How long do you think bitcoins will be around? What's your guess on the most they'll be worth? I personally think they will stick around for a long, long time. I'm guessing around five+ years, if not ten+. I think the only downside to them is you should be able to buy them with a Credit Card from your wallet, but I can see how thief's make that difficult. Another flaw is you can't reverse a payment, say if someone hacked your account and took your coins there's nothing you can do. As for how much they'll be worth, I don't really see them ever being worth more than 1,000$, but at this rate I'm sure they'll at least be worth around 800$ in the future.
