The technological case against Bitcoin and blockchain
I found it excellent. It summarizes the main paradox of crypto: if you make it truly decentralized, it costs too much and is useless as a mass medium of exchange, while also being a haven for fraud and theft. If you rely on any sort of ledger&#x2F;layer 2 system, you are back to trusting a third party, in which case you would be better off with traditional banking.
