In order for China to be competitive in the field of crypto-currency with other leading states in this field of activity, it is necessary that it constantly interacts with other countries. For now, we see that China protects itself from other states and prohibits the use of decentralized crypto currency in their country. However, at the same time, blockchein technology is being introduced into practice at a much faster pace than in other countries. It seems to me that they do not deny the crypto currency as such, but they are looking for their own ways of using their types of crypto currency. China is still experimenting. It should be recognized that such a special approach of this country in many cases was crowned with success. It is necessary to watch very carefully what happens to the crypto currency in China.
