The ban on cryptocurrencies must be correct. The government is not afraid of cryptocurrencies, but is worried that many people will go bankrupt during the growth period. Only when the cryptocurrency market is re-accepted by the government will they be open. This is to protect the people, knowing that countless scammers want to rely on fraud to get rich overnight, which is much faster than any investor making money.
Cryptocurrency is prohibited because the government sees something that is not true in its application, so if want to be accepted there must be a mutually beneficial correction. It is impossible for a policy to be implemented by the government if it harms one party.
