Boxing champion Floyd Mayweather Jr, made waves last month when he promoted an initial coin offering on Instagram – and he's just endorsed the second one on Twitter. The promotion of the ICO for the Hubii Network, which is developing a blockchain-based content marketplace, comes days before he is set to fight Conor McGregor.
In the message, he dubbed himself "Floyd Crypto Mayweather", and even hinted at an ongoing promotion effort with the hash tag "#CryptoMediaGroup". In late July, Mayweather promoted the ICO for the Stox project in a post on Instagram. Stox went on to raise more than $30 million in its token sale.
