At the beginning of the new year in 2021, bitcoin is close to US $35000, and traditional media are competing to report that great changes have taken place in the currency circle, which has aroused the attention of all parties. Let’s review the new year. The first notable change in the currency circle last year was that bitcoin prices hovered around $7000 in early 2020. By the end of the year, bit broke through $30000, a record high. Bitcoin is the highest rising asset class in 2020. Since September last year, institutions have entered the market crazily, creating “bitbull”. In December, there was a trend of accelerating the admission of institutions. It can be seen that traditional institutions are paying more and more attention to the cryptocurrency market, and the accelerated admission of institutions is positively related to bitcoin breakthrough. In the past year, the regulatory authorities of the United Kingdom, the United States, Singapore and Hong Kong, China, have successively issued their own regulatory standards for cryptocurrency, and the global financial action task force on money laundering has issued the world’s first cryptocurrency regulatory standard. In addition, Hong Kong has issued digital asset licenses to the OSL digital asset exchange, marking the birth of the first licensed digital asset exchange. The third change that must be paid attention to last year is that the investment channels of digital assets are more diversified, which gives more basic and investment encryption ways. For the expansion of the cryptocurrency market, the gray bitcoin trust fund was launched in the past year. Payment software PayPal, stock software and other end-users with greater influence in the field of financial payment. Through the cooperation with the compliance encryption asset broker, it develops the transaction interface to the user, and manages the encrypted asset for the user. Users don’t need to develop additional accounts, and one click access to encrypted assets reduces the investment threshold. The fourth most noteworthy change in the currency circle last year was the increase in the application of Ethereum in finance and the launch of the Ethereum 2.0 project. Ethereum will also be the focus of the coin circle in the next few years. After several years of development, it has become more and more mature. First, there was a cryptocat in 2017, and then this year’s wave of defi broke out. All of these have directly exposed a series of problems of Ethereum, such as high network congestion, high service charge and slow transaction speed. Eth2.0 is expected to be imperative. On December 1, Ethereum 2.0 beacon chain was officially launched. The beacon chain is only in the zero stage. One segment will be launched next year, and the second segment will start processing transactions. More optimizations will be achieved. The development of Ethereum 2.0 in the next few years is still an important event in the currency circle. Last year, the fifth most noteworthy change in the coin circle was more active exploration of blockchain technology at home and abroad. Last year, the total market value of usdt exceeded US $20 billion, and the issuance scale of stable currency reached US $27 billion, reaching an all-time high. Stable currency is gradually replacing bitcoin and becoming the mainstream payment tool in the encryption asset industry. In addition to stabilizing currency, major financial enterprises have been actively exploring blockchain technology in the past few years. Blockchain is expected to become the core technology of the next generation infrastructure in the financial industry, Among domestic enterprises, ant financial, Ping An, Tencent, Huawei, Vientiane and other companies occupy an important position in the world.
