Like most retired guys I have a group of friends that I will fairly regularly meet up with for lunch, dinner, or a few drinks. Last night was one such occasion. We went to dinner and a concert, and we had to settle up what we owed each other. Two years ago I started trying to pay my share to this guy in bitcoin. He thought I was nuts and declined. It's not like we don't talk about bitcoin. He knows my interest, and he even likes hearing about Stacker News, which I talk to him about pretty regularly. He's a sports gambler, so I'm always trying to use @grayruby's territory as an incentive.
He laughs and says he has no interest in money. That's certainly not really the case. He talks about money a lot. It is true that he has no interest in investing in conventional fiat markets either. It seems like he only wants to bet on sports.
Once again I offered to pay my share last night to him in bitcoin, and he refused. It's odd, because he obviously likes to talk about it. He finds it amusing in an odd way.
As a last resort, I used the old NGU on him, calculating his return on investment if he would have taken me up on my offer to pay him with bitcoin how he would have more than tripled his money. Nothing. Not even fiat FOMO moves this guy.
It's a strange situation.
Edit: I should have added that next week is his 70th birthday. Maybe that matters?
