It's a new currency, it would be illogical to assume that the price of bitcoins will be wildly irratic as it catches on. The one thing I know about bitcoins is that I don't know what they'll do. The volatility makes bitcoin trading attractive to me, also, you can only lose what you put in, the trading costs are ridiculously low, and I started my account with $100 bucks. Initially I lost value but I just waited it out and turned $100 into $130. That's a huge return in less than a year. Obviously this is more of an exercise, I wouldn't get stupid with how much I put into bitcoins, the whole thing could collapse tomorrow.
