Daily news of digital currency
Generally, the excellent digital currencies are mostly imported procts, such as bitcoin, Leyte coin, ether coin and so on. However, the domestic Yuanbao coin, Ruitai coin, bitcoin and the tokens of different crowdfunding projects of European crowdfunding are excellent digital currencies
digital currency (English: digital currency) is an alternative currency in the form of electronic currency. At present, no central bank of any government has indicated that it will issue digital currency, and digital currency does not have to have a benchmark currency and a central bank
it 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 currency, such as bitcoin, lightcoin and ppcoin, is an electronic currency created, issued and circulated by check sum cryptography
according to incomplete statistics, more than 200 counterfeit coins have been proced since 2014, and more than 100 have survived. The life cycle of Shanzhai coin is generally about 2-3 months. Because the purpose of some Shanzhai coins is to earn money without any innovation. When the price is high enough, the makers will sell a lot to cash out. Without the support of the makers, this kind of counterfeit money will eventually die.
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

The biggest significance of promoting digital currency is to bring more convenience to people, and the management of currency by the state is easier, which can eliminate the circulation of counterfeit currency to a great extent. When we go to the bank to withdraw money, it is more efficient and convenient for us to carry money. In addition, it has the function of anti-corruption. Every digital RMB will have a circulation number. If there is corruption, you can easily find out. You can also control the source of money
What is the difference between digital RMB and other payment methodsthe money deposited in digital RMB is actually money. Each RMB has its own circulation number, which is not only the form of amount. Other payment methods like the payment of UnionPay or WeChat or Alipay payment only transfer the amount to other people's mobile phone, but not the circulation of RMB. The money in the digital RMB app is equivalent to the money in the pocket. As long as it is not spent, the money in it will not be much or less. And there is money in bank Alipay WeChat, there are still some interest per day. br />
