These comments make more sense when you realise that bitcoin is more of a religion and way of life than a technology. Nothing can ever be bad for bitcoin because it’s an accepted fact of life that bitcoin _is_ the future.
OTOH sha256 proof of work mining is a billion dollar industry and the Bitcoin mining hashrate just hit an all time high after a long protracted bear market.
Miners are in the black, price will follow
Edit: a word
I don't believe in crypto. But I know plenty of religious zealots to sell it to. So I'm happy to own it. My bet is it isn't a dying religion.
1) Divine creator whose existence is impossible to prove
2) A holy book: (whitepaper) that's taken as absolute truth and therefore doesn't require any revisions or updates. Proposed changes to core beliefs create split factions (BTC v BCH, Old v New Testament, or the Shia-Sunni split in Islam).
3) Monotheism: Belief in the primacy of Bitcoin blockchain over all other competing chains, and warning of divine punishment for apostates (NGMI).
Is it perfect? No.
Is it ages ahead of Bitcoin? Yes
