I saw 70-80% ico are scam which are not reliable .they do smart work and making projects by invester and advisers and after not giving token ,making scami .what to do with them. Have you ever fallen in scams ? I am fallen some time .
I think that if you have been engaged in crypto currency for at least one year, then at least once during this time you had to deal with scammers. Currently, there are too many such projects. Investing is dangerous. Unless you are 100 percent sure that the team that stands behind the project is real and professional. It seems to me that this should be regulated precisely at the level of legislative acts. And not one country but many states. Otherwise, we all will face this for a very long time.
