> Proof of Work/Stake only matter if Bitcoin is actually being used as a trustless and anonymous payment system for regular transactions, which is ironically the task that (among most other cryptocurrencies on the market) it's perhaps least suited for technologically.

I agree that many cryptocurrencies are not suited for this... but some are, and of those, Cardano is proof-of-stake from launch, has ~50 billion USD market cap, 20s to 1 minute confirmations (up to 10 for complete irreversibility, but one confirmation is really reliable already), an amazing community, relatively low fees (about $0.20 USD right now but hopefully decreasing in the future), ability to support 1 million transactions/s without fee increasing, and extremely high decentralization.

I agree that many cryptocurrencies aren't suited to real use at scale as a transaction layer, but I think the hype about the power of this when done right is very fair.
