Sure it's volatile but there are truly innovating companies. Gulden for example can transfer directly to iban accounts. You can also directly get Euros from them on their own website. Shops are starting to accept Gulden locally. These are the projects to follow.
What's the point behind Gulden, though? Why do I need a cryptocurrency for anything they're doing? Do they allow anonymous gulden -> IBAN transfers? If yes, that'd be a unique feature but also one that has obvious potential for misuse and might not go down well with financial institutions and regulators.
