We can not do anything with bitcoin because chinese demand is too high and Once there are anything happened with bitcoin or chinese investors of bitcoins. that is very big problem because They owned biggest bitcoins in the world (90% bitcoin amount from China). I think we need another digital coin for the rest of the world.
Where did you get the source that 90% bitcoins are from China, that's an absurdly high number.
In fact over 90% of bitcoin are mining in china, The same number also for traders, exchangers and blockchainer. News and fundamental issues affect bitcoin because majority of magin traders and speculative traders are Chinese. If others developed countries keep on rejecting bitcoin and others cryptocurrencies, than Chinese will keep on control the crptocurrencies world.
