i have seen "china is banning bitcoin" for years now.
its a bit ridiculous to scream that every couple of months now, and i really don't think most people care about what might happen, because most likely china would just reverse itself as it always does a couple of months down the line
I also see what you say is not wrong, China has done something like this several times but will eventually come back to it. we know, however, China is a very large crypto user and it is not easy to prohibit it unilaterally because there will definitely be an impact that will occur.
I don't think the bank is so strict that people will not be able to bypass the ban on cryptocurrency. There are many ways to bypass the ban on Bitcoin and making people had been doing that for long now. There are also other countries that crypto is ban but there is still ways to use crypto with the government even know about it. I just hope the ban on Bitcoin and other altcoins would end as soon as possible so people that are full crypto traders and investors would be able to do there businesses without any problem at all.
