PoS is sort of hard to bootstrap. ETH moved to it which was quite an achievement, but it’s difficult to see how it might have started that way.

If Bitcoin fails then it seems to me the bottom will fall out of all of crypto So all of it still depends on PoW propping up BTC.

I wouldn't say there any major technical hurdles to bootstrapping PoS, the project just has to decide where the initial tokens should go - insiders, ICO, airdrops, etc. Many modern chains have been PoS from the start, like Cardano, Solana, Algorand, Avalanche, NEAR, etc.

Or do you mean in the sense that (some argue) the most fair way to do an initial token distribution is PoW with no premine?
