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.
Currently, the greatest majority of coins lose up to 80% of their value after they are listed.
So what you did is actually that you tried to minimize your risks and there is nothing to blame yourself for.
