In the abstract, dollars, euros and any other hard currency isn't really worth anything. Currencies trade against one another and are issued by stable governments. People around the globe have faith in the dollar mainly because the US is a stable country with a strong economy. Bitcoin has none of that. The only thing it has going for it is that its a huge market that anyone can participate in. You don't have to buy an ounce of it, go through a stock buying service, etc. There's a kiosk at my grocery store that sells it. Had I gotten in on it early on, I'd have gotten out a long time ago.
