50 Cent is just an image, record labels set him up with nice cards, suits and events that demonstrate wealth, but in reality he is in severe debt. This is a lot more common that people actually think, I have heard about celebrities faking it until they make it for a long time, but it actually turns out to be true, particularly for rappers.
This is also what I read, although he is one of those few early adopters in the music industry, there are certain reports that he is on the brink on bankruptcy so we really know what's the truth behind the story.
About a few weeks ago, eminem includes "bitcoin" on his lyrics and everyone was elated to see that bitcoin is somewhat going mainstream but I doubt it will bring crypto closer to the masses. If 50 made a lot of money thru his early investment on bitcoin, then good for him, but I wouldn't be surprised if his on the brink of financial disaster as we all know that those kind of celebrities do spend a lot of their money on something that has no value but just to show image that they have tons of money, how ironic.
