Hi, I implemented it in my app and It's not worth it. Earnings calculator on their site is fake. I had most of my users from Tier 1 (USA) and I didn't even earned half of calculator's result. After about month or two of using this SDK my app has been suspended and removed from Google Play due to malicious behaviour. I wrote to GP support, but of course there is no way to achieve anything. I'm not 100% sure that suspension happened because of GlobalHop SDK, because GP support "couldn't provide more information" (yeah... sure), but I don't have anything else in my app that could break that rule. So if you already implemented GlobalHop SDK I recommend you to remove it and update your app ASAP.
