There is also Triple Winnings for main event Dustin Poirier vs Conor McGregor, and I am going to give it a go betting on this one.
You can also watch live stream for free on Stake website.
There is a rule on promo like "the first bet per match", so betting on one event makes the account ineligible for the second promo.
Regarding the Wimbledon tournament, I think it is a trap like NBA promo. Even 1.03 odds can be a fake if the player decides not to push score far, I have seen so many high-rollers bet on low odds for wager which is extremely dangerous, IMO.
