I never really heard of a “token cap” the only thing I know is just a daily xp cap

There is some sort of gift cap, I'm pretty sure. You can get about 10 from activities (^Paintball, ^Paddleball, ^Soccer, etc), 1 from just playing for the day, and 1 more for completing the daily challenges. Reaching your max gifts doesn't stop you from getting items from quests (^GoldenTrophy) or ^Stuntrunner, though neither of those can award tokens (last time I checked, may have changed since. Somebody can correct me on that.) You can still buy items, recieve gifts from other players, and from the friend-o-tron. I've heard that the boxes you can get from activities resets at a certain time though I cannot remember it and I'm not sure how true it was. If I got anything wrong, please correct me! I'd love to be more in the know about this stuff than I already am.
