Everything seems to indicate that the ICO as a business model reached its peak at the end of 2017, when we saw an explosive growth motivated by the speculative wave that took an immense flow of money to the market, which led many opportunists to look for a slice of the cake presenting banal projects and lacking utility.
But the current crisis has unmasked many of these scams, which has led to the loss of credibility in this business model, so the new ICOs are struggling more and more to achieve their capitalization goals, which may increase the difficulty of the bounty hunters to obtain profits in the usual bitcointalk campaigns.
This is a nice description of what happened, many people have lost money through icos and while there are definitely honest projects out there once you lose money and realize that you invested in a scam the chances that you invest in an ico again go down dramatically, and when we consider the crisis in which the market is immersed then we cannot blame people for not investing in icos right now.
