If you had faith, you had the opportunity to average down from $19 to under a $1. If you didn't run out of money, you ran into discipline constraints. I expect that many did one or the other. Or both.
The brilliant/lucky/late comers averaged up from $1.
Actually it is the shares I bought for under 80 cents that mean the most to me...Believe me those suckers make up for a lot of heartache...and can get you "right"...in no time...already four baggers (the little devils) and to think nobody wanted them...
