Many of the world's leading exchanges are from China and with a daily trading volume of billions of dollars, China's total ban on bitcoin will probably have very bad effects on the market in the near future. When the CEOs of the world's leading electronic exchanges are arrested or detained, how will the market fluctuate?

I believe FUD is always a reason for concern. It means fear, uncertainty and doubt and it's a card used to destabilize something. In this case it was the strategy used by China to destabilize bitcoin. China created the FUD to spread fear, uncertainty and doubt among investors and this fact is easily noticed on reality as we can see many people are showing such symptoms right now.
China is provoking a readaptation in bitcoin businesses' allocations, what may have a very negative impact over btc on short run, but I think we should always think further, because once this readaptation is completed, bitcoin will be doing well again.

Yes I hope so. Same strategy in the past few years and this I experienced it. It's like there used to be McCafee and now Elon. There used to be bad news and then good news. Today, of course, after FUD there is good news. This happened, planned and definitely this was done to enrich and increase the number of their assets. I truly believe blockchain technology will develop rapidly with its new generation. So don't worry it's a process.

Just because the source power issue from mining abuse and now they prohibit the exchange and ownership? I don't really follow this but if it's true I think the decision is unfair, they should just ban massive mining not restrict exchange.

I agree with this opinion because despite the fact that China is crackdown on bitcoin mining it is positive because mining companies will have the advantage of operating with better conditions taking into account what interests us in that the extraction is friendly to the ecosystem and there are no irregularities. I would love for bitcoin mining companies to move to the United States.

Do people still take China seriously on these regular or should I say phenomenal crypto related activity bans? Becuase, I see no reason why crypto investors should. It just doesn't add up to me. For the past few years, China and other governments of the world has targeted different aspects of the crypto space and yet have made zero significant damage to the crypto ecology. With the series of tries from China alone, I think  a normal crypto investor should know better than to take the China FUD for making any market decision.
We ought to know that we are the market and our individual decisions matters. Having the feeling that other investors would go with the regular sentiment associated with this news is way too traditional to stick with. We've got to evolve better.
