As for me, last 4 days ago I also made a Bitcoin transaction like you, the charge for what I did was also 5$, I also thought of reducing the fees, but I immediately thought that the transaction I would make might not go well so I let it go the fees are only 5$ instead of bothering me because that's exactly what happens at those times because of the nft ordinals in blockhain.
I also found out that most of the people who tried to reduce the fees did not succeed, but instead waited for a long time before they were able to make a transaction again with high fees. That means there is no use even if the fees are reduced or adjusted.
It also took me 4 days to be able to make another transaction with higher fees. I don't use a wallet, which supports RBF service. So I had to wait till the transaction was dropped out from the mempool. Then I was in need of some money, so I had to use the high priority at that moment. Cost me more than $6.
It is getting crazy day by day. Does anyone know when this will cool down? Today's high priority transactions will cost more than
618 sat/vB.

I have to think they want to see how far they can drive price downwards.
