I know someone who sold shares, to use as a 30% downpayment for a big house, and I suggested he put it in bitcoin (around $18k, at the time, right before this last climb), and then he could ride Bitcoin up, sell enough to pay for the house outright, and still have the rest as savings.

He just scoffed and put the entire 6-figures in a big mortgage that he'll be paying off for 30 years.

I never bring the topic up, but he'd be independently wealthy now. 🤷‍♀️
