then why don't you start from yourself?
that is the problem with most cases who ask about adoption, everyone should start from their own. start accepting bitcoin as payment, start asking people to pay you as payment (like asking your employee), start spending your bitcoin wherever you can, start asking others to accept bitcoin payments.
From the sound of it, he’s not a practitioner, just someone who works in healthcare. I think my employer would laugh me out of the room if I told him to accept Bitcoin.
I’ve definitely read about some sole practitioner attorneys or small law firms taking BTC. Not doctors, though. Healthcare is very corporate where I’m from — not likely to accept BTC. But the fact that I’m seeing acceptance among other professionals and also for things like real estate tells me that adoption is ramping up.
