Amidst the current crackdown on initial coin offerings (ICOs) in China and around the globe, some cryptocurrency fans are holding strong.

International boxing star Floyd Mayweather, for one, posted yet another image on social media citing his allegiance to an ICO yesterday.

No industry novice, this is the third social media post Mayweather has made promoting an ICO over the last month. The ICO in question this time is called Centra, a crypto credit card startup which is holding a coin offering later this month.

An earlier tweet suggests he is working with a digital marketing company called the Crypto Media Group, which as reported by Vice, is seeking to court celebrity endorsements for cryptocurrencies.

Spurred by similar interest in the industry, Paris Hilton also promoted an ICO on Twitter earlier this month, however the celebrity heiress was careful to emphasize that it was “#NotAnAd,” in reference to her supposed industry expertise.
