High Tech Park in Kyrgyzstan will probably require the most income coming from software purchases, not ads revenue. You can check with the local lawyers. Mine did not suggest HTP in a similar case. Without park KG taxes will be 4% CIT + 10% on dividends to a foreign person. Unless you can benefit from it by subtracting those 10% from the dividends tax in your home country like I do or manage to get into High Tech Park, you can get a better rate on Cyprus (12% CIT + 0% on divs).
With an average salary in Bishkek being around 350 USD, maintaining a︀ presence or outsourcing some tasks you'd rather not do yourself will be cheap enough.
