Years back, ETH transaction fee was a penny, now look at it and it's volatility. Shouldn't we focus on polygon chain now, make judicious use of it as for some developers before it turns out to be what we see in ETH transaction fee today. Though the traffic there is low but this how erc-20 chain also started. Nobody knows it's gonna be what it is today
One can say in a way, it is not the fault of Ethereum blockchain for the gas fees to skyrocket like that, Ethereum is housing a lot of projects and DApp, so in a way it is expected, and which is why the team are trying their best to solve that issue hence making their blockchain more scalable.
BSC network is growing and if it maintains the growth, it will get to a point the gas fees will start increasing, and same with Polygon, now when such happens, will it mean the two blockchains are not worth it again, I don't think so, what will be needed at that point is more implementation and improvements.
Lastly, Ethereum price is increasing hence it is most likely to reflect on the gas fees as well, all these, shows the signs of a growing blockchain which is good, because if it is not growing it will be neglected. Moreover, when ETH takes care of the high gas fees, I wonder what most blockchains will do, because it will outshine them even more.
