However, like everyone else, I don't have any special insight that makes my guess more right than the next guy's.  I could be totally wrong and most certainly am at least partially wrong.  I think good advice is to imagine losing all the money you have in bitcoin: if that would cause you some pain, well, that's OK; if that would cause you to lose your home, wife or business, then you're probably investing too much.
