If young and employed and little life savings, I guess it makes sense. If any of those cinditions is untrue, I'd call it unwise to foolish.
Yes, it depends if you can recover from loosing all your savings. Although I'm an optimist regarding bitcoins' future I would not take irrational risks that would ruin my life if future does not turn out as hoped. Past performance is not an indication of future gains. Bitcoin is still beta software and not established. It can still fail.
There is no "sure thing".
ya.ya.yo!
