Boxer Floyd Mayweather showed his interest in cryptocurrency via Instagram on two occasions.
In July, he posted a photo of himself on a private plane next to a table covered in money with the caption:
"I'm gonna make a s--- t-- of money on August 2nd on the Stox.com ICO." Stox, a sister site to Invest.com,
 is a bitcoin prediction market product.

In August, Mayweather took to Instagram again to show his support for
 blockchain-based decentralized marketplace Hubii Network's ICO. Under a photo of himself,
the boxer added the caption, "You can call me Floyd Crypto Mayweather from now on."
