Just what I am thinking about. I believe that bitcoin prices are being manipulated but I don't know how can they manipulate the market, that must be the person has so much power in crypto world.
It is simple they orchestrated news, some huge sell within themselves. They often time it when there is some crisis or conflict within cryptocurrency that they think may affect bitcoin price. This manipulators have huge stash of Bitcoin and/or huge fund to play the market. It is not a single person I believe but rather groups of person that wanted to take advantage of high volatility of Bitcoin and the weak hands that bought Bitcoin during the hype.
