Digital currencies will exist as an instrument to hedge against currency fluctuations, commodity manipulation, and to let you deploy liquid money into assets with calculable appreciation/depreciation rates. National currencies are much less volatile than Bitcoins have shown themselves to be. In the future, we may not be using bitcoins, but you can bet we're going to be using coins made of bits. I think we can agree there. "Bits" have nothing to do with it. It's this: Money pre-1800: metal (usually gold or silver) that can be used to pay taxes and hire killers to defend land. Money 1800-2075[?]: debt of large institutions, with equity a small player. Money post-2075: access to talent (the new limiting factor on getting ideas into implementation). We're starting to see that. I put that at 2075 because people are very conservative when it comes to money, so even though that will be the definition of wealth decades before that, I think it will take a long time before we can come up with a reasonable talent-based currency. What would the proof-of-work model be? It's hard to say.
