Even though I am not a fan of Ethereum at all, we should not avoid ETH just because a lot of scams happen on it. That is like avoiding Bitcoin or fiat because drug dealers and child pornography use them as payment. The reason so many scams happen on ETH is just that it is so easy to create an ERC20 token. You have people now just selling services, to create a token, whitepaper, logo, signatures and all that in a week.
