No. Ads are displayed after check-in and on various other app pages. You are not obligated to view or click on any of the ads to receive rewards. We are simply displaying ads to earn advertising revenue to fund our project until we release PayTrip™ version 2.0 and the Airdrop™ game. In fact, there will be no ads at all displayed in PayTrip™ version 2.0. But, in version 1.0, if you see an ad you are interested in, you are welcome to click it. If not, don’t. It’s totally up to you and won’t impact what you earn.
