Various cloud mining site have various rates of earnings. And your earnings will depends from the price you will buy 1 ghs. My advice is to not invest in cloud mining. You will not earn on those. If the cloud mining site will be not a scam site the prices that they will give you to buy ghs will be very high and you will never earn something decent from those. Or you will earn something like 2-3 dollars after 8-12 months.

I have experience on this because I had mine in cloud mining sites myself.
