I am going to build an Ethereum mining rig for 150 MHs with initial investment of around $2000. More than half of investment will be invest from my earnings, the rest I ask for the loan. The project will bring me back approx. $300 or 0.5 BTC per month. Beside that I have my salary to repay it in case of any unpredicted event and there is no risk for loan givers.
