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 would not, according to my opinion it is because when the time passes by, its pricing will increased for sure and surpass its presale price. I believe in holding for long term and I also believe in the icos which is very trustworthy, it helps the tokens to be an expensive one.
