It may be like that initially, people are only worrying and assume that China's policy is the main influence. However Bitcoin is a form of economic revolution desired by many people, China must really make something new more innovative and can change the attraction.
China can only ban but it can't stop. In the end Bitcoin enthusiasts will get used to it without China's role.
They are not really after getting the attention, they just do not want anything they can't control at the hands of their people and that's it. I do not care if there are anyone who would be supporting China, I really do not care, but the reality is that china is ruled with dictatorship, last time people wanted to fairly elect others the nations soldiers killed people, it is still remembered to this day.
Long story short people should not really be hoping China to get back in to crypto world, we have heard maybe 10+ times so far that "china bans bitcoin" so far, most of the time they "ban" it and others still keep doing it in secret, but the reality is that china will NEVER support bitcoin and crypto fully, why? Because, it is decentralized and they hate things that are not centralized, hell Chinese government actually owns 50% all companies there, that is how their nation work.
