In your opinion what are the reasons that let someone start dumping his bitcoins and walk away ?
I personally (and this is just my opinion) that it's more panic then simply his need of money or something else , as we saw on the BitcoinXT last time , people started to panic and simply sold their bitcoins and that caused a drop in the price .
The person who needed money to pay bills, medical emergencies, or just quick money, is probably the one who will dump his bitcoin. I think the need to understand very well what bitcoin is will help not to act hastily.
