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.
One of the hardest things to know is when to sell bounty tokens when they hit the exchange. I think it's highly dependent of the quality of the project and the hype around it. I currently have a coin whose tanked when it got listed and now it's tanked even more during bearish trend. Sometimes you just have to follow your guts and decide whether to sell or hodl.
