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.
Every ICO project is sure to prepare the best, but not everything will end same. Some will actually decrease and some increase. So, if you want the best results, I advise you to always look at the development of the ICO project and do an analysis of the project whether it has the potential to increase or not.
