Participating in any ICO always comes with a risk. There is no safe one,everythings come with a risk. We are actually gambling whenever we participate in an ICO. We are betting if that ICO will be a success or not ( with money, with our investment).
What we can only do is to improve our betting chance through various research. Background checking and project analyzing are the things we commonly do. And this is almost right all the time, there are just some cases where in scammers also got good project and good team so please be careful. Trust your instinct sometimes because not everything we see is real 😊
