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?
Depending on the development of the project, because if the token has a plan it will be released in a large exchange, say top10, maybe a cheap token is an opportunity to buy before the price of the token is pumped.
