If your goal is to passively hold coins without losing share, Ethereum is the best option I know of.
With both PoS and PoW, a holder loses share when the total coin supply increases. On Ethereum at least, this is less of a problem with staking than mining, because staking is less costly so there's a tenth as much issuance.
However, with sufficient usage, the ETH supply actually shrinks, because a portion of fee revenue is burned. This means non-staking holders actually increase their share.
