I believe that its a fear hyped campaign to make a new entry point for rich people. I believe that if China bans the exchanges, the coins will have greater scarcity involving a large % of the trading population. There will be less coins floating around being traded, meaning harder to sell, harder to buy. I think the price will increase because the coins will be in fewer hands than previously, a consolidation if you will. I am not selling.
There are many news from the past that bitcoin got it's dumped little of the price. So I don't believe this will give a huge impact to bitcoin to over dump the price. Somehow, bitcoin will recover and will continue to increase. Others will buy back at a good price to earn a good profit.
