I was working on this app from about a year.
But I was just wasting my time and money both.
The system is so bad that they will give you only 1-2 ₹ on survey and other poor facilities they provide.
You will get 10-20 rs on each referrals and they will add you in their Whatsapp group where all the poor stuff is posted every minute. And they will misguide you all the way and they start showing fake bank transfer, money withdrawal etc.
I will earn more on a daily wage than champcash
