Judging from their partnerships with a mainstream sports personality and the UFC, I guess yeah. Sportsbet is right up there too tho. Their banner and logo could be seen all around the weekly EPL matches which is a huge thing. At least for me being both a fan of the EPL and BTC... I’m guessing F1 will be the next thing to go to.
Sportsbet.io deserve what they are now, they are a good website and their services are good, the only way for Sportsbet.io is to go up even further and become more prominent in other sporting events, I hope that someday they will do a partnership with NBA, PBA, and the International (DOTA2' biggest tournament).
