For 50 bucks total (can be split vs different trusted people in BCT), I say it won't happen. No way will there be a boxing match between Mayweather and Khabib. 50/50 odds and payment on June 1, 2019 to the winner.
Ok let's agree on the terms. I'm betting that there's no bout between Mayweather and Khabib in boxing. If a there's a boxing match between them before June 1, 2019, you win. If there's none before June 1, 2019, I win... But if there's a bout, but in MMA or some other form of fighting, it's a draw.
50/50 odds, payment on June 1, 2019. 50 bucks. Go?
