I dont sure that its a good idea, China have a massive population that can help and raise the exchange rate of the currency at he future..

So you'd rather China control the price of bitcoin the way they are doing now? Government calls for ban, prices drop, retract ban, prices rise again?

China aren't controlling the prices.

True its the sheeple and mental traders who reacts to any chinese news who control the market. China farts and bitcoin price drops $50 .

Exactly.

Chinese like to publish rumors affect Bitcoin development, we can easily believe.

It's normally FUDsters that publish the rumours, not China.
