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.
Ethereum is an improvement over all of them, many smart contracts are using them, even if examined closely, projects that have a greater success value are using their smart contract network, and the prospect of Ethereum using PoS will have a huge impact going forward, as they are figuring out how to use Ethereum must master any exchange, be it transactions, swapping or buying/selling in their smart contracts
