If we start counting all useless tokens in crypto space you will notice that most of this useless tokens are running on erc20 block chain ,many good altcoins ive came across have separate owned block chain and they are plain better, I guess the reason we have too many shit altcoins in crypto space is because of the flexibility of erc20 ,making it easy for unprofessionals to build there useless tokens.
We have some good altcoins that are running on erc20 but you will see then moving to their own block chain later on or it will be included in their roadmap about the future swap.
The reason why I like tron block chain is the ability to get rid of fake tokens running on tron blockchain if ethereum can do this it will help a lot.
My answer is too many shitcoins are based on erc20.
It has long been clear to everyone that the Ethereum platform is a collection of any shitcoin , I think it is not necessary to literally perceive that the future is behind this platform , for me this platform is purely for speculation designed for this coins.
