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.
The competition is gettin tough, if ETH didn’t adopt or no more updates then that is the time for you to worry about its future. So far ETH is still doing good on trying their best to stay on the competition. The most anticipated update of ETH 2.0 can be a big thing, and maybe this is the reason why ETH is still the top altcoins, they see good things are coming.
