You should give xhamster premium plans according to country currencies & not just dollars, I work in a service sector company and I feel it is duty of service provider to deal with currencies not clients.

more over in developing countries you should match your plans according to the online media service providers like netflix and amazon prime,

I don't know what your marketing team does but you should use facebook and instagram for connecting to people (mainly through memes nowadays like political parties use it for their agenda and propaganda just like china).

think about it if you charge 7 dollar for month just 10 out of 1000 customer will pay, But if it's fair price more than 100 will pay and profits would at the end of the day maximize only.

Thatz just an advice from a long time customer :)
