Now decentralize exchange are very popular. Usually all DeFi exchanges on Ethereum blockchain. Yetucoin is on Binance Chain. It is very interesting.
There are so big commissions on Ethereum blockchain. That is why I think the idea of exchange on Binance Chain is good. Commissions will be less. Also BNB is growing.
I agree with you that a Binance Chain becomes a good alternative to Ethereum. For traders in DeFi exchanges on Ethereum blockchain is not profitable to pay so big commissions in ETH.
