The fact that POS encourages holding alone dooms any POS coin imo. For any coin to succeed it need adoption, which implies actual spending. At least with POW there's often a better distribution of coins which leads to a decently sized community working for adoption, as opposed to POS when there's like 3 whales staking 70% of the supply spamming posts about how amazing a coin is...

Sure you can argue that POW coins can have a similar situation with insta/pre mine but assuming a fair coin reward system, once the mining community matures for a POW coin the coin distribution will always be fairer than a POS system, which is the first step towards adoption.

just my 2c ofc
