All eyes are on the BNB due to the increase in Ethereum's gas fee. Thinking about the beginning, it can be understood that the BNB's gas free is increasing day by day. Although I don't know the exact reason behind it, the curiosity is there.
Bnb fee is still very liw as compare to Etherium. I think bnb gas fee is same but due to increase in price the $ amount is increased. In future uf more people will adopt it price will increase and will affect directly gas fee.
When Bnb price was 43$ its gas fee was approximately 0.02$ and now 0.1$ fir transferring.
