IS there any ROi with cloud possible ?
Try cloud GH's that charge no more than a 30% maintenance fee (equivalent to 0.12 kWh) and hold on for 365 days and you will ROI. If you want a quick ROI then buy your own hardware.
Can you show some math behind this? I cant think of any cloud services that ROI in 3 months is normal.
Right now, many people claim that LTCGear ROI in 2 months. But I won't want to risk my money..
I haven't invested so I can't show you the math, but I've seen posts or even whole threads of people who claimed to have reached ROI in the last 3 months.
If I'm not mistaken most of these people used sites where it was possible to trade contracts.
