Most bitcoin prices are tied to an average or a collection of what the top exchanges publish as the current bitcoin price. But who's actually moving their prices? From my understanding, retail users don't have the power to move prices in the short term. Whales supposedly are the ones who can make the price suddenly jump or drop...but they trade on OTC desks right? not on retail exchanges....so how are these Whale movements being reflected on retail exchanges to determine what the current bitcoin price is? Or are there actually some whales who use the exchanges to trade on?
If you are going to check how the market works or the crypto currencies prices works. Their prices will vary to the buyer or holder, meaning if the demand will grow then the price will also increase.
So the direct answer to your question, the one who actually move the price of bitcoin and other crypto currencies are us who are buying it but those big whales or big investors have the control as they have the bigger percentage of holding compare to us who only have a very few percentage of holding base on our current investment.
