You’re best off making peace with it as that genie is not going back in the bottle.
Indeed. "Crypto" has very much gone the way of "hashtag" (which is, amongst non-technical people I know, overwhelmingly used to refer to the hash symbol).
The irony is crypto means hidden which cryptocurrency isn't.
Depends which one you're talking about.
To be fair, doesn't the "crypto" in "cryto-currency" mean "cryptographic"?
