but i am not confused because when i checked the mining calculaters then the true faces are shown to me..
at First the shock i got is from the bit-x site..
when i opened the calculator..so it was showing 100ghash as default..i changed it with 35ghash and so i hit the calculate buttion but then i found that i will earn..about 13000-15000satoshi every day but then i thought about the mantainence fees and got that it was higher than my daily earning....so that clearly means it only accept the higher investments
so then i visited scrypt.cc (its a less scured and less trustul with deposits as because it is usually getting hacked..)
i deposited 0.052btc and bought some khash...i got about 13020khash .so i went to calculator..and typed and increased the khash amount until i reached 1btc then i saw that its paying 0.007btc if i buy 1btc worth of khash...that means 0.7% everyday
now after all lot of things like this i am thinking why we invest in cloudmining when we can trade and can make more than 1% daily and that is much safer from these things at least we will have control on owr coins
Of the three sites you listed only Bit-X has an exchange you can sell your hash on. cex.io is not selling hosted mining at present, and they were not a good deal when they did. scrypt.cc is a scam, a ponzi scheme you should stay away from.
If you are serious about trading or holding hosted bitcoin mining you will eventually wind up at Hashnest. Hashnest has different mining contracts you can choose from with different risk/reward. Prices and maintenance fees are better than Bit-X. Antminer S5 is the safest hash to buy and price is depressed right now, so if you believe bitcoin price will increase in next few months you can earn daily income from mining and as a bonus, sell your S5 hash for a profit when price increases.
Trading is also fun and can be very profitable at Hashnest. But since price of all contracts is in a down trend, and you can not sell short at Hashnest day trading is not profitable at present. Once bitcoin price leaves the trading range and starts uptrend again making 15% per month trading at Hashnest is not hard at all.
