Someone is out there flooding the mempool again. Easy to tell that's what's happening because it's on a weekend (almost always less demand on a weekend).
Not sustainable but good for the miners.
My guess is that it's a bunch of shitcoin scammers who are going to try the bitcoin is too slow and costly thing again.
How much would be the cost of an attack like that?
When bitcoin was forking there was for sure a mempool manipulation, but nowadays I fell that unlikely.
Imho the problem is that when crypto move fast bitcoin is not enough fast, we should implement a better lighting network or bitcoin will never work for coffee or anything besides being a store of value.
