The disadvantages of digital currency
compared with traditional bank transfer, remittance and other methods, digital currency transaction does not need to pay fees to a third party, and its transaction cost is lower, especially compared with cross-border payment which provides high service charges to payment service providers
2. Fast transaction speed
the blockchain technology used in digital currency has the characteristics of decentralization, High anonymity
in addition to the point-to-point transaction without intermediary participation, one of the advantages of digital currency over other electronic payment methods is that it supports remote point-to-point payment, It doesn't need any trusted third party as an intermediary, and the two sides of the transaction can complete the transaction in a completely strange situation without mutual trust. Therefore, it has higher anonymity and can protect the privacy of traders, but it also creates convenience for cyber crime, which is easy to be used by money laundering and other criminal activities
1. Secure
transaction of cryptocurrency on the decentralized platform of blockchain, the E-wallet used by it is authorized to send and receive cryptocurrency by the cryptosystem using the unique public key and private key. And the account does not need to be identified by a third party, so outsiders can not know the identity of the trader
2. Tamper proof
after the transaction on the blockchain is confirmed, it is tamper proof, and this kind of data is traceable, so the illegal elements can't cheat by deleting or modifying the records
you can learn about cryptocurrency through some media platforms, so I won't go into details here.
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
