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 .
Those people don't know how to wait. Let's just say that they badly need money, but is it their main source of income? I feel bad for them.
Or maybe they are afraid that their coins will drop to the lowest. This is bitcoin, the prices fluctuates and it is normal. They just don't know how to wait.
