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.
In my opinion The reason of increasing BNB gas fee is increasing BNB price and increasing transaction day by day. Millions of transactions are forcing gas fees to rise. Many people are raising gwie to complete their transactions quickly. And it is forcing gas fees to rise
