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?
I don't think it is possible to have some bodies, who will be responsible for it. Unfortunately, everything has its pros and cons. So in crypto cons are great amount of scam. The only thing we can do is be more careful and do researches before investments and also help newbies not to do such mistakes. So as a result it can decrease scam projects.
