Initially it was good when I downloaded it an year ago. I have withdrawn more than 10 times and I got my investment back. But now it is totally different. If you mine for 3 hrs you get just 0.00000005 Satoshi that means to have minimum withdrawal you need to mine 200 times 200*3=600 hrs for 25rs. Even booster plans are not worth buying. If you are planning to buy the app now don't buy.
