Everyone must have an exit switch in case the kaka hits the fan and Bitcoin drops arse or if Bitcoin hit a certain price match and it would make life substantially easier to cash out.  Just wondering what would you need to happen to set that switch to cash out ASAP.

Would it be a low price?
High price?
Regulation?
Strong International/National economy?
Personal financial situation?
Stable price?
Massive price instability?

Give everyone an insight to what you think would make you push the big red button and call it quits.
