Easy Money (Tested)
Note: You need two controllers, two profiles, and both of the profiles must have some amount of each koin.
Enter the versus screen and load up two profiles. Pull the R trigger and bring up the wager screen on both controllers. Select one koin type and hold up until it won't go any higher and select ok with both controllers. When the versus screen comes back up unload one profile and reload it and do the same to the other. Pull the R trigger and bring up the wager screen again on both controllers and you should have won the money wagered. Do this continuosly with the same koin (very important) until you are satisfied. After you are done pull the R trigger and bring up the wager screen again on both controllers and wager 1 koin and hit ok on both controllers and finally complete a battle and when you are done and have won the 1 koin exit out of the versus screen and go and take a look at your player profile and you now should have all the koins. Repeat this for every koin until satisfied.
