Seeing how old this post is, I am sure some people might want to reconsider...it isn't going away and the black-market thoroughly embraces it. IMO, it's dumb but I would invest if I had the extra cash and sit on it for 40+ years.
It isn't going away, but it is being used more as an investment vehicle and less for its intended purposes. There is also an on going fight between different crypto currencies and how each one works. The concept won't go away but I think we are still far from knowing which currencies will still be relevant decades from now.
