My neighbour playfully ridiculed me back in 2017 when my coins had dropped from $4K to $2K, he hadn't remembered that I'd bought most of them at $625, but I didn't say anything back then.
These days we have a mutual neighbour who is in her late 70's. She is constantly fascinated by Bitcoin and asks me questions all the time.
He doesn't enjoy listening in.
I think it's only hubris that is preventing him buying now.
He's a nice guy and we get on well, but I tend to avoid discussing Bitcoin with him these days.
