China has 20% of the market so it wont hurt bitcoin thath much...it already bounced back from its drop. Nevertless there are always going to be oportunist ready to fill in the space that CHina left..so there is no need to worry... CRYPTO IS UNSTOPABLE.
There are a lot of other countries who knows about bitcoin that its existing in their country but still they are quite if chain banned bitcoin in their country
so it doesnt bring any decline on it bitcoin is still alive are working properly so to say we will be die without china its totally wrong.
