China's expansion will not stop just by banning crypto, but they will do other things to conquer all countries.
China doesn't like crypto and they want to bring down the market in their own way. the presence of bitcoin can destroy the market competition they have been running for so long. we know that bitcoin is not going to stop because of the news and we will soon see bitcoin rise.
they have also banned CMC, COINGECKO, and others. China is serious about this ban. and they do not create a gap for their citizens to play a role in the crypto industry.
They will see that they can not do that for their people because once their people do not like it, they will reject the regulations. Once that happens, we might see a war inside their country and if that happens (again), I can not imagine how many people would be killed.
They need to realize that the world is changing, so they need to adjust and follow the technology and not prohibit their people from using something that can change their lives or country. I am not sure if that ban will really happen for a long time but let see what will happen later.
