A year ago I started to use this app and it was a wonderfull in everyway. They always had rewared a good amount of satoshi but things getting worse when they reduce the reward 50 to 10 satoshi. The process of claiming reward became very slow and sometime it takes over 20 days to claim reward to my bitcoin wallet. The only surest way to earn bitcoin is mine it through you pc. There is one time this app was helpful to earn satoshi but now this app is became scam and waste of effort
