I have never invested in any ICO. I saw that most of the token / coin after being list on exchange was depreciated by more than 50%.
You look at your feet but don't look at the sky.It is obvious that the price is cheaper after listing.But if You build a long-term strategy,you just have to wait not for the first listing but for the working product in which you invested.That's when we can talk about profit or loss.The price of the first listing is not an indicator.
