Basic knowledge of digital currency
Digital money (electronic money or electronic currency) is a kind of money in digital form (different from paper money and coins)
it shows properties similar to physical currency, but it can allow real-time transaction and borderless ownership transfer. Examples include virtual currency, cryptocurrency and currency issued by central bank and recorded in computer database (including digital base currency)
like traditional currencies, these currencies may be used to purchase physical goods and services, but they may also be restricted in some communities, such as online games
digital currency is the currency balance that is electronically recorded on stored value cards or other devices. Another form of electronic currency is network currency, which allows value transfer on computer network, especially on the Internet. E-money is also a creditor's right to other financial institutions such as private banks or bank deposits
digital money can be centralized, that is, it has a central point to control the money supply, or it can be decentralized, that is, the control power can have different sources
From 2015 to 2017, the price of bitcoin increased from more than $100 to $17000, a 100 fold increase. Today, the market value of various numerical currencies is more than 700 billion US dollars. The myth of their benefits is not nonsense
but there are many things behind the chaotic digital currency. You may ask why air currency can be listed on the stock exchange? It's very simple. The exchange also has to charge a part of the fee. Raise the price and then sell it to make money. So the question is, how to identify air currency
first of all, you need to look at the projects behind the digital currency and see what their team background is. Generally speaking, teams without experience in the instry tend to earn money, but how much experience do they have? It is better to be able to participate in the construction of Ethereum and bitstock communities. Such a team is often more reliable. This requires investors to have a certain screening ability to identify good or bad
secondly, there is no way to implement many projects. How can we identify them? In addition to the ability of the team, we also need to see the feasibility, which requires us to systematically learn the knowledge of bitcoin and blockchain. For example, Zhu Jiawei, the COO of fire coin network, learned the blockchain from 0 to 1, and clearly described the development process of bitcoin and blockchain in the form of audio and text. Besides, don Tapscott and Alex Tapscott's "blockchain revolution" are worthy of careful taste
moreover, the bubble of digital money is very large nowadays. In the bubble, it is not difficult to make money, but the key is not to be greedy. Long term holding is not good, but it can be operated in a short term. You can make money if you want. However, the key is that people are all profit-making and greed is their nature. Therefore, many people do not accept what they see. They originally made money, but later they lost everything. The gain is not worth the loss. Therefore, it is necessary to control greed
Digital currency is a kind of legal tender, which must be issued by the central bank. Both digital gold coin and cryptocurrency belong to digital currency, which is not a network virtual currency, because it is not limited to virtual space, but is often used for real goods and services transactions, such as bitcoin, Wright coin, bitstock, etc. at present, there are thousands of digital currencies issued around the world

1. Impact on financial infrastructure
the decentralized mechanism of value exchange based on distributed ledger technology has changed the basic settings of gross and net settlement on which financial market infrastructure depends. 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
If digital currency and distributed ledger based technology are widely used, it will bring challenges to the intermediary role of financial system participants, especially banks. As a financial intermediary, banks perform the ties of acting supervisors and supervise borrowers on behalf of depositors. Usually, 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 mechanismsafter poisoning, the computer often fails to power on normally. When restarting the computer, press F8 all the time to enter the advanced option, and then enter the computer system from the network security mode. The first thing after boot is to carry out anti-virus treatment immediately.
