This is worst app. Please don't buy any booster packeges to increase hash speed, because if you buy 10X also it will work only basic speed. It's true. I bye two 5x package with nearly Rs.4000 to increase maining speed. But Daily Iam getting only 0.00001200 satoshes. If cunvort this satoshes in to indian rupees that's only Rs.35 only. It means my monthly income will be 35×30=1050 rupees only I will earn. I spent 4000rupees for 10x speed to earn 1050rupees only. Please don't download useless app.
