Don't have a single friend who uses any sort of cryptocurrency, let alone Bitcoin. I also definitely do not like the idea of cash by mail, too risky even with an escrow involved.

You can make Bitcoin friends. That's what I did. Build your network. Go to meetups. Build trust.
Lol not when you live in a rural small town whose populace is overwhelmingly elderly people and farming families. Unfortunately, I don't have the time to spare on going to meetups even if there were any nearby (there aren't). As I've said in the past, I believe in the tech behind Bitcoin and I believe in its goals, but it just doesn't work for me, personally. Not at this point in my life, at least. I'd love for that to change, however.
Whenever you get the time, we'll be there waiting. Good luck to you, sir.
