Yes, good point - I forgot about the storage coins. Maidsafe is particularly interesting, I think, because the technology behind it has been in development for so long and the main developer, David Irvine, is a serious heavyweight.

I also like the look of Zcash in the anonymous coins department. In the longer-term with anonymous coins, there does seem to be an extra risk that the gateways back to fiat will get closed off for regulatory reasons. I can easily see a situation developing where the authorities say "OK, you can run an exchange, but if you allow coin X, Y or Z on it, we'll shut you down".
