Such as Chinese gov cancels the restriction to financial institutions dealing with Bitcoin.
There's discussion in China of reducing exchange controls on yuan. But if China reduces exchange controls, people with yuan in China won't need Bitcoin. The China bubble was because, for a brief period, Bitcoin was a safe, legal, remote way to convert yuan into dollars or euros. The previous legal approach was to get all your relatives to travel to Hong Kong every three months, loaded up with the legal maximum of yuan notes. This is a pain if you're not in Shenzhen. If you have no idea what the above is about, you probably were screwed by the collapse of Bitcoin prices.
... there are more and more ppl wanting to buy thus it will go up even in the face of big sellers.
