The point is even more dramatically illustrated if you zoom out further and show 2004-present, assuming your point is that "crypto" as a contraction of "cryptocurrency" is extremely recent; the usage is less than a year old, and therefore likely to confuse those of us who have been using "crypto" as shorthand while discussing "cryptography" for multiple decades.

(Perhaps linguistic coherence is more than we should expect from the cryptocurrency community, given that they have already inflicted upon themselves the utterly bizarre usage of "blockchain" as a mass noun.)
