China has blocked the country’s Bitcoin exchanges from accepting new inflows of cash. The price fell and it's just ridiculous. I mean, if we suppose that people are smart enough to understand it but its never true... Lack of cash on chinese exchanges actually means that deposits are more valuable... They can sell deposited accounts from person to person. Thus, price should grow. They just need some time to understand that simple thing...
You are thinking from an early adopter's or long time speculator's perspective, not from a Chinese "investor's", who just found about Bitcoin a few months ago, and thought he could make a lot of money in short-term. This kind of people tend to panic from the slightest disturbance.
