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.
At the end of the day ETH has always been a centralized project which is why vitalik can take those kind of decisions unilaterally, I think it is a mistake for ETH to go from PoW to PoS, and we can see this is the case as ETH has been trying to make that transition for a long time and it has yet to achieve the results the developers want, however even if they can move successfully to PoS the network is not going tob e as secure as before and ETH will be just like most other smart contract coins, losing any edge it may had in the market and putting at risk its position as the second most important coin in the market.
