Please don't invest in mining without first learning how to compute your expected return. Too many newbies blindly invest and end up losing money.

For example, on cex.io, a popular cloud mining site, 1 GH/s costs 0.074 BTC, but 1 GH/s will never mine more than 0.05 BTC. For every GH/s you buy on that site at that price, you will lose up to 0.024 BTC.
