Digital currency re invested every day
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

this kind of Trojan Horse & quot; Kidnappers & quot; The encryption method is complex, using 4096 bit algorithm, violent cracking takes hundreds of thousands of years, supercomputer cracking takes more than ten years or even decades

and it uses bitcoin for & quot; Ransom;, This kind of virtual currency is characterized by decentralization, anonymity and can only be used in the digital world, so bitcoin transactions are difficult to track. At the same time, Trojan criminals also hide in anonymous networks. This anonymous network named tor has exposed & quot; Prism project & quot; Snowden, a technical analyst at the U.S. Central Intelligence Agency, once recommended it because it allows users to access anonymously and ensures that the servers they use cannot be traced
In a sense, it can really be compared with gold. But bitcoin is a deflationary currency, which makes it somewhat similar to gold. The new gold g every year in the world is far behind the expansion of economic scale, let alone the circulation of legal currency. Therefore, the continuous appreciation of gold can also be seen as the continuous depreciation of legal currency relative to gold
however, in the recent global economic turmoil, when the stock price and oil price fell sharply, we found that the market's safe haven funds did not flow to bitcoin, the price of bitcoin fell sharply, but the price of gold was very strong
this shows that bitcoin as & lt; Digital Gold & quot; This status has not been recognized by the global mainstream. Because the price of bitcoin is the result of the game in the global market, a small number of determined users actually have no effect on the price of bitcoin. In my opinion, the mainstream market does not recognize the hedging property of bitcoin, which just shows that bitcoin has huge risks
I think the biggest risk of bitcoin in the future is not quantum computer cracking encryption algorithm, because this risk is graally accumulated, and only need to replace the existing algorithm with more advanced anti quantum encryption algorithm. This is a normal technology upgrade, and does not affect the value of bitcoin
the biggest risk of bitcoin comes from its consensus, that is, the constant total amount of 21 million is actually realized through code, and the logic of halving every four years is also realized through code. If the upper limit of 21 million is cancelled in the future, for example, it will not be halved after this halving (around April 2020), and inflation will continue at a constant rate, that is, changing a few lines of code, It's very simple
seeing this, senior people in the currency circle will certainly laugh at me for worrying about nothing, because if we break the consensus, bitcoin will no longer be bitcoin, it will be worthless
