Yep, as a payment provider I can tell you my customers (merchants) are super impressed when they see that 0 sat fee in their customer’s wallets. They are super price sensitive. Last time we tried with on-chain transactions we got very negative feedback when the tx fee rate spiked
This is my impression as well.
I want to push lightning adoption as far out as we can.
Two factors (besides merchant adoption) are critical for this in my opinion:
  • fast (like in < 1s fast)
  • cheap (ideally free) payments.
