China regional chain digital currency

1. Thank you
thank you
to know the difference between them, we need to know the definition of them first
digital currency: short for digiccy, which is the abbreviation of "digital
currency", is an alternative currency in the form of electronic currency. Both digital gold coin and cryptocurrency belong to digiccy
blockchain: blockchain is a new application mode of distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm and other computer technologies. Blockchain is essentially a decentralized database, also known as the trust machine
from the above definition, we can know that blockchain is a technology, and digital currency is a kind of virtual currency
digital currency is not equal to blockchain
many people will understand blockchain as blockchain. Here I want to correct that digital currency is not equal to blockchain. Digital currency is only an application of blockchain, and some digital currencies may not be applied to blockchain technology.

2.

As of May 2020, blockchain and digital currency are illegal in China

according to the announcement of the people's Bank of China Central Network Information Office, Ministry of instry and information technology, State Administration for Instry and commerce, China Banking Regulatory Commission, China Securities Regulatory Commission and China Insurance Regulatory Commission on preventing the risks of token issuance and financing, Article 2 no organization or indivial shall illegally engage in token issuance and financing activities. Organizations and indivials that have completed the token issuance and financing should make arrangements such as refund, reasonably protect the rights and interests of investors, and properly handle risks. Relevant departments will seriously investigate and deal with the activities of token issuance and financing that refuse to stop and the illegal behaviors in completed token issuance and financing projects

Article 3 strengthen the management of token financing trading platform

from the date of this announcement, any so-called token financing trading platform shall not engage in the exchange business between legal currency and token and "virtual currency", and shall not buy or sell token or "virtual currency" as a central counter party, and shall not provide pricing for token or "virtual currency" Information intermediary and other services

extension data

"illegal financial institutions and illegal financial business activities ban" stipulates that:

eleventh, the criminal suspect, funds and property involved in illegal financial institutions and illegal financial activities, and the public security organs shall take compulsory measures according to law to prevent suspect from escaping and transferring funds and property. p>

Article 12 the people's Bank of China shall, after investigation and confirmation, make a decision to ban the illegal financial institutions and financial business activities, declare them illegal, order them to stop all business activities, and make an announcement

Article 13 if the people's Bank of China discovers that a financial institution opens an account, handles settlement and provides loans for an illegal financial institution or illegal financial business activities, it shall order the financial institution to stop the relevant business activities immediately. No unit or indivial may use the relevant funds without authorization

3. There are many of the best blockchain digital currency trading platforms in China. Please pay attention to the distinction. Foreign ones can also be used.

4. At present, there is no final conclusion. In the past 17 years, it has been stipulated that it is illegal. However, the national laws already have a sense of supervision in this aspect, and some relevant policies and regulations will soon be issued to regulate and regulate the blockchain, which means that there will be legal blockchain in the future.

5. Blockchain digital currency refers to cryptocurrency. The underlying technology is blockchain. There are many cryptocurrencies. bitcoin is more famous. Detailed digital currency can be found in cryptofinance mimacaijing.

6. There are not too many reliable domestic digital currencies. Generally, most excellent digital currencies are imported procts, such as bitcoin, Leyte currency, ether currency, etc
however, Yuanbao coin, Ruitai coin, bitcoin and the tokens of different crowdfunding projects in Europe are excellent digital currencies.

7. The above formula is not perfect, because the direction of wind speed is not necessarily perpendicular to the action surface θ
F= ρ S(v*sin θ)^ 2
the formula is deced as follows:
consider the case that the wind speed is perpendicular to the action surface first
take the cross section of the wind as s and the length as S Δ x( Δ x-> 0), and the velocity before the wind contacts the action surface is v Δ x=v Δ T
the mass of the air column is Δ m= ρ S Δ x= ρ Sv Δ T
because the mass of the air column is very small, when it collides with the action surface, it will move along the action surface, that is, its velocity perpendicular to the action surface is 0 Δ t=0-(- Δ MV)
i.e. F Δ t= ρ Sv Δ t*v
F= ρ When the wind speed is not perpendicular to the action surface, the velocity is divided into the direction of the vertical action surface and the direction parallel to the action surface. Since the component parallel to the action surface will not generate force with the action surface, the final wind force is only the component perpendicular to the action surface, which is v * sin θ, Substituting this formula into (*) to get
F= ρ S(v*sin θ)^ two

8. As for the so-called bitcoin, it is not protected by law now, so it can not be purchased because there are some illegal means to raise funds and operate illegally.

9. After 9.4 last year, the domestic digital currency exchanges were closed down, and the domestic ICO was also prohibited
