Hi everyone, I bought 4 TH which cost me 40 dollars for one month. After this one month, I thought that I will get some benefit or at least I will get only my money. But the reality is that I lost 10 dollars from the amount of money that I invested. The conclusion is this if you want to invest in this site be sure you will lose part of your money or you will not get any benefit because this site gets high electricity and maintenance fee. they sell you hashpower and they take part from the BTC that you mine.
