being someone who lost some bitcoins invested at amhash.com, hashie.co, hashprofit.com - EVEN flowertechnology.com and cloud.zenminer.com (appeared to be SO LEGIT
) - a pattern emerges "if something is too good to be true, it's likely NOT TRUE!" it may be VERY WISE to STAY AWAY!! just saying...
i too would like to know how surehash arrives at their payout thresholds, and exactly what type of mining equipment they have conjured up. if ONLY FOR A LAUGH...LOL
i had faith and ignored all the warnings signs that many offers mentioned above were NOT LEGIT, oh well "Lesson Learned - Never Again"
and now surehash claim to have 203 customers and sold 7,600 ghs - <sigh> i wish those folks much luck, they're gonna NEED IT!
Bitmaintech has a cloud site called hashnest.com that looks interesting. At least we know they are legitimate miner manufacturers! has anyone signed up for cloud mining hash there? please share your experience, if so. thanks and Happy Mining Folks, but be careful who you give your bitcoins to. don't get burned like i have, it's really not so much fun when that happens and it ruins your ROI schedule...
***update - i just took a look at hashnest.com myself, and the following was a message (within quotes) posted there:
"admin on 2015-04-14 06:18:25
Due to the falling bitcoin price this week, ANTS2 and UMISOO contracts currently have higher maintenance fees than they do revenues.
From April 14th, 2015 (Beijing time, GMT+8), Hashnest will calculate once daily ANTS2 and UMISOO expected revenues on a PPS basis. This calculation will be performed between 12:00 and 13:00 Beijing time each day. If this calculation returns a negative result, the losses will not be deducted from your remaining balance.
If negative income conditions persist for ten days in a row, ANTS2 and UMISOO contracts will be terminated.
* Currently, theoretical PPS return per terahash should be 0.01017BTC, and the daily electricity cost per terahash of ANTS2 and UMISOO is $2.304 USD. As long as BTC price is lower than $226.54 (2.304/0.01017), the electricity fee will exceed the mining rewards.
* The bitcoin price used will be the CoinDesk BPI USD price."
***and so the lesson here is, if a legitimate miner hardware maker has problems being profitable with cloud mining...well you can fill in the rest...
