Champcash is an absolutely fake site.i was referred by one of my friends.she said me to install the app using her referral code and then to refer friends using my referral code, and I can earn lots of money.but neither my friend got any money for refering me and neither did I get anything for referring nearly 30 of my friends.i just wasted my time on this useless app.they are simply cheating people.please be aware.
