Is there any posible way to filter who are going to make an ICO to be able to know if there are scam or not? And is there any bodies of law that would be able to punish them once they turn into scam. And what punishment should be given upon committing such the crime?
In General, each country has its own laws. But here the situation is a little different, the scammers know how to bypass many laws, while remaining anonymous and thereby mislead the society. I believe that until a single system of tracking and registration of ICO projects is created in the world, fraud will flourish. But unfortunately, geopolitics at the moment is not yet ready to make such global decisions.
