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 just wish someone would provide math with it. I dont see many cloud mining getting roi.
Some companies like GAW sell upgradable contracts, so you can't really calculate ROI when you buy them. They also have a marketplace, where you can sell the shares after taking early profits.
Here's a couple of posts by people who profited from cloud mining
