ETH gas fee became high because of it's current price, the fee increases it's value as the eth price increase. Not planning to promote, but many people said that ADA(Cardano) is trying to do something to replace ETH.
I don't even believe it to happen. BNB and DOT are better than ADA. I do believe if ADA has no potential to replace ethereum. The majority of ethereum users who have been deciding to exodus to the another blockchain has been choosing BNB over ethereum. That being said if ADA is not so popular as BNB or DOT when you are seeing from the result of massive exodus.
We must see that based on the reality dude.
