I wouldn't lose any sleep over it. It was a flash crash meaning the price dropped in a second. You would not have been able to actually buy at .12 cents or a $1. The people that did already had their buy orders in prior and truthfully, I would not want to be them at all. I am pretty sure the US government, IRS, etc. are trying to figure out who they were and will be going over their financial records with a fine toothed comb especially since many suspect market manipulation.
