It will be interesting to see what sort of impact it will have when China are allowed to operate exchanges again and whether that will be negative or positive for Bitcoin.
Of course, the market would be reacting positively to this development considering that China is a big market for cryptocurrency and this market actually remains untapped as Bitcoin has just started to get through the mainstream population when the government decided to made the big ban last September. Hopefully, when China can be back on the table it would push the price of Bitcoin further into the sky as the demand in China is right now brewing up. Hot Chinese money is soon coming back to the Bitcoin ecosystem so that means a lot. By hot I don't mean illegally-made money.
Personally, though am not looking forward for China to be back in the Bitcoin marketplace all because China had been that big source of so many headaches in the past which many times push the price of Bitcoin on a roller-coaster. Right now, it can be said that Bitcoin actually does not need China (it can be the other way around, though!) and the future of Bitcoin can still be beautiful without China.
So should we then tell China not to do the comeback anymore? Well, hope I got the power to do so but am just a poor and ordinary guy eking a good living with the help of Bitcoin.
