Did you hear about that one, "buy when there is a blood in the streets"? Times like these are the best for investment. Not when we were at $1,000 and everybody were buying. Interestingly, when we were hovering about $700-800, everybody begged for cheap coins, now when they are here, nobody wants them.
Bitcoin is still just an experiment and can fail. If you ask me, if we can't have a consensus over a block size increase, then we need to fail, since there will be many more consensuses to reach down the road that might be even trickier.
But if and when we reach it, price should take off to at least a pre fork level, $300. It's up to you to decide. Do a research and listen to yourself.
