Hopefully everyone with move to Ethereum and other Proof of Stake coins.

(Both for the environment, and my wallet since I'm already deep in Eth)

Proof of stake is not secure in the same way as proof of work. Miner collusion attacks are free in PoS, expensive in PoW.

It's only "free" if you get a substantial fraction of the coin's total wealth backing your attack.

And it's not really "free", because you'd instantly devalue the currency itself (and thus your own stake).
