wow
that's incredible.
i couldn't imagine a universe in which my dad would listen to me. it's awesome that you have a relationship in which you can share things and be receptive and open. especially something like bitcoin. i find that people are either really open to it or really closed off to it.

was this something gradual, over multiple conversations?? 

 It took years to convince him. Why doesn't your dad listen to you? 

 oh, my dad was very opinionated; it was difficult talking *with* him about much, especially in disagreements. it was more or less just being talked *at* if we talked. but he was like that with everyone as far as i can remember. there was never really a point in which he'd be curious to understand a different view.
