As a Bounty hunter I once made a mistake by selling tokens from Bounty that I received in a small market for $ 250. After 20 days the price of tokens that I sell is worth $ 1200. So the conclusion if you want to wait you will get maximum results. Believe every ICO project will prepare a good market in the future.
Yes, It's true. I strongly agree that you should not sell tokens at once, but you just have to wait, if the project is worth it, then they will definitely go up. I have done it. Be patient and wait.
