What would you do if the market crashed 50% tomorrow?

Only theoretical, what would you do if you woke up tomorrow just to see that the price dropped more than 50%? A real flash crash.

Would you - buy more and be optimistic it will bounce back? - hodl but with caution because of such a fast crash? - decide it was a bubble after all and panic sell? - throw your coffee mug at the wall? - stare at the charts for the whole day in disbelief? - just assume it must be a bug with the charts? - something completely different?

If been always asking myself how I would react. Probably still try hodl, but you just never know what you will do when emotions come into play.

Such a crash would show who the real believers, who are in for the tech, are.
