Bitcoin restrictions
There is no law in China to ban bitcoin, so it is not illegal to mine and earn bitcoin
it is not illegal to buy bitcoin in China. In 2013, five ministries and commissions jointly issued the bitcoin risk notice, which states that although bitcoin does not belong to legal tender and is not legally compulsory, people can freely participate in bitcoin trading activities when they voluntarily undertake risks
"notice" clearly defines the nature of bitcoin, and holds that bitcoin is not issued by the monetary authority, has no monetary attributes such as legal compensation and mandatory, and is not a real currency. In terms of nature, bitcoin is a specific virtual commodity, which does not have the same legal status as currency and cannot and should not be used as currency in the market
however, as a kind of commodity trading on the Internet, ordinary people have the freedom to participate in bitcoin trading at their own risk
the notice requires that at this stage, financial institutions and Payment institutions shall not price procts or services with bitcoin, buy or sell bitcoin as a central counterparties, underwrite insurance business related to bitcoin or include bitcoin in the scope of insurance liability, and provide other bitcoin related services to customers directly or indirectly, Including: providing bitcoin registration, trading, clearing, settlement and other services for customers; Accept bitcoin or use bitcoin as a payment and settlement tool; Carry out bitcoin and RMB and foreign currency exchange services; Carry out bitcoin storage, custody, mortgage and other services; Issuing financial procts related to bitcoin; Take bitcoin as the investment target of trust, fund, etc
in order to avoid over hype of virtual commodities such as bitcoin in the name of "virtual currency" and damage the public interest and the legal tender status of RMB, the circular requires financial institutions and Payment institutions to correctly use the concept of currency in their daily work, pay attention to strengthening the ecation of the public's knowledge of currency, and correctly understand the concept of currency The concept of correctly treating virtual commodity and virtual currency, rational investment, reasonable control of investment risk, and maintenance of their own property security should be included in the content of financial knowledge popularization activities, so as to guide the public to establish a correct concept of currency and investment

theoretically, 2100 trillion, or 250.899. In terms of selecting this value, this number is far less than 264-1, which is the largest integer that can be stored in the form of standard integer in a computer. If it exceeds that value, the bitcoin value will return to zero like a odometer
but this is only theoretical, just theoretical. Just like the previous IP address regulations, no one expected that V4 would be used up so quickly. Now it is necessary to use V6. This so-called "maximum integer that can be stored in the form of standard integer" may be broken by the technology upgrade one day a year later, followed by the collapse of the whole bitcoin computing.
in the first four years, 50 pieces were g out every ten minutes: 50 * 6 * 24 * (365 * 4 + 1) = 10519200 pieces
in the second four years, 25 pieces were g out every ten minutes: 25 * 6 * 24 * (365 * 4 + 1) = 5259600 pieces
according to the sum formula of infinite equal ratio sequence, the final total amount is infinitely close to 21038400 pieces (10519200 * 2)
as long as the mining rules are not changed, the number of bitcoins will never exceed 21038400
freedom of payment - you can pay and receive any amount of money anytime and anywhere. No bank holidays, no borders, no imposed restrictions. Bitcoin allows its users full control of their funds
very low fee - at present, there is no or very little fee for the processing of bitcoin payment. The user can include the service charge in the transaction to obtain the processing priority and receive the transaction confirmation from the network faster. In addition, there are also merchant processors to assist merchants in processing transactions, converting bitcoin into legal tender every day and depositing the funds directly into the merchant's bank account. Because these services are all based on bitcoin, they can offer much lower fees than paypal or credit card networks
rece business risk - bitcoin transactions are secure, irreversible, and do not contain customers' sensitive or personal information. This avoids the loss of merchants e to fraud or fraulent chargeback, and there is no need to comply with PCI standards. Where credit cards are not available or where fraud rates are unacceptably high, businesses can easily expand into new markets. The end result is lower costs, larger markets, and less administrative costs
Security and control - bitcoin users have complete control over their own transactions; It is impossible for businesses to impose fees that may occur in other payment methods that should not be or are not easy to find. Payment with bitcoin can avoid binding personal information in the transaction, which provides great protection against identity theft. Users of bitcoin can also protect their funds through backup and encryption
transparent and neutral - all information about the bitcoin funding itself is stored in the block chain and can be verified and used by anyone in real time. No indivial or organization can control or manipulate the bitcoin protocol because it is password protected. This makes the bitcoin core believed to be completely neutral, transparent and predictable
of course, digital currencies such as Ruitai coin, Qianjin card, Laite coin and doggy coin also have these advantages, but their acceptance and popularity can't be compared with bitcoin.
the risk of all financial procts is that after the depreciation of the financial procts, they may not appreciate or return to the price when you bought them on time
that is, your property is trapped in it, and you are unwilling to sell it after devaluation. Wait, I don't know that you can't get it back until the end of the year. Maybe, just like China's stock market, you can't stop losing. The more you wait, the more you lose
