Scamming your own fellow human being won't do you any good and its a criminal offense too that can get you jailed, the choice of good and bad lies in one's heart and you are the one that can make the decision, why don't you spend your talent on something else, something that can make you happy? People aren't that stupid anymore to invest in project with no use cases
Well,,, this place is full of people who want to take advantage of others. It is human nature more than anything. Greed and selfishness. But you mentioned something with a point, about being criminal offence. People get away with crime a lot especially white collar which ICO and token crimes basically are.
Until the law also punishes equally those who commit financial crimes as a normal thief who steals a few dollars, we will always see this happen.
