Floyd Mayweather Jr
Sometime in 2017, the world’s greatest welterweight boxer posted a picture of him brandishing a card with the caption saying he was spending Bitcoin, Ethereum, and other types of cryptocurrencies in Beverly Hills on his Facebook and Twitter pages.
In retrospect, the widely accepted belief is that the post was a means of announcing he had invested in different cryptocurrencies.
Shortly after, Mayweather’s involvement with Crypto became more pronounced as he promoted the ICO of Stox $STX on his Instagram page, touting his investment in the coin.
