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?
Each person may have a completely different situation in life. For some, it's the only way to survive, these coins do not sell it on the exchange, and on the Delta. And believe me, he would have wanted to sell it at a higher price, but he had no other choice. I talked to these guys, they say that they sold to have money for food.
