No, I don't he is buying. He won't even touch gold, why would he buy bitcoins?
Man now that I have this information a lot of stuff becomes more understandable all at once. The guy doesn't understand gold either. Well then yeah, you'll never get him to buy bitcoins then. It's no use

Gold gets dug out of the ground in Africa, or someplace. Then we melt it down, dig another hole, bury it again and pay people to stand around guarding it. It has no utility. Anyone watching from Mars would be scratching their head.

My dog also makes this "I'd be scratching my head if only I had fingers" face when he sees me doing human stuff that he doesn't understand, such as cutting the branches of a tree standing in my path or other stuff like that. For sure dogs don't bother doing such stuff... yup that's for sure... :-/
