Ah. Quite. I not only misunderstood that, I fell into the trap you’re complaining about, read your comment too fast, and associated ‘crypto’ with ‘cryptocurrencies’.

Related, and perhaps to salvage something productive from my confusion: I think we’re well past being able to rescue the word ‘crypto’ from being synonymous with cryptocurrencies in general, and blockchains in particular, in the minds of most. For general ‘crypto’, I think it’s time to start using ‘cryptography’.
