I think who control price the crypto market is big investors, they can control in low price and then to the high price. Everything of cryptocurrency depends on them, that prices go up and down because of the consequences of our own selling btc at a low price.
I agree because always for major investors there is a big place in the crpto market because unlike the rest investors who invest or sell few amount of currencies the effect of major players actions are much higher due to the large volume and with that market price can be changes highly during purchases and selling so in a way we can say big investors controls large part of the currency market
