When I see the word "cyber", it is a good indicator that the speaker who uttered this word has absolutely no idea what they are talking about. This is usually underlined by their business card using the same word (such as "head of cyber security"). The sheer existence of business card is by itself a huge red flag, unless it is really cool.

For crypto, I prefer cryptocurrency, ecash.

Cyber and virtual are worst (fatf-gafi picked one from this set, which is telling). Any mention of blockchain is also a red flag.

For security, I prefer ethical hacking, penetration testing, it security or simply security .

Ecash is OG, it should make a comeback. However, I've always disliked "ethical hacker." First of all, for even the whitest of white hats, hacking is frequently gray behavior. Calling it ethical hacking feels like asking permission to hack something. Which, to your point, they might as well call it "cyber hacker" because it's lame.

There's no ethical plumber and "ethical banker" is equally ridiculous. So I just like to say hacker and let the cards fall as to the ethics. In Slovak, eticky hacker does seem to be the most understood term I've noticed (for me) unfortunately.

But when I'm dressing up, I use "security engineer" which for me, coming from a classic engineering background, is an apropos term I think.

Ecash now has specific meaning and context. There are currently two ecash implementations, Cashu and Fedimint. They allows users to obtain 1:1 bitcoin for privacy (via blinded signatures) preserving ecash notes.

The origins stem from David Chaum.

Ecash is a privacy and scaling solution for bitcoin.

There are many more than these two.

First federated ecash mint was scrit, way before fedi ( https://raw.githubusercontent.com/scritcash/scrit-whitepaper/master/scrit-whitepaper.pdf ). There's ecash on eth called ZeroWei... Many mixing solutions are based on conversion to ecash notes, either temporary (Wasabi) or more long term (Tornado).

So I would say the meaning expanded, not became more specific.
