Don't be in a hurry for your bitcoins to reach their potential value. Will the whole bitcoin economy be worth more than $8 billion in a few years? Many people who understand the technology think that it, or cryptocurrencies in general, will replace a lot of the current global financial infrastructure eventually, which is worth trillions. Will it be a smooth ride up until then? Definitely not. Will it go a lot lower on the way? Maybe. Take a chance if you're greedy, or just sit tight and hold. These forums are full of people weeping about how they were just about the buy back in at $2, $5, $200, whatever. I sold a few at $100 in July thinking it wouldn't see that high again. If you can afford what you have spent on them then hold on to them, if not, sell the bitcoins you can't afford and stop worrying. In the end it's your choice.
