Do you have to explain what crypto fraud is? Many people made crypto and failed during ICO sales. Then there are people who offer the same concept and then succeed. In this case, how do you judge?
Second, there are projects that look good and are successful in ICO sales, but they cannot work on updating so the project dies. What is a scam? in the second case, we will never know that the #DevelopmentTeam will be able to bring the project to work according to roadmaps. So, I think all have opportunities as fraud and we won't know the project is running to the end or death.
