Wow, I hadn't needed to send Bitcoin out for a while and today took me by complete surprise. No way I would be paying the suggested 66 sats or so, so I thought, yeah, let me just send 1 sat/byte and see how long it takes. I can always RBF.
Then I saw a new icon I'd never seen before on Electrum next to my tx, clicked it and it told me mempool rejected my fee as there are hundreds of thousands of other txs with much higher fee (I'm not quoting, just paraphrasing from memory as I didn't take a screenshot).
RBF'd it. I did badly want to experiment with this non-urgent consolidation though...
P.S. Funnily enough, just this morning I was wondering what happened to ordinals, is that possibly part of the cause?
