This is not crypto news, but cryptocurrency news.
Is it accepted? I would agree only when it appears in the NYT or The Economist with its 'new' meaning.
It's a subset of lazy people in tech who are abusing 'crypto' at this point in time, not Valley Girls. There's an inflection point here to interdict the abuse, before it gains mass-usage.
Also, the headline clearly says cryptocurrency, it seems to be the domain name he is complaining about.
Sorry, I don't agree with adding 8 letters to a url to make a very small segment of people (who are apparently not the target audience) happy.
It's like saying butter when you mean butterscotch. Doesn't mean the same thing and shouldn't.
Bait?
In either case, crypto is an abbreviation.
