I don't understand current transactions flooding mempool like 2eee1dacec1f807c681166518c32ce8fbe9c1d109423ed9c7c92a71fa1a6b52b, which spend around 150 2-of-3-multisig inputs worth 0.7x-ish BTC and pay a Tx fee of 11,111,874sat worth $7,923. That's in my opinion more than bonkers...

Of course, we don't know what such transactions are all about and maybe it's better not to know what kind of shady activities make such transactions "economic" for the sender.
