I fear for ETH future, almost all smart contract projects are using the PoS staking algorithm but only ETH PoW stands alone, this makes ETH different and one of a kind smart contract project, I think vitalik buterin will regret is decision after ETH goes PoS.
Why should you be fear for ETH's future? I think the ETH team thought about it before, and if the ETH project is going to be any different than before, maybe it's one of the ways for ETH to continue to change and grow big and survive any upcoming trends in crypto. We don't know if Vitalik Buterin regrets his decision or if he sticks with it. If you are afraid, you don't need to follow ETH and instead look for other coins that you think don't scare you.
