How do you know ETH gas fees will be lower in near few months? I don't think it will happen soonTM, so I believe BNB's rise will go on in next couple of months. Even if they fix ETH gas fee problem it won't be near as BNB's low fees. People get tired over 100$ swaps so they switch out. ETH swap fees won't be 1$ anytime.
I agree with you mate, seeing the way things are going with eth, I also don't think the high transaction fees that has been the major problem with the blockchain for over a year now will come down anytime soon, take the London upgrade that just happened on August 5th as an example, one would think that such upgrade should help bring down the gas cost a bit, but rather, it even pumped the gas cost higher than it was before the upgrade kicked of, so sincerely, am not sure the gas cost on eth blockchain is coming down anytime soon, and this also is a good news for BNB holders as the price is likely to keep going up since there are lots of demand for it.
