50 cent, the rapper responsible for bringing you such indelible party hits as “Candy Shop” and “In Da Club,” apparently agreed to get paid for his 2014 album Animal Ambition in Bitcoins, according to a post from TMZ. The rapper sort of confirmed this, by posting a screenshot of the article on his Instagram account with the caption “Not Bad for a kid from South Side, I’m so proud of me” and the shrug emoji, plus the money bag emoji. Later, in the comments, he added: “I’m a keep it real I forgot I did that shit,” with the face-palm emoji, plus “Lol.”

All you have to know about bitcoins is that they are a cryptocurrency—so, it’s a digital currency, you can’t touch it like a dollar bill or a nickel—and that while literally no one cared a few years ago, there has been a recent uptick in interest around them (as well as other cryptocurrencies) and as a result, they are now worth more.

And because they are worth more, 50 has literally made gobbles of money just because he agreed to get paid in this random internet money thing in 2014. According to TMZ, Animal Ambition made about 700 bitcoins, and one bitcoin was valued at $662 U.S. dollars at the time. At the time of writing, one bitcoin is worth about $11,300. So 50 could have—$11,300 multiplied by 700—about $7.9 million right now, all from one album.

But—and you know this if you know any #bitcoin #bros on Twitter or IRL—THE VALUE OF BITCOIN IS FLUCTUATING ALL THE TIME. It peaked around mid-December and has been pretty consistently falling and rising since then. So if 50 wants to hold on to his millions, he should cash out now, in my opinion. I’m a pretty risk-averse person, and I don’t believe in what I can’t see anyway, and by its nature, I can’t see bitcoin. They are real, I get that, but I don’t trust them. What I’m saying is: 50, please talk to your financial advisor.
