I do, actually. I never said there was a mechanism that induces swings--there doesn't need to be one. The users do it through speculation, just like with any other asset, only it's worse with Bitcoin because it isn't tied to anything of real value, even theoretically (unless you think wasted CPU/GPU cycles are valuable). Being "democratic" doesn't magically safeguard against that.

I'm not a fan of the fed and I think some sort of decentralized currency would be great. Bitcoin was a good idea and I'm glad we're experimenting along those lines, but it's a failed experiment. It's never going to work as a mainstream currency. Maybe some future iteration of the cryptocurrency idea will be the solution, but Bitcoin ain't it.
