ICOs are investments so do not consider it as something that you will just wait and have your money increased over time for sure. Your money may go to some scammer or some excellent idea that will change the future. Study well and do not get persuaded in a few minutes.
And most of all? You have to believe in what you invest!
All the aforementioned ICOs are excellent, I couldn't agree more. I personally went with ZEN PROTOCOL
Good luck!
