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 .
I guess people are dumping their bitcoins because they are in need of money, and maybe some people are thinking they might lose their money for the price of bitcoin that ate dumping. Like me although I am planning to save and hold bitcoins there are instances that I will sell some for I am in need to.
Sad to say but this is true , For me bitcoin is an investment however due to unforeseen circumstances I am forced to sell some of my bitcoins due to personal needs , most of my extra money was on bitcoin so I dont have any choice but to sell some of it even thou sometimes I'm still at lost.
