it is proof that rich people or whale still has power to influence or manipulate bitcoin price. I think is a good chance for other rich people to buy btc at lower price. He is not the only one rich person in this world, maybe if other rich people see opportunity to earn profit in bitcoin investment then they will get involved in it.
Just imagine that we know that the Crypto market is going to fall like the way we experienced it, this would have bring a huge profits to us because we would have set a sell limit with a big leverage that is going to earn us a very huge profits. The market is being manipulated always and we that don't understand how the market works will never know what we are missing and those things we don't know.
A big whale can decided to sell part of his Bitcoin to crash the market and buy back again when the market falls to earn more profits for himself. This is what most whales do and inform others to do the same that is why when the make a speculation, it does go in there direction mist time.
