i'm thinking that crypto is the most magic-resistant currency

you can use a spell to duplicate gold or paper money

or create an imitation/illusion/forgery [counterfeit/fool's gold]

you could even magically teleport/steal the money

but with bitcoin:

duplicating does nothing, it's just creating a backup

imitation won't work since a computer is checking the numbers, not a human

teleporting _could_ work if you teleported the seed etc, but that's a lot harder than just plucking a few dollars from a generic cash register
