The following one, seem to be the right one: Desktop file would look then: Categories=Office;Finance;Cryptography; At least that's the one I like (whether that counts or nor not) But indeed Utilities for miners should be taken into account as well. But that are very likely not as much as there will be wallets (there are so many of those (wallets), there must be really 1 category to seperate these from all the other goodies).
