Good example of how stupid current lightning implementations are re: fees.
This tx paid $38/89,907sats to spend a single anchor output at 497 sats/vbyte (6x higher than necessary to get the tx mined), producing a single output just 6437 sats in size.

It's not a CPFP: the commitment transaction was mined 3 days before the anchor output was spent.
It's just an idiotic implementation that wasn't willing to forget about the anchor output; I know LND does this. The channel itself only had $2540 in capacity, so that one transaction spent 1.5% of the entire capacity on fees.
The main problem with lightning is that I can’t understand it. Maybe even lightning won’t be the retail level stuff and it will be service. Medium sized players can make settlements with that but it might be still too complicated for coffee stuff.
Upward and onwards to Layer3! :)
