Define wrong ICOs? this actually leads to a good and most appropriate investment. But there will always back to investor, we cannot judge wrong when others maybe say true. And like kryptqnick say people invest is not for losing money. So they must be do their own research before investing.
Because many ICO are very promising and have a really good platform. Investing in ICO is like a gambling because we didn't know will it be successful or not. So taking a risk is part of the game.
