Now I have stopped investing in ico until better times. All the ico in which I invested in 2018 are now trading below the ico price or delaying unlock tokens. The only ico that brought me a profit in eth is the XYO Network at the moment.
Having a lot of tokens this year also reached a higher price than the ICO price after completing ICO. For example, Quarkchain, it costs 5 times higher than the ICO price, so is it now, as long as you choose the right project, you will make a profit from it.
