Actually I am using this app from 6 months. very very nice app. Actually found this app from my friend. Actually he told me about mazuma expertise. I am earning in that app. So he said you need pay wallet for withdraw. So he said to install this app. I installed it. Very good wallet. I didn’t get any problem till now. I downloaded all the bitcoin satoshi earning apps and using them. Then sending that satoshi to zebpay. So it is working very well. Zebpay is one of the best bitcoin wallet.
