You don't necessarily need to own a lot of the market to make it swing wildly. You just need moments of low liquidity and some weak hands bought in near the highs. Bitcoin has both. Price is simple a function of what people are prepared to buy and sell at any moment in time. IN low liquidity you can make it do some real funny things.

Not saying it will happen, just that it's possible. But the usual banker protocol is to big up what your selling to bagholders, and to talk down what you want to buy.
