Unfortunately I think this fight was officially lost when noted cryptographer Matt Blaze gave in and sold the crypto.com domain to a blockchain company. (I don't blame him for doing so, I just think it's a noteworthy event.)

What I mean is: I agree with you, but I think the crypto ship has sailed.

For what it's worth I started backpacking in the 1990s and back then "crypto" to me meant cryptosporidium, the 2nd biggest concern about drinking backcountry water (after giardia).
