Bitcoin is currently have the biggest market cap between all crypto, i think only whales possible to manipulate the price. Many early adopter of Bitcoin bought alot of BTC with very cheap in 2010, and some of them holding about 1% of total supply so will be more easy for them to manipulate the price.
It seems there is an impression that many early adopters are still holding their coins and that is simply not true, many early adopters sold their coins immediately or they used them to buy stuff back in the day, only the most fervent believers in bitcoin held their coins believing that something like this could happen anytime soon, so even if people do not like their influence they deserve it.
