Changed my 5 star...Cos earnings Are slow. Why do we have to activate mining Every 3 hours. We bought this app. It should be at least 6 hours. And Satoshi earnings rate is too slow. I have bought many boost plans. It does not earn money back for you , Even If you click Every 3 hours. Almost 30 percent loss for Every bought cloud boost. Better to buy btc from coinbase directly.
