BTC international station
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. Problems in the development process need to be standardized<
extended information:
people who really own bitcoin do not store the token on the Internet, but store the currency in the hard disk. Bitcoin's code is open source, which means that technologists 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.
