It sounds interesting. But in my own opinion, you can't earn a decent amount of btc just using an app in phone.Almost 2 years ago I have tried many bitcoin app in hoping that I can get extra income out of it. But the result is not what I expected. All the apps I installed needs the minimum amount of btc to be abl to payout. But unfortunately I calculated my earnings a day and found out that I can reach that amount in a year and a half at 8 hours a day. So I stop doing that because it took too much of my time. So let me try your app. Maybe its a promising app since I didn't find any one.
