Plenty of central banks seem interested in launching digital currencies. For me the main selling points of cryptocurrencies are programmability, easy international transactions, and potentially easy micro-transactions. Personally I don't care much about the fact that they are decentralized, and while I'm happy for my bank to see my transaction history I'm not that keen on having it public.

If I could move my savings into a digital currency provided by a central bank I'd do it today. Bonus points if it can be stored in something like special drawing rights rather than euros.
