Floyd Mayweather had previously endorsed the ICO, probably a paid job.
Naah. how dare you think about that? He is a well known crypto enthusiast and probably coulanteered for that job without any payment.
By the way not so long ago Steven Seagal endorsed Bitcoiin project (even the name of the project is retardly phishy) and then left it together with the whole team after the ICO. Why people expect celebrities to guarantee that the project is legit?
