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.
Honestly speaking, Ethereum is the major problem that we have in this cryptocurrency industry, and truth must be told. This is why I so much hate Ethereum, because they are the one that gave chances to some of these scam projects. They sold innocent investors out to scammers because of the little smart contract fee they are collecting from them, and i will say that ETHEREUM is really the biggest scam as regards their smart contract.
If only they were following this products up diligently like the way Binance is doing, but no, they will rather prefer to keep approved all manners of shitcoins that keep proposing to them without doing their due diligence first. I dont know about the chain you mentioned here and I will look into it, but I still respect the tactics that Binance in using in accepting their own IEO projects, which is why you may never see any shit project coming from Binance chain.
