When investing in an ICO the most important thing is to do a background check. You don't wanna invest in an ICO which is going to fail. The ICO will succeed if their team, investors are competent and they are here to actually solve a problem. There are many examples of these ICOs but let's take Investy (
https://ito.investy.io/) as an example. They offer a decentralized trading platform for investors and traders. They have an "expert system" which blocks operations committed maliciously. The fraudster is deprived of the opportunity to work via the platform meaning the investor's money is safe. They have an ICO now, offering 44% bonus when buying tokens.
