If you're going to sell stuff and go "Bitcoin Only" as payment method, I'm -never- giving you any sats if you generate your invoices dynamically based on the BTC/FIAT rate.

The only way to have any credibility when going "Bitcoin Only" for payments is to have a price in BTC, period.

You can always adjust it manually when markets are volatile and (once a month or so), but otherwise pegging your BTC price to FIAT is just virtue signaling, so there's no point to not also allow fiat payments.
