If Musk wanted to pay 44 billion for Hive, that would price each HIVE at 114 dollars, but of course, due to liquidity, it would likely be closer to 500 each. Would you sell knowing that the culture would be ruined?
If Elon musk should pay such amount for the hive blockchain that means he would be in charge which probably wouldn't fit the blockchain since it's not owned by one person.
Yes. He'd have to buy everything, meaning everyone would have to sell. Not likely. Though, at 500 a HIVE, there would be plenty of takers.
