I will check this weekend to how cheap it could be.
Already the fee went down 16sat/vb and that could be the cheapest for near term cause there is much TXs that left below this rate which makes it not really possible to go beyond this fee rate at the moment.
But definitely 16sat is a lot cheaper and congestion due to runes cleared pretty quick than expected.
I checked mempool.space and noticed same thing, for being It has never been this low right from the second week of halving, even as halving ends it's not still that cool making transactions except for this evening. Sincerely the runes really came to cause serious distraction and attack on the bitcoin chain.
Yeah the memepool has indeed been really empty lately, which means that the volume of transactions on the network has been relatively low.
We can indeed consider this to be abnormally unusual, especially after considering that the just concluded halving was supposed to typically increase the number of activities that goes on in the network.
Saying that the Rune token airdrop was one of the reasons for this unusual behaviour in the network because it has really caused a lot distractions and congestion on the network making the memepool to be relatively empty and leading to transactions being slowed down and also paying high fees for a single transaction.
