I just bought 5 S7's on Hashnest
Their current advertised Maintenance/Payout rate is 35.7% (been between 37-39% for the past 24h)...
After about 18 hours of mining...
Payout Total(BTC)
0.03125827
Maintenance(BTC)
0.02401903
Which yields a true Maintenance/Payout of 76.8%
Is this normal to have some variability in the Maintenance/Payout, or is this site gambling with their credibility? I find it VERY hard to believe that ~80% of your payout is gone to maintenance when the bitcoin price is $600+
It seems hashnest is the only cloudmining company worth putting money into, so if this site is bogus, then that's it for cloud mining.
You are not taken in affect the luck they got. The payout is depending on an average luck. The moment the pool is less lucky then average you cost will be higher etc.
More important why did you decide to buy cloud mining. It isn't profitable.
I bought hashnest because they do real mining, and also they have a market system so that you can sell your hashing power if you're dissatisfied with earnings. So far I'm pretty impressed, the earnings are about what is predicted from mining calculators.
I'm willing to take a loss, just for the experience of trying cloud mining and proving to myself that it's bogus if things go bad
I don't buy the argument that no cloud mining can be profitable. To know that absolutely, you would need to know exactly what will happen to difficulty and bitcoin price in the future. So worth a shot for me
