The idea of holding an ICO is very good in itself, but due to the fact that large amounts of money can be collected for ICO projects and that everyone is allowed to conduct it, this activity attracts a lot of scammers. Therefore, it must be regulated. Either create self-regulating bodies, or it is necessary for it to be regulated by state bodies. Then the ICO will regain its popularity again. In general, this activity is very useful for cryptocurrency.
