If a whale can make some money by moving the market with his large holdings, what is wrong with it?
By knocking it down too much.
They should keep it fluctuating at a level. Even if they are manipulating the market, they should keep it at one price range. It was good when they kept it at $800 or $600 but now they keep sinking it slowly. People will lose trust in BTC. The Chinese will leave. The Chinese are driving the price up and the stupid western whales drive it down. At least keep it at $500!!
