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!!
The problem is that they don't talk to each other, don't coordinate with each other, and don't even trust each other. If one of them sells, the others have no way of knowing if he's trying to crash the market, or just buying another Lamborghini.
i agree they probably don't trust each other, but by means of blockchain analysys it should be pretty easy for them to contact each other, they just need to find big wallets and contact them with their own big wallet. The protocol allows for this kind of messaging and once they know they are in the same boat (yacht in that case) it could become logic to not fight to each other, in that case trust should matter less than one may think
