I'd vicariously love for you to be able to make some/more revenue with this!
+1 on @redox99's comment that charging in rubles is most probably confusing, and that a flat $10 usd/month would be easier. I also would think that renewal should actually be on by default, not off - if people want the service and/or to support you, having auto renewal off is more of a hassle for them (the customers who want to pay you!) as they'd have to have to... re-enable their service? every 30-90 days?
and another point I wanted to bring up is that it feels to me like a small text-based advertisement from ethicalads.io (the folks behind the ads on Read the Docs sites) or carbonads.net (btw I have no affiliation to either) could definitely... bring in some not-bad revenue pretty much immediately?
again, huge congrats on your project and I truly wish you'll be able to find some path to monetization. cheers!
As a Brit, I'd rather GBP...
Isn't this comment a form of US defaultism?

Even if you don't know the conversion, something in the range of 50-200% is a lot easier to adjust to, whereas Rubles are on a very different scale (1 GBP = 108 Rubles)
Obviously the ideal would be local listings, but USD is probably the most-familiar reference point if you have to choose exactly one
Just show and charge 10 USD. You can localize that other currency (Rubles?) if GeoIP matches.
The point is that you need a bank to accept a payment in foreign currency and debit it into your account.
