During my research on available Cloud Mining services I have read plenty of warnings to be aware of scams. E.g. companies that aren’t actually mining, but that are paying you your daily profits (sometimes with the investments others make). Suddenly they are gone with (most of) your investment, and since bitcoin is anonymous you can’t track them.

For me there turned out to be two companies that are recommended and trustworthy and many others with warnings and negative experiences. Bit-X and Hashnest had some good recommendations, so I took a closer look and compared them.

Maybe the maintenance fee is most important, because this affects our daily profits. First Bit-X: it has a maintenance fee of 0.00000700 BTC for 1 GHS/Day. At the moment (June 2015) this is about 69% of your daily earnings. I am not sure if the fee is changed when the BTC price rises. If not, this would mean that also your maintenance fee rises. Next is Hashnest: it has a maintenance fee of $ 0.001175 for 1 GHS/Day (Antminer S5). This is 0.00000470 BTC with today’s exchange rate of ± $250,00. At the moment this should be 46% of our daily earnings.

The price of 1 GHS is also important. Combined with the maintenance fee determines this if I eventually will break-even or not. On Bit-X a GHS costs 0.00164009 BTC and on Hashnest a GHS costs 0.00144999 BTC. So far Hashnest seems to be the best choice. It offers more GHS per BTC invested than Bit-X, with a lower maintenance fee. Besides that you can even choose between different miners. However the Antminer S5 is currently the best choice, I think. It is the most power efficient one you can choose on their website. So It would run much longer instead of the other ones before it doesn’t cover it maintenance fees anymore and is shut down.
