it is a bet on the future. I'd invest some money, but only as much as you can afford to loose. Think: where will it be in 10 years? Do you believe in it or not? I know someone who invested when it started bc he is a tech guy and believed in the idea - he is rich now and quit his job. That won't happen any more but there is still a chance to make good money. But be careful it is highly volatile. I invested a year ago, lost more than half my money, but it's all back now. Let's see where it goes.
