Am certain ethereum will crash In the same way, as if Jeff Bezos sold all his Amazon shares overnight. Amazon's share price would plummet.
Why would that happen? Simply because the market would have big doubts about the survival of Amazon and here of Ethereum.
Everyone would say that if Vitalik Buterin is selling all his ETH, he knows about something serious that we don't know about.
Vitalik Buterin, like Jeff Bezos, has no interest in doing this. Worse, he would be forever hated by the Ethereum community and could do nothing in the cryptocurrency world.
It is not in his interest to do this as it is for Jeff Bezos with his Amazon shares.
LOL. This will never happen man, even if VB decides to sell all his Ethereum and move on, he is not dumb, he won't do it in a way it will affect the Eth price in the market, he wil probably be selling it bit by bit maybe in an extended period of like a month or two or half a way or even one year depending on the amount of Ethereum coins he owns.
Ethereum is already a very big ecosystem which I believe can survive without VB, check what happened with dogecoin, dogecoin founder sold every thing and abandoned the project way back in 2015(if am not mistaken), fast forward to 2021, dogecoin made it to top 4 on coinmarketcap. Buterin is going no where, even if he does, Ethereum is old enough to survive without him.
