Fraud that happens to ICO, STO, and IEO, I think it will be difficult to eliminate. Because there is no real regulation can set good about the project. Indeed in 2017 many projects were successful and at that time Crypto soon became popular.

Yet many irresponsible people have found a weakness against the ICO project. So they created the ICO just to commit fraud.

Now it is difficult to restore investor confidence in the project. Maybe the process can not happen quickly and need a real project can generate many advantages such as the year 2017. So slowly investors will return.
