Cyberpunk doesn't necessarily have to do with crypto, it can just be internet and VR and being a rebel while being jacked in to your nine-CRT set up in your neon-lit basement techno club.

Cypherpunk refers to the same basement techno club but the freedom and rebellion comes from the privacy and inviolable secrets enabled by cryptography.

edit: Better comment below me, cyberpunk is very much set in economic dystopias, and the rebels are tech hackers.
