Somehow they missed out his name. He should have been on the top of the list. Richard Branson was/is one of the biggest supporters of Bitcoin, but I am not sure whether he still supports it.
I wouldn't say he's one of the biggest supporters. Apart from accepting them for Virgin Galactic he seems to be pretty quiet on the subject.
No one puts their money in to an investment without getting the details on how the money will be spent. So he must have heard about Bitcoins, its potential risks and the exchange rates.
Gweedo is probably right. Rappers like Nas usually just look to put their money into something on the back of advice from whoever it is helping them to get a bit richer. He may know some of the details about the company but I'd be sceptical. It's probably more a matter of his business or investment partner/manager just saying hey, this company looks like it could be one of the next big things, want to invest? I'd be pleasantly surprsie if Nas was into or aware of Bitcoin or invested in off his own intuition though.
