Not really a synergy between crypto and sports imo. More of how companies could leverage this exposure of sports into crypto and create bonuses and promotions with it. And if you meant just getting some small bonuses, highly doubt it's worth the effort and time for both businesses and users to actually use such a thing. Such bonuses would probably apply a LOT more with casinos than exchanges. Heck writing this I realized this is the gambling discussion section, why are you discussing about exchanges and sponsorships?

If we were talking about the real synergy between crypto and sports, I'd more liken it to how some sports teams have made their very own crypto tokens. Idrk what happened with it afterwards, but hey, it's something.
