On the timescale of the past 4-5 years, you are correct about the popular usage.

However, if cryptocurrency continues to recede from the public eye, then in another 4-5 years I think "crypto" will no longer mean "cryptocurrency".

Understanding both the current lexicon and the "archaic" and "recently archaic" uses of the term I hold is both useful and pertinent to being able to communicate effectively. Which is why I immediately clarified, I'm talking about the 40+ year definition of the term, not the current whimsical linguistic fad.
