I look more at ICO as a positive idea about crypto and this will continue to exist, but some people who have a bad mentality use this to steal more investor funds under the guise of crypto. ICO will continue to exist but they must be of higher quality if they want to continue to exist and be accepted by users and markets
ICO is a good business model for attracting money, but just now it has lost its popularity since there are no investors in the cryptocurrency market. when the market starts to move at as a bull then new projects will come again
