50k for every fight you win

You’re teleported into a UFC sized cage with a button in front of you and a referee. When you press the button a random, able bodied man(or a woman if you are a biological female) from across the world between the ages of 16-60 is teleported into the cage to fight you, if you win you are given $50,000. You know nothing about this person, it could be some discord mod who couldn’t throw a punch if his life depended on it or it could be some 240 pound MMA fighter from Siberia. There will be no rounds or time limit, the fight goes until someone taps, gets knocked out, or ref stoppage. You will have 4 ounce MMA gloves and a mouthguard, the rules will be pretty similar to UFC rules(pretty much anything goes except things like eye poking and biting). If you win your first fight you can take a 15 minute break and then fight again for another 50k but if you lose all your money goes. This event is a one time opportunity not something you can consistently come back to. Once you press the button you have to fight no matter who it is, you can’t tap out the second the fight starts, you can’t bribe your opponent, and your opponent will try their hardest no matter what. Would you press the button? If you won would you keep going?
