Thank you Christoph for that interesting idea and for writing this idea up, especially also for the spreadsheet which can come in handy. But did you think about Arbitrage? I think that’s a potential problem here. When everyone starts to provide their apps with different prices on different countries, people will start creating fake accounts in the countries with lowest GDP and buy apps that way. I know, that’s inconvenient but I’d suggest not to make the price difference too great to prevent misusage like this. Just saying. 😉
