Which pay-per-impression ad network should I use in my app (Russian audience)?

Question

Android

There is an Android app aimed at high school students (well, first-year students), it makes no sense to make it paid (for obvious reasons), so the only way to get back $ 25 for registration is advertising.
Because schoolchildren are unlikely to often click on ads, it was decided to take an advertising network that would also pay for impressions.
Actually, what ad network fits this description?
There is TapContext, but they pay somehow not enough + the minimum price for withdrawal is high + the banner is shown the same (some kind of antivirus, although maybe I'm just unlucky)
