I am using champcash as my cousin brother advised me to earn from there but when I used it I found that it take a lots of time to earn than mouthshut. I stopped using champcash after 2 weeks as it was just wastage to time and battery life of the phone. I earned just one dollar in 2 weeks. And I was too angry that I stopped using it and started using mouthshut application. After few days my brotger also had the same reason for using the application and started using mouthshut. He now earned 920 Rs in 3 weeks.
