I think bitcoin market is not controlled, bitcoin is hold by more people and market can't be controlled. Bitcoin is mined. Bitcoin should value more because there is limited supply and demand is high.
No one has 100% control over the markets, but it can definitely be controlled to a certain extent. Whales, news sites(crypto and non-crypto), certain personalities(crypto and non-crypto), and even the government, can affect the markets one way or another.
Though as time goes and liquidity gets better, it gets harder and harder to manipulate BTC's price.
