extended data
at present, digital currency is more like an investment proct, because it lacks a strong guarantee agency to maintain its price stability, and its role as a value measure has not yet appeared, so it can not be used as a means of payment. As an investment proct, digital currency cannot develop without trading platform, operating company and investment company
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 except 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 and financial stability
On September 4 last year, the central bank issued a document explicitly calling for a halt to the financing of token Issuance - that is, the ICO ban. This kind of illegal sale and circulation of tokens by financing entities to raise so-called "virtual currency" such as bitcoin and ether coin from investors is prohibited in China
now that more than half a year has passed, what is the situation of these "virtual currencies" boasting "blockchain technology"
the reason why Yang Chao invested in virtual currency is mainly e to the price fluctuations. Bitcoin, for example, emerged in 2009, with less than one cent per bitcoin. In less than ten years, its price once exceeded 120000 yuan. Under such a soaring market, the mentality of being able to get rich overnight attracts a large number of investors
After95, there are 1000 bitcoins, which is the symbol of Zheng Haosheng in the "coin circle". In one year, he turned the 140000 yuan principal into several hundred million yuan. At present, he still has more than 50 different tokens. But professional investors like Zheng Haosheng are not always winners
ZHENG Haosheng, a virtual currency investor, said that in the past two days, he had a direct loss of 200 bitcoins, worth 10 million, and an indirect loss of about 30 million. How many people earn, how many people lose, more people are in the loss, blindly admission, 80% are in the loss
According to the data, there are about 1600 kinds of virtual currencies in the world. The cumulative daily turnover is more than $10 billion. Among them, bitcoin's daily turnover is about $6 billion. Domestic investors are big buyers of global "virtual currency"Mao Hongliang, director of the blockchain Research Office of the national Internet financial security technology expert committee, said that taking the largest international platform as an example. It is monitored that from 2018 to now, the exchange transaction volume between digital currency and RMB is about 1.3 billion yuan, accounting for about 13% of the total transaction volume of the whole platform
instry insiders say that the most dangerous thing in the bubble is the "air money" which is not supported by physical projects. P>
2018 January 15th, known as the world's first support for digital encryption currency gaming platform hero chain, on-line "break", from the issue price of 0.6 yuan to 0.05 yuan
IT community and service platform vice president of CSDN Meng Yan introced, this can be more confidently known as air money, accounting for it is hard to say, but under the bubble, this ratio is not small. It may exceed 50%, 60% or even 70%
"air currency" is different from other financing projects, the financing subject of issuing financing does not need to be a real company, a temporary "team" can become the financing subject. After the central bank banned the issuance of token financing, the original domestic token projects have chosen to move their servers and the registered places of financing entities abroad. The token financing project with the "team" as the main financing body does not even need to move the registered place out, and it can continue to raise money as usual
Mao Hongliang, director of the blockchain Research Office of the national Internet financial security technology expert committee, said that many ICO subjects are just a team, and many of them are not registered to the company level, so it is difficult to say that there is a company subject or an enterprise subject
