In my opinion, although China's new policy of prohibiting mining will cause the price of Bitcoin to fall in a short period of time, but for a long time, it is good for the development of the Bitcoin ecosystem.~
Agreed, just like @mk4 said, it does not affect and will not correlate to the fundamental Bitcoin. Personally, in fact, it will give attraction to the mainstream. Bitcoin has been said is dead multiple times, and also China was "banning" mining since a long time go. Thus, it gives a realization to a lot of people that Bitcoin cant be controlled by a singly entity even an governments. Nevertheless, we must maintain this decentralization based on the fundamental of Bitcoin. Since a privileged early bird in these cryptocurrencies has a probability to be an elite cryptocurrencies community.
