT) is a classical algorithm for consensus in a distributed environment, so PoS consensus algorithm has been proposed for most BFT can be seen as a kind of deformation form. The advantages of BFT algorithm in the ideal network environment to confirm the time delay is short, but it is because of the high communication complexity limits the number of nodes participating in the consensus, so the public in the world in the chain can not be used directly. In EOS (DPoS), Algorand and other systems, by selecting the representative part of achieving consensus implementation of Byzantine agreement, so to bring PoS is a subjective impression of centralized protocol. In real time, the present study has also made a similar PoW competitive PoS agreement, do not have to worry about is the centralized PoS system.

2) PoS new chain cold start is not safe

One idea is that due to the PoS system of consensus node is determined by Token, and the system must have the prior distribution of token before the cold start, so the control of the PoS system belongs to a small amount of these early participants, in order to obtain excess interest and monopolist may even destroy the whole evil system to achieve double attack. In practice, these concerns are not exist, the reasons are as follows:

A) the current ecological development block chain has been more mature, the new block chain backbone before the line often after several rounds of fund-raising activities, so even the founding team could not control the excessive Token share. And the rational team would not be too much to share control, only Token system is safe enough to disperse.

B) in the PoS system, Token has the rights of fully reflected in the value of Token in. Which have greater power to maintain the safety of the system, and therefore more difficult to participate in malicious action. But in the PoW system, the attacker attacks can obtain short-term interests will be transferred to other investment force hardware block chain system, so take the possibility of malicious behavior is higher.

C) in the start-up phase of new block chain, if using PoW protocol, external computing resources can be poured into the uncontrolled system. At this time due to the whole system’s power is not high, the attacker uses fewer resources to complete the attack, so the cold start phase of PoW block chain more secure. In fact, in addition to bitcoin, Ethernet square has gathered PoW block chain is the new force, the block chain are facing this problem. The first stage is to bring the BCH bifurcation competition reflects the risk of new chain starting, in order to avoid being attacked is often the center of the pool to maintain the safety of early, so concentrate on more than PoS.

3) PoS concentration of wealth is serious

In the preceding discussion, we have analyzed the start-up phase in the PoS block chain often has achieved the initial allocation of Token. The initial Token growth in the subsequent block chain process will indeed bring further investment returns, there is concern that the rich get richer by centralization of wealth. To solve this problem, we analyzed as follows:

A) in any economic system will be a wealth concentration phenomenon in the PoS system and no more serious. Economic research has shown that even in the most equitable economic system will also appear in the phenomenon of concentration of wealth. Reflect the fortune 28 distribution phenomenon we often say that the formal wealth concentration. The initial Token distribution PoS system than most equity allocation giant listed companies in the initial stage of more dispersed and transparent.

As long as b) provides a fair and transparent trading environment, wealth centralization phenomenon does not magnify without fear. If Token can in the two free market circulation, Token will naturally get a fair market price valuation. If you get enough benefits to attract, the original investors will sell; if the good of prospects, later investors are rational purchase. So don’t worry about that later do not buy, or wealth fully centralized.

In fact, due to the participation of PoW system needs a large number of mining investment of hardware and power input, scattered participants from a cost point of view is far less than the large pool, when the price of currency market volatility is often the small scale miners first exit, so centralized wealth in the PoW system and the force will be more obvious.

4) PoS will be attacked by Nothing-at-Stake

Nothing-at-Stake is in the PoS system, the attempt to produce a block does not consume a large amount of hardware resources, so the attacker can not abide by the agreement and has produced a new attempt to block behind different blocks. This gives us a clear intuition, PoS system is more prone to bifurcation. But the design of a good PoS system can resist Nothing attack at Stake.

An essay written in [1] we put forward a new PoS iChing protocol, this protocol is competitive consensus protocols like PoW. The Greedy Attack (an attack strategy based on Nothing-at-Stake) is analyzed, results show that the attacker greedily try to scale at any position of the chain does allow an attacker to profit, but the profit is not infinite. If an attacker and its performance in the honest nodes hold the same proportion of stake, e times generated by the attacker chain growth rate will reach the most honest chain (E is a mathematical constant, about 2.71828), so PoS can tolerate malicious stake ratio does not exceed 30% (see the calculation process). In view of this situation, this paper gives a new strategy, in the strategy of encouraging moderate greedy honest nodes, can tolerate malicious stake ratio can reach more than 43%. So Nothing at Stake is not an insurmountable attack.

5) PoS will be attacked by Long-Range

Long-Range attack refers to the attacker through the long-term accumulation of the attack on the PoS system means that the concrete forms may vary. The most direct Long-Range attacker to collect or purchase of a large number of stake accounts available at some time in the past, which began to diverge from the earlier point in time. This paper presents a [2] belonging to the Long-Range attack strategy, called Stake-Bleeding attack. In this attack, the attacker through the branch mining long time secret, accumulated enough reward after token launched the attack bifurcation.

The Long-Range attacks we made a classified summary of overall Long-Range attack takes a long time to implement the preparation and operation. According to the characteristics of Long-Range can adopt corresponding technical means to avoid or eliminate, including setting up a regular detection point (check points). In fact, in order to improve the blockchain verification speed, detection technology in PoW block chain is often adopted. Therefore, Long-Range attacks on the real PoS block chain system does not have a serious threat.

The characteristics of the block chain 6. next generation should meet

In order to support more practical application of floor, block chain in addition to the basic requirements to meet the characteristics of safety, to the center, but also solve the throughput rate is not high, confirm the delays.

Low throughput is mainly due to the traditional structure of block chain and network transmission delays, so recently proposed DAG structure, transaction mode, transaction processing chip package are studied in order to improve the throughput and make the chain block.

Confirm when the extension is competitive blockchain consensus algorithm has problems to solve this problem can be improved by rapid confirmation in the upper protocol stack.

We believe that the next generation must meet the following characteristics of block chain can really support the safety, efficient and flexible landing:

1) PoS algorithm based on consensus, to avoid security dependence on external resources, to eliminate the threat of attack from the outside of the system.

2) adhere to the center of the design, will be entrusted to avoid system consensus right for a small node, otherwise it will fall back into existing center system.

3) the design of distributed data compact, avoid transaction data in broadcasting and storage network to support the application of high throughput.

4) high speed algorithm to achieve fast superposition confirmation, confirmation of the normal business, to support the application of the scene in real time.

Ethernet square core developers in February 27th to determine the hard bifurcation of Constantinople

Beijing time on January 18th night at 22:00, including Vitalik Buterin, Martin Holste Swende, Afri Schoedon and Peter Szilagyi, Ethernet square core developers conference call on matters discussed hard bifurcation of constantinople. According to the P ter Szil Ethernet square developers, gyi said, Constantinople hard forking will be delayed six weeks in 7280000th blocks, the specific time for the Beijing time 16:56 on February 27th; it is also worth noting that this will be the “double bifurcation bifurcation”. Peter Szilagyi proposed “double Ethernet Fang bifurcation”: first established in Constantinople bifurcation, then carries on the revision, add a disable, remove the problem EIP – 1283 proposals.

Bitcoin prices fell to $3550, the day fell more than 4%

Today, the market value of the top 20 encryption currency appeared to significant decline. According to the technical data block chain network, bitcoin prices again close to $3550.

As of press time, bitcoin day fell more than 4%, the transaction price of about $3587. From the weekly chart, the current price is lower than last Sunday bitcoin price of $3673.

The reboxetine currency fell more than 3%, at the time of the transaction price of about $0.321. On the weekly chart, the current price is less than $0.332, XRP this week the price of less than $0.337, the January 14th report of the week highs.

In the first 20 encryption currency, the same day suffered the most significant loss is IOTA (7%, NEO, down nearly) and Cardano (BCH) (bitcoin cash fell more than 6%).

The total market value of all encryption currency currently about 1197 billion dollars, less than $1225 billion, which is reported to the value of a week ago.

As the blockchain technology network recently reported, 1 18 April in Wyoming introduced a bill aimed at clarifying the classification of encryption currency.

In addition, the recent news that Wyoming has passed two new housing bill, to create a favorable encryption monetary and regulatory environment innovation chain block.

Bitcoin latest price plunged 4%, the price touched $3500, the future is considerable?

Bitcoin prices plummeted again the latest 4%, the price touched $3500, the future is considerable?

Look at the bitcoin latest price, we can see that bitcoin fell 4%, the current price is $3500 price to touch. This decline in the process of falling bitcoin is not surprising, because bitcoin each rise decline is very large, so much, now fell 4% words is also very mediocre.

Some time ago, if bitcoin is still the price of $6000, but now fell down, fell to the lowest price of $3200, began to pick up after falling again, this trend seems bitcoin future will become how? In fact, many people still have some idea of the future of bitcoin can rise to a higher price, we can compare the 2017 bitcoin price but it can be said that the real price, the price has fallen to $20 thousand now, a lot of money inside the circle of people are therefore by the very big injury.

In fact, bitcoin itself is of no value, but with more and more people involved, bitcoin prices on the way to the top of the rise, but why will rise? Is that there are people who want to make money through bitcoin, so he didn’t have a very high price, but gradually we found that digital currency on the market is more and more, and other digital currencies relative to the price of bitcoin is very low, so the reason for the impact will bitcoin is very the large, because in the investment point of view, the degree of risk of other digital currencies without bitcoin, bitcoin because the original price is very low, then rose to a very high price, began to fall madly.

It seems to bitcoin now trend, so in the future it is possible that the price will be fixed at a very low price, but not crazy to top up, because in the digital currency bitcoin circle, so it is not the only future prices will not become very crazy, even more it was crazy, but also because the coins are fewer, but there are a lot of people are able to control the price of bitcoin virtual currency, in fact this sector has become a speculative product in the present, not the future trend, so in the future, until the real center of the digital currency the appearance, for now, to the center of the digital currency impact will become very large. For the future of bitcoin, you have what kind of view? The comments below express your views, make complaints about it!

The use of digital currency under the guise of deception, can be successful, because the price of bitcoin exists

The use of digital currency under the guise of deception, can be successful, because the price of bitcoin exists

For bitcoin or digital currency, I believe we are not unfamiliar, because now the market a lot of digital currency in the market, and now there are a lot of people are involved in the digital currency. But often there is such a group of people, they use bitcoin and block chain technology, or the concept of digital currency, on the outside but can often succeed deception.

In fact, both the block chain technology or concept of digital currency, are very good, but if they hit the digital currency banner outside the hype. The purpose is to cheat some money from your hand. But they also tend to be successful, the reason why?

In fact, since the birth of bitcoin, a digital currency is more and more in our field of vision, these people use digital currency to defraud, the reference object is the best because the price of bitcoin, bitcoin has always been a great controversy, but it’s not worth a hair has been crazy prices from rising to the highest price of $20 thousand, even now fell very miserably, and also the price of $more than 3000, so that many people think they are digital currency for gospel truth, the future can become the price of bitcoin such existence.

In fact, the so-called digital money cheat people what they do, and not to block chain technology to do things out, but simply build a website or APP, began their deception from the overall situation, the purpose is to believe them, but who cheat money only, because a lot of people on the block chain or a digital currency, simply do not understand, but to see that they give out the welfare policy, or some blueprint for the future prospect that rely on these so-called digital money can get rich, to the last words often stepped into is a scam.

They use is all yearning for wealth, think small investment can get a high return, so it can often succeed, and these so-called digital currency, and they block the chain or bitcoin, without any relationship, just to build a platform or system start to cheat, to a certain extent if they absconded. Now many people are so deceived, this would advise you, if you feel that you put money on your fine, then you can go to investment, but the 99% are in the deception, the final purpose is to let you pay to realize their dreams of wealth. Fraud based on digital currency, you have what kind of experience? The comments below, and share your experience, make complaints about it!

Night watcher a16z: block chain for the new era trend of Silicon Valley’s top venture

Editor’s note: This article from the value chain (ID:cc-value), author: -3 editor: hydrogen, Tang Han, the daily planet Odaily authorized reprint.

 Night watcher a16z: block chain for the new era trend of Silicon Valley's top venture

We believe that the three major trends of “a new era of next-generation computing platform, AI and digital currency”, as the three major trends on the era of mobile phone, social networking and cloud, mutually reinforce each other.

We are long-term investors patiently. We have invested the encrypted digital assets for more than 5 years, we have never cash these investments will not cash in the short term. We created the a16z crypto fund, is intended to be held for more than 10 years of investment.

A16z crypto

June 25, 2018, from Silicon Valley’s famous venture capital Andreessen Horowitz announced the launch of $300 million fund a16z crypto. A16z crypto with independent legal entity operating, general partner by a16z Chris Dixon and Kathryn Haun general partner of the fund as.

And those who think the blockchain project risk is too high, the traditional fund not convenient direct investment idea, the basic reason is that the a16z crypto fund established separately, in the field of digital encryption a16z investment quota is gradually close to the maximum allowed by law. The United States law, venture capital liquidity securities hold no more than 20%, and the encryption currency is liquidity of securities listed. A separate fund allows a16z to circumvent this restriction, and participate in the investment in the field of encryption currency in various forms.

As Silicon Valley’s top investment institutions, a16z entered the big block chain, worthy of attention . This article will be on the field of a16z investment blockchain history, investment philosophy, and analysis of the current situation of a16z crypto fund. Most important, in such a cold market. The carbon chain value hope readers can understand the core logic like a16z elite institutions are still optimistic about the blockchain.

Of course, everything must start from the a16z itself.

The origin of a16z

3 1994, American computer scientist James Clark invited just graduated from college Andreessen entrepreneurship. In April 4th, Clark invested $4 million, two people founded the Mosaic communications company (Netscape company). Andreessen is responsible for technology, in the day and night six months of overtime, launched its own web browser Mosaic.

In the next four months, Mosaic accounted for 75% of the share of the browser. In August 9, 1995 the company set up 16 months after the successful listing of shares listed on the first day from $28 to $75 per share, the market value of the highest hit $3 billion. Andreessen became the 1996 cover of time magazine. However, due to competition of Microsoft, in 1998 the company sold to America Online (AOL).

In 1999, Andreessen and before when the project manager at Netscape Horowitz founded Loudcloud. Loudcloud provides infrastructure services for large enterprises and Internet users, is regarded as one of the earliest to enter the field of cloud services enterprises. Looking back, the Amazon in the cloud services to earn pours, can only sigh Loudcloud Born Under A Bad Sign, empty eyes but ignore that infrastructure and the Internet environment are poor reality.

In 2001 2000, Loudcloud had just experienced regardless of the Internet bubble, bleed listed. A cry of “investors, generally considered Andreessen myth. Under pressure, the transformation of the company for 2002 years of software services, and named Opsware. In 2008, Opsware at a price of $1 billion 600 million sold to HP.

After selling the company, after much deliberation, has wealth free and worked as an angel investor Andreessen and Horowitz decided to create a two people belonging to the venture capital company. In two people rely on the reputation of the Silicon Valley, 2009 years, just after the financial crisis in the investment industry sluggish situation, the two founders still raised $2 billion 700 million, set up a Andreessen Horowitz fund.

Andreessen Horowitz also called herself a16z, 16 letters from the last letter of the A and Z and the middle of the digital 16. This name is easy to remember and have a unique style, but the alias over the name, became the most memorable name.

Set up two years aboard the Investor Rank list

According to public information statistics, the carbon chain of the a16z investment value. From 2009 years to ten years, was founded in early 2019, a16z conducted a total of 707 investment, investment enterprises reached 409, the cumulative amount of investment reached $22 billion 256 million.

 Night watcher a16z: block chain for the new era trend of Silicon Valley's top venture

The background and reasons of the two founders of a16z, the investment industry is mainly on the Internet (56.82%), mobile communication (19.40%) and software (non internet domain, 9.57%). The amount and frequency of fluctuations in investment are unchanged, there is no fixed rule.

 Night watcher a16z: block chain for the new era trend of Silicon Valley's top venture

In a rapidly changing Silicon Valley, a16z manipulation is impressive. It has invested in Skype, Twitter, GitHub, Coinbase, Ripple, BuzzFeed etc.. Two years after its establishment, the fund is the summit of Investor Rank.

Up to now, 408 projects of a16z investment in 104 projects have been acquired by IPO, or a successful exit. If the success of a venture capital exit measure the success rate of a16z is also on the front row.

 Night watcher a16z: block chain for the new era trend of Silicon Valley's top venture

With Wall Street unique Silicon Valley style

Try to sort out the a16z value chain investment style, and the reasons for its success.

1, the value of the technical team, long-term vision

One of the a16z fund founder Andreessen, 9 years old began to contact the computer, Basic language learning, just out of school will be invited and received $4 million in venture capital. Another founder Horowitz 1990 from University of California at Los Angeles, obtained a master of Science Degree in Computer Science in 1995, has 300 employees management experience.

Different from the outside of the technical staff of stereotypes, Andreessen outgoing personality and good communication, foreign exchange is mainly responsible for the company; and the Horowitz is responsible for the management. Two people have 13 years of work experience, tacit understanding, and have sufficient sensitivity for business.

Because the two founders have many years of experience in Silicon Valley, there is enough sensitivity to the development of science and technology and business, so the investment company will find some unique value space. For example, a16z for the first time investment chose to buy a $50 million stake in Skype 3%. At that time, Skype is in the internal nodes: faced with domestic trouble and foreign invasion of intellectual property litigation, the outside faces direct competition with Google and apple, a lot of people are not optimistic about the future of Skype.

But a16z think Skype still has a fully committed to achieving the mission of the core team of engineers, Skype will become a successful communication company. As everyone knows the last with 8 billion 500 million, Microsoft acquired Skype, a16z in less than two years earning over $150 million.

2, the successful bidder on costly price increase

The A round of financing in the GitHub, a16z will GitHub up to $750 million valuation, so that it has become the only A round investors. The premise of a profitable business model of GitHub is not clear, the investment of $100 million for the Silicon Valley is also not small quantity.

A16z participated in the B round of $95 million valuation of financing of Foursquare, in the C round of financing will be raised to $600 million valuation directly.

3, love chase cast, with rich resources investment

Perhaps because the eye is too good, a16z fancy enterprises often worth chasing investment; perhaps, a16z has had the support of their own love investment projects; there is a possibility that a16z is invested in the company too much, in short, with the increase of time, the ratio of a16z to recover investment is becoming more and more high. For 2009 years, most of the investment a16z is the first investment; but in the 2018 year, 60% year investment is to recover investment.

 Night watcher a16z: block chain for the new era trend of Silicon Valley's top venture

In the statistics found, a16z investment proportion is increasing year by year

The two founders of a16z have a very good business and business management experience. The use of these experiences, human resources and industrial relations network, a16z of the investment project management and guidance of investment. A16z currently has 50 employees in different departments to assist their investment in business operations, which is the investment company where the reason can often win.

In 2013 years in the field of encryption currency

As early as 2013 years, a16z began to get involved in the field of encryption currency investment. This may be related to Y Combinator in 2012 to provide funds for seed accelerator. It is in the summer of 2012, Coinbase joined the Y Combinator camp accelerate, received $20 thousand in financial support.

2013, a16z and Coinbase have invested a ripple, especially ho throw $2500 million in the Coinbase B round of financing. In the case of Coinbase, a16z after the investment style of play the most incisive, in C and E round round Coinbase, a16z have been chasing vote 7500 million and $3 billion dollars.

Below is the a16z block chain in the field of investment, made up of carbon chain value.

 Night watcher a16z: block chain for the new era trend of Silicon Valley's top venture

From the above chart can be found in the existing a16z encryption digital assets field nearly 6 years of investment experience, a total investment of 19 projects in the field, and most of them concentrate on 2018 and the seed wheel, and an angel round of strategic investment. The seed wheel and an angel round belongs to a small amount, high return, but also a high risk investment. Among them, Coinbase, BlockTower, Dfinity, Basis a16z is the largest amount of investment projects.

The establishment of a16z crypto

6 2018 25, a16z crypto.

A16z crypto wrote an introduction on the home page, explain why a16z encrypted digital assets investment. The following is the key value of the extraction of carbon chain:

1, from a historical point of view, a new model of computing often every 10 to 15 years: a large machine in 60s, late 70s and early 90s PC, intelligent mobile phone and the Internet in the late twenty-first Century. Each model to support new application platform based on the unique advantages of category.

2, we believe that the three major trends of “a new era of next-generation computing platform, AI and digital currency”, as the three major trends on the era of mobile phone, social networking and cloud, mutually reinforce each other.

A16z believes that the encrypted digital currency is one of the three trends in the new era. Due to the three major trends of last time in the layout and benefits quite successful, it also affects the public awareness to a certain extent: encryption will be a new trend.

A16z set up a new framework for a16z crypto:

 Night watcher a16z: block chain for the new era trend of Silicon Valley's top venture

In this table, there are a few people we have to meet. These people were in the ding ding, encryption monetary history, and currently has the important influence, it may also occur in the value of the carbon chain:

Chris Dixon, the master graduated from Columbia University, has an MBA from Harvard Business school. 2010 was a Bloomberg editorial for science and technology industry’s top angel investors. 2013 joined a16z as a general partner and investment company Coinbase, FiftyThree, Nootrobox and a series of projects. He is currently the director of Coinbase. Most of the investment in the field of digital encryption can be said that a16z is by Chris Dixon leadership or participation, it also bluntly not optimistic about most of the ICO. The general partner by Dixon as the a16z crypto fund is the best choice.

Kathryn Haun, graduated from the Stanford University law school, served in the United States Department of justice as a federal prosecutor for ten years. During the formation of the first government working group on encryption currency. And is responsible for the Mentougou incident and the dark net silk road event. Haun a16z is the first female general partner. In Silicon Valley the absolute “political correctness”, select the Haun for the a16z crypto impression abroad a lot of extra points, and know how to deal with the government, how to invest in the law does not improve the situation.

The biggest highlight is to join the Dan Boneh, he graduated from the Princeton University, CO director and professor of computer science at the Stanford University in 1997 and served as the research center of the Stanford University is the blockchain. The papers are cited 73370 times, which in 2014 has been cited 34499 times.

(source: Google scholar)

Join the Dan Boneh for a16z crypto also said the fund is currently disguised for infrastructure (public chain, a smart contract) the demand will increase and a high degree of attention.

Block chain is mainly composed of cryptography, consensus mechanism and game theory, consensus mechanism and game in the present application is single, the digital currency will do the encryption on Dan, Dr Boneh also has a lot of space to play in the field.

A16z crypto’s portfolio and investment logic

A16z crypto official website page reads:

We are long-term, patient investors. We ve been investing in crypto “assets for 5+ years. We ve never sold any of” those investments, and don t plan to any time “soon. We structured the a16z crypto fund to be able to hold investments for 10+ years.

(translated into Chinese: we are a long-term investor patience. We have invested the encrypted digital assets for more than 5 years, we have never cash these investments will not cash in the short term. We created the a16z crypto fund, is intended to be held for more than 10 years of investment).

According to this investment logic, a16z is probably the most a fund for long-term layout of the field of encryption currency. It may be too early to participate in the cloud service and founder of Andreessen, but failed to get to the end, can not enjoy the return on. (although this is a serious analysis of the article, but I really want to make complaints about: 10 years cash Token Fund where to find……)

The following is the a16z crypto official website revealed the portfolio:

 Night watcher a16z: block chain for the new era trend of Silicon Valley's top venture

The official website revealed the portfolio

According to the portfolio, we can see that the a16z crypto investment are more aggressive and more extensive selection. In the case of DFINITY, choose the digital currency rather than equity investment; in bitcoin, obtained by mining way selection.

To hold for ten years as the goal of the fund, to profit is not the immediate change, and to infrastructure to target only in this industry. Announced portfolio confidently expressed this point:

1, Bitcoin and Ethereum are the two most mature industry chain.

To the center of the exchange 2, DFINITY developed a cloud computing and dYdX will be the next trend.

3, intelligent and stable currency is a part of the contract the chain application and the transaction is not open around.

The first paved infrastructure, and then tap the next scene in infrastructure under perfect conditions. This is where a16z crypto is now doing.

summary

Although encryption currency market is winter, but a16z believes it and computing platform AI, the next generation, will become the future trend. A16z did not cash in the past 5 years in the field of digital currency investment, and it is specially established on digital currency fund a16z crypto, ready for their investment in digital currency project held for more than 10 years.

We do not know whether the temperature of encryption currency has become warm, but a16z has started a false start. Perhaps this is why the a16z.

This paper will put forward some suggestions, tell you how to hold, but not in the final earnings before early exit.

Why bitcoin will fall?

During the bear market, many people are not very happy. Your anger is not so strong, because most people look forward to fall is temporary. As the bear market continues, people began to become more and more uneasy.

Expect bitcoin will rise, or at least stable. In other words, people expect a linear development. Because bitcoin average earnings for the past 7 years for x%, they hope that this situation will continue.

Of course, not in the real world, anything is a linear development. This also includes bitcoin. Things change rapidly, this is completely normal. For example, bitcoin prices experienced 80%+ collapse.

The real reason for restless heart is eager to do real work in the case of money. In fact, if bitcoin can at a steady rate rise, there is no need to work to make money. (Translation: that is to say, in reality there is no such linear thing.) Let us look at the bear.

Why the bear was so bad?

First of all, the bear market funds pressure. Those who can’t handle the pressure will bring economic loss to you. If you have no leverage or transition to hedge, when the arrival of the bear market, your position may not. When you can’t afford to wait, it is easy to out. This is bad.

So, the first rule of investment is not being eliminated. The bear is the rule play the biggest role.

Secondly, the bear market has the social pressure. Not only the financial pressure, and social pressure, critics will tell you: I already told you so. Your friends and relatives will bring greater pressure on you. When the bull market, people will treat you as a genius, when you bear, may be miserable.

Again, resulting in fewer opportunities to make money market. When the bull market, there are numerous start-up companies and projects in the desperate, the opportunity to make money almost everywhere. If you have relevant experience, you can earn a lot of money, such as through consulting, market etc.. However, the arrival of a bear market, the situation becomes difficult. People began to think you had plenty of money of no great importance, the project began to tighten the budget.

Why the bear has a good side?

First of all, the bear market may get rid of the bad investment projects. During the bull market are worthless raised too much money. Some projects just a white paper, to raise billions of dollars. In the past few years, the blockchain investment is crazy, many projects will disappear. This is a good thing, because these resources will be allocated to the project good project. According to the Austria business cycle theory, market adjustment will make the good company and project better. That is to say, money will flow from the project project. This is a good thing.

Secondly, the bear market may expose the really important things. Under the huge pressure of the bear market, only really useful to survive. We can find out what is the most important thing for people, because people in the bear market will be careful to choose what you want. People no longer participate in any 1c0. People began to look to see things, to more rational choice. People are no longer worried about missed opportunities. The more intelligent the market is a good thing, because a better allocation of capital can bring a more prosperous future.

Again, the bear market can teach you a clever and hard work. In a bull market, a lot of work in the bear market, work hard to find. This means that, as a candidate, one must provide real value, also means to be smart and work hard. In the bear market, once a person does not provide real value will be fired.

Finally, the bear market can develop themselves. Many people complain that the early use of bitcoin is how lucky. The long-term holders were not lucky, they are convinced that. A lot of people to buy bitcoin in 2011-2012 years, but a lot of people are sold, because for them, this is the toys, games, trading. They do not understand bitcoin, of course, they may not believe it. Hold for a long time is not easy, especially the long bear market. When an asset fell more than 80%, you will still have? Easily in the bull market. To bear market and continue to hold that need to have their own.

You have to make sure not out of their positions, only frugal living. You must carefully plan the future, and strive to adhere to their own values. The bull gives you space. Bear to allow you to make some difficult choices. If you can experience these, this is the opportunity for self development.

conclusion

A bear market is a necessary part of any economy, especially the overheated investment in the past few years the case. This will lead to the re allocation of resources, to the people really want to project. There is too much deviation over the past few years, the field of encryption, need to re adjust the actual utility based, rather than based on commitment.

This adjustment is not easy, but if you can come out from the bear market, perhaps it is worth it. Because the next bull market you gain.
