we all know no one can controls the bitcoin price because bitcoin isn't like bank, stock and valas. but if the whales owned 51% of bitcoin, can do it?. if happen, does decentralization not exist?
There's no such thing as bitcoin being controlled by any individual or group of individuals called whales, it might seem they have a good amount of ownership of bitcoin but that doesn't give them a chance to alter the decentralization that exist within BTC. They might influence news and speculations about the coin to trigger some actions amongst the small boys in the market (it's all market psychology strategy) but that doesn't in anyway make them have control to market price outcome.
In the past whales used to play a big role in the price manipulation. The big bag holders try to increase the holdings out of the small holders through panic news spreading. When there is very small number of users available in the market, this has been possible and now things weren't the same as past. Now influencers and other whales into the market try to have control over the market. This is possible to some extent and further it is the common users and the technology that derives the value. Whales are part of the market who have the ability to make some disturbance in the market than controlling.
