How to monetize the WinPhone 8.1 app?

Question

Monetization

I wrote an application for windows phone 8.1, downloaded 250-300 people a day, but decided to monetize it, made it paid and the downloads dropped to 0, I realized that it would not be possible to monetize it in this way, and decided to monetize it using advertising, but I ran into a problem, that I did not find any advertising platform that would support windows phone 8.1 and the Russian market.
Maybe there is some platform that works with 8.1?

Answer 1

First, make in-app purchases. For example, if you have a messenger, then texts of no more than 100 characters are sent as standard, and for 10 rubles - as much as you want, etc. ...
and secondly, there are a lot of ads with a winphone, the standard Microsoft one works fine in the CIS.
