It is very sad. Currently, many traders have opted for Bep20 due to low fees. Lately I have seen that the fee has increased a lot. Above about 1$. Which used to be 8-15 cents. There are many small traders who are facing losses in this. Maximum low capital trader does not swap on Erc20. If Bep20 increases in the future, maybe they will move away from Bep20.
At least BNB gas fee is still far lower than ETH gas fee. The rising price of gas fee in BNB is because the BNB coin price is rising.
The BNB gas fee is not too high, which is only around 5-10 GWEI per transaction, see here :
