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.
how do you calculate never mining more than .05 BTC? so investing in CEX results in losing up to .024 BTC? so invest, or no? it looks profitable atm!
