In essence, it can directly solve the BTC problem

1. 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. 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.

2. At present, only a few algorithms of virtual currency are meaningful, such as XPM (prime currency, used to solve prime numbers), GRC (Greider currency, used for scientific operation), etc. I have been using CPU to dig XPM, although my income is limited. In fact, these currencies also have the excellent properties of bitcoin, but they are not favored by most virtual currency lovers. The price is very low, which is really distressing.

4. This still depends on the resources. Professional mining machines are very profitable, and ordinary mining machines may be suspended. Look at the flow of ore mining, we know that the super miner's income is more cattle.

5. What do you ask?

6. Foreign payment is generally credit card, not as convenient as domestic.

7. If you want to play with precious metals, you can learn some financial knowledge, but don't touch what you don't understand. You can't make all the money, but you can lose it! Bitcoin advises you not to touch it. No matter how much you toss about, it's Nakamoto and his several people who always make money. This thing has no value in itself. It's nothing more than speculating the price up. This is no essential difference from the Ponzi scheme. Whether you can make money depends entirely on your luck.
