1) Bitcoin adopted Blockchain to solve the double-spend problem, the most brute-force approach to solve it, which doesn’t scale to make a “peer to peer cash system”
2) Around 2013 the narrative changed to a “store of value” and some drunk guy’s misspelling of HOLD became a rallying cry
3) Ethereum and others continued to use blockchains with balances instead of UTXOs, which is even less scalable (https://iohk.io/en/blog/posts/2021/09/10/concurrency-and-all...).
4) And now the technology is entirely unnecessary for NFTs, the industry should have started with NFTs and worked backwards to implement currency
Ok this is getting long… see https://intercoin.org/presentation.pdf for what needs to happen for crypto to get past “number go up” speculation and power real adoption. Counterpoints welcome.
