Bad investment

Home was worth
$400K and he only got
648 BTC which is only worth
$259K at todays prices
He basically gave his house away super cheap and should be sick about it

What do you mean by *should*? Why don't you think he is happy to own so many bitcoins? Maybe he is living on a tropical island and knows his money cannot be unjustly frozen or confiscated by a civil court lawsuit. Maybe he is simply confident in Bitcoin's future.
