In fact, I am also curious, if the assets are rich enough, can the price of Bitcoin be manipulated? So Bitcoin is still decentralized? If it happened, wouldn't the value of Bitcoin be determined by whales?
Bitcoin is completely decentralized, one or more individuals, institutions, and groups do not control Bitcoin. Bitcoin whales are organizations, individuals, and groups that hold 1000 or 1000+ bitcoins. Yes it may be somewhat true that bitcoin whales may temporarily have some effect on the bitcoin market. For example, if Michael Sheller sells all his bitcoins in the market at once, the bitcoin market will be affected to some extent. Bitcoin whales will not completely destroy the Bitcoin market.
