Adverse effects of digital currency
Yin Zhentao, deputy director of the law and Finance Research Office of the Financial Research Institute of the Chinese Academy of Social Sciences, said that digital currency faces two risks. The first is the technical level. Digital currency relies on blockchain technology and a system, which will make it suffer from security impact, such as hacker attacks on computer systems. We have seen many practical problems in this process
Zhao Zhanzhan, a special researcher of intellectual property research center of China University of political science and law, believes that digital currency has anonymity, quickness and irrevocability. In addition, bitcoin and other digital currencies have high circulation in the world, so many criminals use digital currency as a new money laundering channel. Moreover, there are many different ways to realize money laundering through digital currency. Generally speaking, the probability of new money laundering being found and investigated is lower than before. Many countries have no effective means and technology to combat money laundering through digital currency. These factors lead to criminals prefer this way of money laundering
many procts of blockchain technology are not currency, although they are called currency. Under the guise of digital currency investment, it is a Ponzi scheme. Even some of them don't even have blockchain technology, which is just a fake number to cheat people.
we can understand that digital currency is an account book containing all historical transactions. Each block will have several transaction records, which can be viewed by all participants. Each participant of digital currency has to maintain this account book together, Digital currency is a collection of transaction data
for example, in the field of digital currency bitcoin, there will be the concept of "miner". Miner needs to constantly repeat operations to generate workload, and each miner has competition. It needs to complete a mathematical problem based on cryptographic hash algorithm. The answer is in the area, if who works out the answer first, So who can broadcast in the network that he has obtained this block, other miners will not go to this block for mining, but will work in the next block. Miners will have more transaction costs in his block, and they will generate what we call digital currency bitcoin as a reward, and then they will go to their own digital currency bitcoin account
there is no problem with digital currency itself. There may be criminals using digital currency as a cover to cheat, which needs to be carefully screened
1. The volume of digital currency is too large. With the development of digital currency, the volume of digital currency stored in nodes is becoming larger and larger, and the computing burden is also increasing. Colleagues have also caused a lot of impact on the operation of digital currency bitcoin client
2. There is a problem with the data confirmation time. The time for a digital currency bitcoin transaction is about 10 minutes. If we confirm six times, we need to wait for an hour, which is a long time;
Digital currency is a double-edged sword. On the one hand, the blockchain technology it relies on has been decentralized and can be used in other fields besides digital currency , which is one of the reasons why bitcoin is popular; On the other hand, if digital currency is widely used by the public as a kind of currency, it will have a huge impact on the effectiveness of monetary policy, financial infrastructure, financial market, financial stability and so on. Specific Wu Xiaoxia:
1. Impact on monetary policy
if digital currency is widely accepted and can play the role of currency, it will weaken the effectiveness of monetary policy and bring difficulties to policy-making
because digital currency issuers are usually unregulated third parties, money is created outside the banking system, and the amount of circulation depends entirely on the wishes of the issuers, which will lead to the instability of money supply. In addition, the authorities are unable to monitor the issuance and circulation of digital currency, which will lead to the inability to accurately judge the economic operation and bring trouble to policy-making, At the same time, it will weaken the effectiveness of policy transmission and implementation
2. Impact on financial infrastructure. The use of distributed ledgers also poses challenges to trading, clearing and settlement, as it promotes the disintermediation of traditional service providers in different markets and infrastructures. These changes may have potential impacts on market infrastructure other than retail payment systems, such as large payment systems, securities settlement systems or trading databases
3. The impact on financial intermediation and financial market in a broad sense. As a financial intermediary, banks perform the ties of acting supervisors and supervise borrowers on behalf of depositors
generally, banks also carry out liquidity and maturity conversion business to realize the financing from depositors to borrowers. If digital currency and distributed ledger are widely used, any subsequent disintermediation may have an impact on savings or credit evaluation mechanisms
4. The impact of security risks and financial stability
assuming that digital currency is recognized by the public, its use increases significantly and replaces legal currency to a certain extent, negative events such as network attacks on user terminals related to digital currency will lead to currency fluctuations, which will have an impact on the financial order and the real economy
in addition, the virtual currency based on blockchain technology is usually held by a few people at the beginning. For example, the first purchase of bitcoin in May 2010 was $25 pizza purchased by 10000 BTC, and the price of each bitcoin rose to $1200 in more than three years by the end of 2013

Amazon will launch digital currency project in Mexico. Amazon is recruiting software development managers for digital and emerging payments (DEP) to develop new payment procts that will enable customers to convert cash into digital currency
the digital and emerging payments sector intends to launch the proct in Mexico first. The follow-up will be extended to Brazil and India. It is reported that the digital currency project will completely focus on payment services in emerging markets
