There is a huge risk for ICO, but the huge risk is a huge profit or loss. so it's really difficult to become rich here, we need a lot of time and effort to be able to do the right things here in crypto.
It happens always and everywhere. Pioneers in new technologies receive the greatest benefit for their faith and patience, and then comes a large number of people who get much less. In my opinion, this is true. Therefore, to become rich at the moment is much more difficult.
