the concept of bitcoin was first proposed by Nakamoto on November 1, 2008, and was officially born on January 3, 2009. According to the idea of Nakamoto, the open source software is designed and released, and the P2P network on it is constructed. Bitcoin is a virtual encrypted digital currency in the form of P2P. Point to point transmission means a decentralized payment system. Unlike all currencies, bitcoin does not rely on a specific currency institution to issue. It is generated by a large number of calculations based on a specific algorithm. Bitcoin economy uses a distributed database composed of many nodes in the whole P2P network to confirm and record all transactions, and uses cryptography design to ensure the security of all aspects of money circulation. The decentralized nature and algorithm of P2P can ensure that it is impossible to artificially manipulate the value of bitcoin through mass proction. The design based on cryptography can make bitcoin only be transferred or paid by the real owner. This also ensures the anonymity of money ownership and circulation transactions. The biggest difference between bitcoin and other virtual currencies is that the total amount of bitcoin is very limited and it has a strong scarcity

This situation must be timely feedback to customer service, to retrieve

if bitcoin is stored in the account of the exchange, all the coins are in the big account of the exchange. If the exchange stops trading or goes bankrupt, all the coins belong to the actual controller of the exchange (the person who has the key of the big account)

therefore, if there are official problems in the exchange, we must contact the official customer service in time to retrieve them. In addition, digital assets, blockchain and other technologies will have unpredictable effects, and problems in the development process need to be standardized

extended information:

people who really own bitcoin do not store them on the Internet, but store them on the hard disk. Bitcoin's code is open source, which means that technicians can modify the code to proce a continuous stream of virtual currency

which breaks through the "limited amount" attribute of bitcoin. These virtual currencies can be exchanged with fiat currencies. For example, bitcoin can be exchanged into yen, and yen can be exchanged with almost all fiat currencies in the world

in this case, if the number of virtual currencies increases arbitrarily, there will be problems in the whole international monetary system. Therefore, on September 4, 2017, the central bank stopped the exchange function of the token trading platform, especially the exchange function with legal tender

7. Bitcoin is a virtual currency, the world's general cryptocurrency. Just like sending and receiving e-mail, the remitter pays bitcoin directly to the other party through a computer or smart phone according to the recipient's address. But it's going to close soon. Bitcoin is a decentralized and open source digital currency, which will eventually reach a fixed unit of quantity: 21 million, which will not be reached before 2140. The current rate of money proction is 25 new bitcoins per 10 minutes, and the number will slowly decline. It will be halved in 2017, and then it will be halved every four years until it reaches the upper limit. Now who are the people who get those bitcoins that are proced every 10 minutes? It's a technical process, which is essentially to solve difficult mathematical problems, and hard systematic work will be rewarded. In short, mining is a process of running a program, which helps to verify transactions on the network. Unlike other transactions, it is completed by solving difficult mathematical problems. This special process also leads to its becoming a kind of free currency. Every few minutes, a new bitcoin finds a miner, so that they can protect themselves. Now mining is becoming more and more difficult. Under the leverage of market economy principle, their prices will be higher and higher. If the utilization rate is higher and higher, the prices will be higher. Using bitcoin, you can buy goods and services, convert them into real currency at any time according to the bitcoin exchange rate at that time, and sell bitcoin to other users. If you want to join the mining team, the early hardware and power costs are inevitable, so you can try various hardware settings and calculate its mining efficiency. Risk the price fluctuation of bitcoin is its biggest risk, because the whole market value has reached 1 billion US dollars, many people are eyeing this market. Last month, the value of a bitcoin rose from $30 to a peak of $75; But in 2011, the exchange rate of US dollar to bitcoin fell from US $33 to US $2.51, and it took a long time to recover. Now its transaction value is 125 dollars, so it is very valuable. Instawallet was closed as a bitcoin hosted wallet on Thursday because of the attack, and it indicates that 90 days later, if no one else claims to have received the same URL, users under 50 bitcoins will recover 50 bitcoins. For indivials, if you pay attention to privacy, want to trade a small amount of money without government regulation, and have a wallet that can be entrusted with the custody of bitcoin, you can have a try. There is still a long way to go before it can replace the existing currency. The infrastructure under it needs to be well constructed to be generally accepted. If you want to buy one or two in the near future, it is absolutely no problem.
