This is a common crypto talking point but it makes no sense.
Companies are regularly acquired at a premium to their market cap, often in cash. For instance, Elon Musk signed an agreement to pay $44 billion to take Twitter private. Assuming the deal goes through, every single shareholder of Twitter is going to receive cash in exchange for their shares.
There's no such process for cryptocurrencies. It wouldn't make any sense for someone to acquire every instance of a coin. Coins don't pay dividends. They don't represent any kind of underlying assets. It's just weird to pretend that they have a market cap in the same sense as stocks.
