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?
^ That needs a lot of financial support if you wanted to hold 51% of BTC, I dont think there is a whale will risk at that high amount, whales can move a certain price but that is not a lot, it could be a huge loss into their pocket too if they will do this. There is no one controlling the price even how rich you are, it depends on how the adoption will grow. Decentralization still does exist as long as the BTC network is still there that publicly seen transactions, remember the purpose of BTC and why it was created.
