As I have noticed these days, when the ICO hasnt finished yet and the sale was still on going, the bounty tokens has already been distributed and also unlocked they sell it immediately on forkdelta or etherdelta for a much lower that ICO price, in which it could greatly disturb the sales in tokens. As for you the investor on that token, would you panic when you see that the tokens you own already selling at much lower price?
I was not felt like panic and Yes I sell all my tokens from bounty reward which it has have enough value for me and I can not wait higher value because of my necessity so I dump it all , although some times the price will increase from nowadays but I have no regret with my decision .
