I have a transaction that I set at around 13 sats per vbyte within the last few days, and so I already have an understanding that it could take several days and maybe weeks to clear.
A few months ago, I had some others that took a while to go through when I set them at the lower end of the range of what had been being cleared, and surely I can see that there remains a bit of a gap between my transaction and the ones that are currently clearing in the 20-ish sats per vbyte, as you mentioned.
Wen clear?
hahahahaha
I don't really care that much.. I set my fees in that kind of way just to watch it, but if I was transacting with a stranger, probably there would be a need to set it in the 30-50 sats per vbyte range in order to NOT piss anyone off or to risk losing reputation/credibility.
My transaction cleared minutes after I published this post. It went up from 150mb from tip to the very top immediately. Perhaps a bug in my wallet software or something as I found no evidence Ordinals or any other NFT spam intensifying.
