1. The concept range is different. bitcoin is a kind of digital currency, and the concept of digital currency covers bitcoin
However, some digital currencies have independent issuers The biggest difference between bitcoin and other virtual currencies is that the total quantity of bitcoin is very limited and it has a strong scarcity. The monetary system used to have no more than 10.5 million in four years, after which the total number will be permanently limited to 21 milliondigital currency is abbreviated as digiccy, which is the abbreviation of "digital currency" in English. It is an alternative currency in the form of electronic currency. Both digital gold coin and cryptocurrency belong to digiccy. Bitcoin is a digital currency
digital currency is different from the virtual currency in the virtual world, because it can be used for real goods and services transactions, not limited to online games. The early digital currency (digital gold currency) is a form of electronic currency named after the weight of gold
today's digital currencies, such as bitcoin, lettercoin and ppcoin, are electronic currencies created, issued and circulated by means of check sum cryptography. It is characterized by the use of P2P peer-to-peer network technology to issue, manage and circulate currency. In theory, it avoids bureaucratic examination and approval, so that everyone has the right to issue currency
illegal digital currency
in recent years, "virtual currency" represented by bitcoin, Ethernet currency and Leyte currency has been traded centrally on some Internet platforms. With the help of financial technology, the price of these "currencies" has graally spread to investment, financing and other financial fields, which has aroused wide attention from all walks of life
not long ago, the people's Bank of China and other seven ministries and commissions jointly issued the announcement on preventing the financing risk of token issuance, which clearly regulated the relevant behaviors. Experts pointed out that "virtual currency" is not legal tender (legal currency) issued by monetary authorities, but a specific virtual commodity in essence
therefore, it is undoubtedly a great legal and economic risk to think that "virtual currency" has or will have the nature of legal tender and to carry out speculation, network fund-raising, lending and financing
For many people, the concept of digital currency is a mystery. But there is no doubt that digital currency is different from virtual currency
At the same time, digital currency is different from electronic payment. In the actual use experience, digital money and electronic payment may feel similar, but they are still quite different in essence. Before digital currency, the financial instry has been highly informationized. Such as Internet banking, WeChat, Alipay and so on pay the popularization of electronic technology, physical cash accounts for only a very small part of the total circulation of money. In spite of this, because the money used in the transaction comes from the bank account, it actually corresponds to the banknotesthere is no price limit for P.S. digital currency trading, so investment should be cautious!
the digital currency launched by the central bank is a national sovereign currency, which is based on the digitalization of RMB. This is a piece of data generated by a complex algorithm, which contains blockchain and encryption technology, making it unique. The payment of Alipay and WeChat is not digital money, but only based on the payment realized by electronic accounts. Compared with the current pattern of "payment transfer collection" with the help of third-party payment, what digital currency needs to achieve is "decentralization", that is, to cancel the transfer link and directly hand over the money from the payer's account to the payee, so as to rece the payment cost in currency circulation
types of digital currency
according to different issuing or consensus mechanisms, it can be divided into four categories:
1, proof of work (POW)
proof of work. The system rewards are obtained through the mining of computing power to complete the issuance and distribution of currency. More work, more gain. Such as bitcoin, lightcoin (LTC)
the advantage is that the mining cost can form a monetary price support to a certain extent, and the disadvantage is that energy consumption and environmental protection are criticized< 2. Proof of stake (POS). Allocate the newly generated currency or interest according to the amount and time of cryptocurrency you hold. Such as dash and Neo
compared with pow, POS is more energy-saving, but it increases the security risk
3. The evolution scheme of delegated proof of stake (dpos)
POS. Similar to the voting mechanism of the board of directors, through the election of representatives to vote and make decisions, n accounting nodes are elected to create, verify, sign and supervise each other. Such as the grapefruit coin (EOS)
the advantage is high efficiency, but the problem is that it presents a semi centralized state
4. POW + POS hybrid mechanism
POW is mainly used to issue currency, and POS is used to maintain the system. For example, PPC
according to the project type, it can also be divided into four categories:
1. Currency category
digital currency issued for the purpose of transfer, payment and value storage. For example, bitcoin, bitcoin cash (BCH), Monroe (XmR), and grin
2. Public chain currency, that is, the digital currency issued by public chain projects, is generally the "fuel" for the application projects to run on the public chain. Such as eth, grapefruit coin, TRX and ont
3. Application token, that is, digital currency issued by decentralized application projects, is equivalent to equity or points. For example, OMG (payment application), GXC (data application), 1st (game application)
4. Platform currency, that is, the digital currency issued by the digital currency exchange, is equivalent to equity, points or fuel. For example, BNB, HT and okb.
it's not a reality. Up to now, I still think it's stupid to make money by buying and selling domain names. I know it happens sometimes. It's like a high-risk, low return investment
as a result, the Internet did. Now, 20 years on, domain names are cheap, and search engines make them brand specific Note: the author means that the convenience of search engines makes domain names cheaper and cheaper. Domain names are only related to brands.)
What does this have to do with the value of bitcoin
this is an example of how people's views on value change with the development of technology
at this point, most people see bitcoin as money. The chairman of the US SEC said, "yes, that's how drug gangs use it. Everyone I know thinks so.". It's called "bit coin" for a reason
bitcoin maximalists call it hard currency, critics call it fake money, and veteran players call it cyber 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 allows immediate transaction and boundaryless 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, they may be used to buy physical goods and services, but they may also be restricted in some communities, such as online games
