Blockchain, 2Chainz, Tennis chain. What do all these things have in common other than the word chain? Well, 2Chainz probably owns something related to the other two, so thats neat I guess. The man is very rich, and I feel like a lot of rich people own cryptocurrency. We also know by reading his name that he is a man of many chains, leading me to believe that he's got to have at least a few tennis chains, right?
