I think you can keep it as an option. People here suggest quite rationally to increase discount because indeed on KYC-free marketplaces like Bisq or similar Bitcoin always costs a bit higher.

It is in the nature of sound money to disincentivize spending but if you have product of great quality i do not see any problems in having more bitcoiners as clients. For many of them it may be actually more convenient to use Bitcoin at some point.

Just do not stop.
