Technically speaking, any movement in the crypto market or maybe any type of market actually happens because of some people. Not always those people intentionally manipulate the market though and sometimes it's a result of a particular trend or domino effect. Once the price starts falling everyone just tries to secure their portfolio by selling which is simply what I mean by a domino effect.

There might be such forces or whales as we usually refer them to, but there is no proof or solid evidence that can support such claims. Influencers obviously manipulate the market but there must be some whales who do the same behind the scenes and through brute high capital investment.
