The only negative thing i caj think about is that if a great number of people gets scammed a lot of times and happens to lose a whole lot of money due to this scams, then i think this will cause them to spread a lot of negative things not only about etherium but on Bitcoins also and the whole crypto world as a whole. And this will really make other people looking into jumping into the crypto world turn a hundred and eighty degrees away from crypto currencies and help spread the negativity which can the be very bad for the crypto world.
