It will be surely bad if those thousands of Chinese speculators will be shut out but it will not make Bitcoin "die". Far from it sir.
it's enough to set everyone else off into a panic to put it in the doldrums for a long time. and it's probably hundreds of chinese speculators. everyone else on the chinese markets is american or european.
I think the Chinese speculators will affect the price of bitcoin quite a lot. If they are not allowed to own bitcoin, the price will drop.
