What concerns me is that I don't think this is motivated by "it'd be a good idea if we only allowed coinbase customers to pay in crypto". This smells of "we'll save more money by not taking the heat over KYC regulations than we will lose in customers".

If that's true, expect this to start happening in all US based payment processors, and then it'll spread across the globe.

I'm going to wait until I have personally set up a BTCPay server before I personally recommend that solution. Hopefully that will be something that rises to the top of my pirority list soon. 🤓
