Yes, it is true that gas fees are one of the weaknesses that Ethereum has, because of course we also want lower gas fees, and I think that is the nature of those of us who want to pay cheaper financing.
It is not impossible that they will have competitors who might overtake them and now there are also some narratives that Solana will overtake Ethereum. Even though this is just a narrative, it is still something that is not good for them.
Yes, gas fees will make investors switch to those with cheaper gas fees. and until now ethereum has not found the right solution to its problem. As you said this is a threat to ethereum because BNB and Solana offer lower gas fees.
Maybe they will try to find a solution to the gas fees on their network. Because for small investors, they might think twice about investing. Even though they are only small investors, they will also be very influential.
In my opinion, like it or not, they also have to adjust this, because it cannot be denied that cheap gas fees will attract investors who bring small capital. Especially when traffic is heavy, we know what the gas fee is like.
