I don't think he had that amount, I don't think even 1/10 of that claim but at the same time why the hell must anyone owning larger amounts of bitcoins be the talk of the town and make the headlines of every news like rappers do when spending money around? Take a guess, how many people have heard of Bernard Arnault? Well, he is richer than Musk but I don't see him twittering all day long!
Maybe a month or so ago I read that he became the richest man in the world, and there was even a rumor that he had something to do with investing in cryptocurrencies - which he denied. Fortunately, not all rich people are eccentric psychopaths who play on social networks all day, and receive billions of incentives from the state, which they present as their business success.
If Popescu is really dead, he should be allowed to rest in peace - and if he had a certain amount of BTC and someone important in life, he must have made sure not to take his wealth to the grave. He obviously had a lot of fans who now want him not to be forgotten, but I personally don’t remember him in the context of this forum considering he hasn’t been active for the past 5 years.
