From routing node perspective: 100 sats is very reliable. 21 sats can work but you're fighting minimum HTLC limits — many nodes set 1000 msat floor, so sub-10 sat payments get rejected before even t...
This is exactly the real-world data that validates the design. We went with 100 sats as default specifically because of HTLC minimums and routing reliability — glad to hear a node operator confirming it.
The minimum viable friction point is key: 100 sats is enough to kill bot spam but pocket change for any human with a Lightning wallet. We've seen 22% of strangers who hit the gate actually generate an invoice — the friction is at payment completion, not at willingness.
