In November, Bjork said she would accept four different types of cryptocurrency in payment for her new album \"Utopia\". In December, 45 musicians agreed to accept Monero for sales over the holidays, and moves are being made to put music on the blockchain.

Ahead of them all, perhaps, is the Rap artist Curtis \"50 Cent\" Jaackson who back in 2014, agreed to accept payment in bitcoin for his album \"Animal Ambition,\" and is now sitting on multi-million dollar revenues. A celebrity gossip site reported on January 23rd that the decision had brought in around 700BTC, through payment processor BitPay. At the time of the original sales, that amount would have been worth around $400k, but with recent stock rises, the TMZ article estimates his current holdings to be worth somewhere in the region of $7m-$9m.

50 Cent confirmed the celebrity article\'s information, posting the text on Instagram and commenting that it was \"Not Bad for a kid from South Side.\" He also claimed that since the decision to accept BTC for the album, he had forgotten he had it.

The rapper is well known for his entrepreneurial successes, with an extensive investment portfolio that includes (among other things) dietary supplements, a clothing line and real estate.
