Comparatively I still believe they're more trustworthy than the fiat currency ones. But that doesn't really matter in practice :

As long as your assets are in the cryptocurrency itself, and you're happy with that, there is no need to trust any intermediaries at all.

You can have local and international money transfer that safe, final and trustworthy. Money, of course, meaning bitcoin (or ether, or ...). That's a valid usecase.

That's the key.
