Yes, its because of the fee's in binance chain, imagine how big the money you can save with binance, i have tried transferring small funds the fee is so low, and the transaction is fast, while ethereum is the other way around high fee's, and takes longer to transfer, I think binance and tron are the cheapest fees, no wonder binance is taking the spotlight out of ethereum, and if they can't address that issue you can see more movement upward with bnb
