Pro tip
start saving your daily challenges for the next event. They will give you a big head start.

For many players, once you've been playing for enough years, challenge donuts and in game cash are not as valuable as having a head start in an event - and avoiding the grind to finish. I will also save the challenges once I've completed each act as well. It's a jump start on the next prize track and/or the bonus donuts for completing the act.
