I was heard the news that's China has planning to be launching their bitcoin and their blockchain, but as we can see China are the mostly country that's affected by CORONA... So it is possible for them to launch their bitcoin at the moment?
Bitcoin is a decentralized cryptocurrency, and states, and China, are primarily not interested in a decentralized cryptocurrency, which is very difficult to control.
States are now working on the creation of their national stable coins, that is, digitized their currencies. This is not “your own bitcoin”, because with bitcoin and a decentralized cryptocurrency, stable state coins have practically nothing in common.
