Think about all the bitcoins held by Chinese because they can't sell them. Choking off supply has always been the most effective way to pump a coin.
Those are mainly coins held by miners, and they can easily sell by doing under the counter deals with various exchanges. Chinese can still travel, so a quick trip to Korea or Hong Kong is easy and the deal can be conducted there.
that is right, chinese can handle and make a rate control by their miners, because of that i hate chinese hahaha
but they are easily to travel to another country like you wrote up there,
