I'm really sad that Ethereum isn't in good shape presently because of its annoying transaction fee, this will eventually affects the project from reaching a new all time high since DeFi is the big part causing the surge.
You can't be sure of that, most things that are thought to affect cryptocurrency market have not. Like people througt the problem with covid-19 would affect the market but it has not and price has been going up. So for the fees on etheruem, it won't because etheruem has a large coverage and use value.
