With huge capital, ICOs have existed for a long time and done many things. But in 2019 with the strong drop in cryptocurrencies, the ICO was greatly affected and it is dying.
I have not seen ICOs doing anything in this market in the past. They get huge amounts of money from investors but they don't develop the project the right way, and until the end the projects become scam and die. That's why so far no investors are interested in ICOs because they already know what the end of those projects will look like.
there are actually a number of successful projects, but indeed the numbers that make it a little invisible and the project was only able to reach 50-100 in rating. and the reason investors leave ICO is because of the many uncontrolled frauds and also projects that only seek profits in the beginning without making any further developments. most of the ICOs are only successful at the beginning after a number of roadmaps have been exceeded, the team will leave the project development
