Currently ERC-20 popularity is very low due to high additional gas fees on the Ethereum platform. If the gas fee was lower, the popularity for it would increase several times more than in the past. Especially most of the projects of BSC20 platform projects are getting more success, that's why all investors are more interested in this BSC platform. If the amount of gas fees on the Ethereum platform is low, then again the popularity of the Ethereum platform will increase.
