Sometimes being there first doesn't mean you get to use the simplification forever. Cryptography is an older thing than cryptocurrency, but both are unwieldy to pronounce and have been simplified to "crypto". Since cryptography is math and cryptocurrencies (in the "popular" sphere) is a get rich quick scheme, the abbreviation that works for both generally became applied to the latter.
I am sure organic chemists are a little weirded out when people tell them "oh yeah I love those new strawberries we got". This is that.
If airports, phones, and corner shops claimed they 'work in crypto' it would be similarly misleading.
Even Toly refers to himself as a distributed systems engineer, because building a blockchain involves more DS work than crypto work.
FWIW I work in web3/defi, used to work in PKI.
