That's a risk to invest into an ICO, but your money can be multiplied in such investments. If you carefully analyze project that you are going to invest in, you can minimize risk.
First of all investigate team and founders. Founders should be real persons with successful projects.
There are a lot of things to consider when investing, therefore we need to work and spend time to know the project itself.
Based on the current coins standings right now, we have seen a lot of coins that are successful and giving their investors a profit of x10 which is still
conservative because I have seen some grow more than 100 times from ICO price.
