ICO, STO, IEO all use erc20 a lot but in fact I also hope that bep20 from Binance will become a real competitor to erc20 from Ethereum.
Due to the increasing number of ICOs, there are also more frauds and this is a bad image for Etherercum.
But as the OP said it is true that erc20 is the king of ICO, good job!
