The question is, will Bitcoin last like gold, or fade like tulips? The Foundation for Economic Education produced a neat video that seems to suggest Bitcoin is here to stay, at least when you look at what properties a sustainable currency needs. In fact, Bitcoin looks a lot better than the greenback. It's uncertain whether it is a fad or the way the world will trade goods and services. But, after watching this, you can't help but have a lot more faith in Bitcoin than in fiat currency.
