There aren't great tips for this one, but two pieces of advice I can offer are to choose the nerd repellent gadget, since that removes 1 of the 3 things you have to avoid entirely, and hang out in the middle of the screen. Coins and tokens aren't too hard to avoid, except for when there is a line of coins that starts around 3/4 of the way up the screen and steadily descends all the way to the ground. It's an unbroken chain, so your only chance to avoid these coins is to start in the middle so that you have enough time to go up and over it. Using the gravity belt can help you get out of the way of coins coming at you as well.
