Maybe we think that the current BSC gas is much lower than Ethereum for every token transaction. If we look at the total Ethereum issued now with the previous it is almost the same. Except on the use of the swap platform. Ethereum token transaction fee is 0.001 to 0.002 ETH. If we look at the transaction fees in 2019 it is also on par with now. It's just that the current price of Ethereum is much higher than in 2019. While the transaction fees on the BSC blockchain are 0.0005 to 0.001 BNB. If the price of BNB is equivalent to Ethereum, the transaction fees will also be the same. Regarding transaction speed, it is possible that the current use of the BSC blockchain is much lower than the use of the Ethereum blockchain. So that the network load and confirmation block on the BSC blockchain will be faster.
