Here we go again with Bitcoin, PoW === All cryptocurrencies.
So all cryptocurrencies are Proof-of-Work and non-Proof-of-Work cryptocurrencies don't exist today? Perhaps XRP, Nano, Stellar, Solana, Algorand, and Hedera are all destroying the environment and are slow for payments?
I mean I don't even like the hype around cryptocurrencies, but the main reasons presented by this RFC for not using them are quite weak and completely outdated. Yawn.
