Don't be stupid in understanding this, my friend, many years ago the price of ETH was still very low, and even the same as the current price of Polygon, now try to imagine if the current price of Polygon is the same as the price of ETH now, will the transaction fees also affect you? consider cheap? you have to be careful in looking at this because spending the amount of the fee can also be measured in dollars and can also be measured by the amount of coin prices that are deducted when making transactions.
The consensus mechanism it's already different in the first place mate, I'm not an expert though but why Ethereum gas fee it's keep Increasing because the total transaction was rised more than 10x comparing to when it's launch and it was using
PoW where the fee will be adjusted by the miners, difficulty and many other things so far i know where Matic (Polygon) was using
PoS mechanism so the fee it's more likely going to flat same with BSC or other PoS Altcoin. Fromy my perspective Polygon so far is the best Layer-2 Alternative and the fee will more likely will not exceed $1 since it's using PoS if there anything wrong please correct me.
