In my opinion, the high price increase of Ethereum as it is today is also very influential on the increase in gas costs or expensive transaction fees. not a few people complain about this, especially bounty hunters in making exchanges that have to incur high costs 
It is true.The price of Ethereum also plays that factor why it had became expensive and it's because of it. But the time will come that the fees will be low again but we don't know when and maybe it's after this bull run.
