Long story short: 2 years ago a women sued him for releasing a sex tape and won 5 million bucks. 50 smartly declared bankruptcy, claiming being suddenly poor and illiquid. A year earlier he was paid 700 BTCs for an album when BTC was in the $660 range. During the bankruptcy proceedings that crypto was somehow forgotten, although its value was about half a million. Now it is still unused and worth, well you do the math and don't forget to add BCH's value too. 50 suddenly remembered where his wallet was and would like to thank the court for the oversight. The point of the story is that apparently cryptos are still good for avoiding financial responsibilities. https://www.coindesk.com/rapper-50-cent-now-bitcoin-millionaire/
And their alternative is still used by governments to steal from working/producing people in a massive scale, manipulate the economy based on political agendas and criminals too, with far larger negative consequences. Besides,the article said that he avoided his obligations by declaring bankruptcy in the first place, so, another government/law flaw.
