Topic: Cloud Mining Rating System - page 3. (Read 5639 times)

Screenshot is fine I think. It's not the kind of data you need much interaction with.

A screenshot of some sort of a barchart as alienesb suggested would be nice too


They are cheap (although ROI number will get worse after the recent diff adjustment - I'll recalculate after tomorrow's payout) and about as transparent as a cloud service can be. No surprise there. It's a shame that the market is so depressed that even amhash probably wont ROI unless diff stays below 5%.

A few notes on others:

Demonstrated mining activity consistent with claimed ghs or mhs (0-20 points).

I would give hashie a point or two here. They had their rigs pointed at BTCGuild on a couple of occasions and I event took a screenshot. That doesn't prove much since they could just be using rentals temporarily but at least it's more than nothing. http://i.snag.gy/1ysVt.jpg

Genesis Mining AFAIK has been confirmed to have ordered hardware from Zeus and Spondoolies. Don't have a link, sorry.

Relies on MLM and affiliate techniques for sales (-20 to 0).

Doesn't CEX have an affiliate program? I don't know how active it is now but a few months back there was some spam here in the forums.

Legal compliance/T&Cs (0-20).  Has contractual commitment with clear and well drafted mining agreement, with no overreaching terms, penalties, etc. (e.g., Genesis Mining).

Wouldn't it be fair to give GAW 3-5 points for the T&C? It sucks in many ways but at least gives a warning to someone who can read the fine print. The only thing I'm not sure about is whether you have a reasonable access to ZenCloud TOS (which is separate from GAWMiners) before you sign up for the service. I know it's on the log in page, but not sure how new customers get to see it.

Hashie has terms page, maybe worth a point or two? https://hashie.co/terms

Relative ROI (relative static ROI)

Hashie should get 6 points. Currently about 175 days, perhaps slightly more after the adjustment but still within 200 days I think.

Peer review and response to criticism (0-20).

LTC Gear maybe deserves more than 0 here - there are active threads on litecointalk, Chris responds to e-mails.

Done in part.  Let me know what you think about the picture/table.  You are right about how much work this will take, which is I am asking folks to help out with scorecards please!

I will probably need to post a link the the spreadsheet in the future, and reserve the table/image for a ranking summary since there won't be room for the whole thing after I add another service.

Done, but I used a spreadsheet and print screen for now.  I hate tables here, drives me up a wall to edit.  Other ideas?  I thought about a spreadsheet on Google Docs as someone suggested, but that requires clicking a link ...



Added Amhash.  It is #1 in the rankings by a longshot.  Interesting!

Why not whip up some bar charts

I have one request. If possible op It would be better if you did it in table style, not 'wall of text' style in my opinion. Other that that. Great job.

Is it possible to compress it a bit? Put it in google doc or make a table, it's hard to compare the numbers the way it is.
This could require a lot of work if people actually start leaving feedback, good luck!

His thread, his rule, and it's a sensible one. You don't have to post the score of you don't want to.

eightcylinders, you might want to try tables for formating. They suck here but still better than plain text I think.

Also some bold/color/larger headers and subtitles might help with that wall of text in the OP ;-)

Great effort, I hope you'll keep it up.

1. I dont get the reason why U'll add scorecard of PB Mining, Hashie, LTC Gear, Genesis all by yourself and I have to take the responsibility of adding scores for cloudmining.website, where I'm not allowed to keep my referral !!!

2. As a newbie my signature does not allow referral.

Sorry, this is a community project for the good of the community - NOT a way for folks to push their favorite affiliate marketing campaign!!  I removed my own referral link in my sig so that there is no possibility of a claim of bias.  If I allow referral links, this whole project will become a spam fest where everyone with referral links will post (info about their favorite cloud mining service, but that will be biased because there is too much incentive to pump up the service in order to get referrals.  Keeping it referral link free is the only way to achieve at least some objectivity.

EDIT: Bitcointalk rules currently allow for some referral links in sigs.  While I removed mine, I cannot force anyone to remove theirs and mods won't pull posts based on referral links in a sig... so if you MUST use a referral link, put it in the signature NOT in the post.

If u keep my referral link in your list, I can take the pain. Not otherwise.

If you can fill out a scorecard for them, I will add them to the second post.

Well... I was not aware of the ref thing. Sorry for that.

Ya it would be Genesis-Mining. I made the typo.

Even if we dont have enough proof about the sell side activity, I think we should include them in the list to be complete. PB Mining, Hashie etc. dont have any sell side activity at all, but they are included !!!

I looked at the link and discussion but it seems like they are at least pretending to want to BUY capacity.  But that could be a spoof to get folks to click on their website.  There is (as yet) zero discussion about their sell-side activity so I cannot include them yet.  Seems very sketchy but if there are folks who have real data and can fill out the above scoring, I will add it.  But please don't post referral links here it is spam and will be reported to mods in future.


You meant Genesis-Mining rather than GAW I think.  I read the reddit but the issue there is the use of affiliate marketing and dummy accounts to promote.  That would give Genesis a negative score on use of MLM/Affiliate mining.  I will consider revising scoring to add this factor for Genesis.

Keep in mind, my idea for SCORING is that ALL relevant factors are considered, not just one.  The fact that Genesis is kicked off the subreddit is relevant to marketing techniques, but not the other factors.

Excellent.

Scott-

EDIT November 5 2014: Added quick reference spreadsheet screenshot, added Amhash, reformatted scorecard - please use new format!!

EDIT: My to do for this second post: (1) reformat to list scorecard by company rather than by scoring factor, (2) put into grids by company, (3) add on scorecards for companies suggested by others.  Please help me out if you want a company listed by proposing scores for that company!!!  It takes a lot of work to put together scores and I cannot keep such a list on ALL mining companies up to date by myself... but again, NO REFERRAL LINKS in the post - I want objective and community oriented responses rather than sales pitches]



Note that I can only review cloud mining services that I personally have used and/or that I can find info about easily. I am NOT limited to the companies listed, but folks need to help me out to add new companies by filling out a scorecard and putting in explanations for scores where needed!!!

Note also that a company may offer different products which would be scored differently, so pay attention to the "Product/Algo"!

Here are my initial scoring (TDB: convert into scorecard format with explanations by company)

Demonstrated mining activity consistent with claimed ghs or mhs (0-20 points).

GAW: 5 (proven orders for 5 Petahash sha256 from Bitmaintech, but no info on scrypt hashing capacity; T&C's and statements by CEO indicate that hashlets may be virtual and not reflect actual mining activity)
Umisoo (Hashnest): 10 (claimed 4 Petahash farm of S2 miners with real time tracking of farm; some miner failures have resulted in public disclosure of mining capacity reduction indicating that farm stats are likely real; ability to track hash rates of individual miners but with no proof of actual mining)
Bitmaintech+Umisoo (Umisoo.com): 20 (miners must be purchased, and are hosted by Umisoo, with ability to direct to pool of users choice)
KNC Cloud: 10 (pictures and reporters have visited farm; admission of mining using customer equipment makes KNC untrustworthy for purchases but bolsters cloud mining capacity claims; real time monitoring)
Zeushash: 5 (early pictures and public mining operations were disclosed, but almost no public information since forming of Zeushash; provides daily payout info only)
Zoomhash: 0
LTCGear: 5 (early evidence of FPGA farm well established, but ASIC operations are shrouded in mystery)
Genisis: 0?
cex.io: 20
Hashie: 0
PB Mining: 0

Backed by known and trusted manufacturer or disclosed, established financial partner  (0-20 points).  

GAW: 10 (seems to have good relations with Bitmaintech, and GAW itself is/was a real company before moving to cloud)
Umisoo (Hashnest): 15 (Hashnest is part of Bitmaintech, relationship with Umisoo unclear)
Bitmaintech+Umisoo (Umisoo.com): 15 (relationship with Bitmaintech unclear, but they appear to be close)
KNC Cloud: 10 (KNC is a major manufacturer, but trust factor on low)
Zeushash: 5 (Zeus is too new to be trusted fully, but they are one of the largest scrypt ASIC manufacturers)
Zoomhash: 0 (unclear, maybe only reselling Zeushash?)
LTCGear: 5 (like GAW, LTCGear was a real company/person with established cred but no recent info)
Genisis: 0?
cex.io: 20
Hashie: 0
PB Mining: 0

Mining hash rate is subject to audit/verification (0-20 points).

GAW (Prime and Zen Hashlet): 0 (payouts seem unrelated to any actual mining model; CEO claims payouts based on other business such as miner rentals, coin IPOs)
Umisoo (Hashnest): 10 (farm stats and individual hash rate within farm disclosed)
Bitmaintech+Umisoo (Umisoo.com): 20 (total control over hashing and pool selection)
KNC Cloud: 10 (pool earning rate and stats disclosed)
Zeushash: 5 (pool earning rate disclosed but no hash rate graph or stats, and earnings rates are below model predictions)
Zoomhash: 0
LTCGear: 5 (earning rates closely match LTC, DRK and VERT coin mining modelling stats, but no disclosure of actual pool mining stats)
Genisis: 0
cex.io: 20
Hashie: 0 (upgrade promised where miner would be able to direct hash to pool of miner's choice, but so far not available)
PB Mining: 0

4.  Resale market or buy back exists and is verified to be working (0-20 points).

GAW: 15 (lots of issues in market, but in general pretty effective way to exit if you don't like; GAW takes 10% commission)
Umisoo (Hashnest): 0 (will open market when round closes, but so far no market)
Bitmaintech+Umisoo (Umisoo.com): 0 (no way to sell, must take delivery of miner)
KNC Cloud: 0
Zeushash: 0
Zoomhash: 0
LTCGear: 10 (ability to transfer shares, and robust private non-LTC sponsored market due to high demand and limited available shares)
Genisis: 0
cex.io: 20
Hashie: 20
PB Mining: 5 (allows and supports private sales but no market and demand is not very high)

Repeated problems exist with withdrawing payouts over period of more than a week (-20 to 0 points, negative adjustment indicates red flag).

GAW: -10 (seems to be improving but issues with withdrawals plagued system for weeks and still pop up)
Umisoo (Hashnest): 0
Bitmaintech+Umisoo (Umisoo.com): 0
KNC Cloud: 0
Zeushash: -10 (withdrawals often require customer service email, but those are usually effective within 24 hours)
Zoomhash: 0
LTCGear: 0 (no applicable since LTCGear does not maintain an online wallet)
Genisis: 0
cex.io: 0
Hashie: -5 (a few reports of problems, but I have never had an issue to date; however, website down a lot so for now they get a negative adjustment until kinks worked out IMHO)
PB Mining: 0 (no wallet, coins seem to come from mixer)

Below market rates per ghs/mhs and/or above market payouts promised (-10 to 0 points, negative adjustment indicates possible ponzi scheme, pyramid or outright fraud).

GAW: -5 (was -10 at start, but now they price hashlets at or above market rates; however, repeated promises of $100 prime prices and hashbase/hashcoin shooting to the moon etc. still troublesome; justification for hashlet pricing seems to be based entirely on promised Hashbase and Hashcoin ICO)
Umisoo (Hashnest): 0
Bitmaintech+Umisoo (Umisoo.com): 0
KNC Cloud: 0
Zeushash: 0
Zoomhash: 0
LTCGear: -10 (while LTCGear/Beekeeper has almost no marketing, resellers and affiliates often make claims of above market payouts and in fact historical payouts are above market; price per mhs is below market)
Genisis: 0
cex.io: 0
Hashie: 0
PB Mining: 0 (historically they were too cheap and had payouts too high, but now they are more in line with market; may have been a loss leader strategy)

Relies on MLM and affiliate techniques for sales (-20 to 0).

GAW: -15 (affiliate program, reseller program; resellers actively engaged in forums and in pumping up values)
Umisoo (Hashnest): 0
Bitmaintech+Umisoo (Umisoo.com): 0
KNC Cloud: 0?
Zeushash: -10 (affiliate program, reseller program)
Zoomhash: 0?
LTCGear: -5 (affiliate program)
Genisis: 0
cex.io: 0
Hashie: -3 (affiliate program but at a very low and unattractive rate)
PB Mining: -10 (affiliate program very lucrative and primary method of marketing)

8.  Legal compliance/T&Cs (0-20).  Has contractual commitment with clear and well drafted mining agreement, with no overreaching terms, penalties, etc. (e.g., Genesis Mining).  

GAW: 0 (T&C's imposed after many customers purchased; new terms are likely unenforceable as users are required to agree in order to access miners; T&C contain clauses making hashlet hash rates unenforceable as unrelated to actual hashing activity)
Umisoo (Hashnest): 10 (detailed T&C)
Bitmaintech+Umisoo (Umisoo.com): 15 (detailed T&C, SLA and ownership of miner)
KNC Cloud: 10 (contract)

EXPLANATION BELOW:

I am developing a scoring system for cloud mining companies.  My intent is to make this a community based system with discussion here about the right scoring methods, and scores for each cloud mining company to be determined and posted here.  Feel free to add, criticize, or propose additional components.  My second post in this thread will be my scoring of the companies that I am familiar with as a customer and that will change over time obviously so I will do my best to keep the grid in the second post up to date.  This first post is purely explanatory.

I am convinced that cloud mining is the future - for better or more likely for worse - of bitcoin, litecoin and any future coin that can be hashed at high rates using ASICs.  The reasons for this are the ability to scale massive farms and reduce investment in both capital (cost of miners) and operations (hosting and electricity) far more than any solo miner can achieve.  Pools were just one early form of collective action, then came hosted group buys, and now cloud mining.   All paths seem to lead inexorably to collective action to keep costs low and achieve economies of scale.

On the flip side, cloud mining in bitcoin and scrypt is a perfect setup for ponzis, pyramid schemes and outright fraud.  Anyone can make a pretty web site and run a simulation showing virtual mining activity while having no miners or fewer miners than the hashrate sold... Given the long ROIs now even for high end miners, payouts can be easily made from new investors (ponzi scheme), and with extensive use of affiliate and reseller programs (pyramid scheme) a good huckster can ensure a long term inflow of capital even while making larger than market payout returns - at least until the scheme collapses and the last round of investors are left with nothing more than a bankruptcy claim!

Mt.Gox also proved that even established cloud services (not even mining in the case) can start out legit and end up as massive frauds when there is no transparency and only a few people in charge.

Unfortunately, with difficulty skyrocketing, and coin prices in the toilet right now, cloud mining is the only viable alternative if you want even a chance at ROI.

So, in sum, cloud mining seems to me to be here to stay, but the fraudsters and hucksters will have their bloody romp through the flocks of sheep before the legit operators actually shake out and/or some kind of monitoring system gets put in place to prevent bad people from taking advantage.

With all that in mind, I have put together a little system that I find useful in "scoring" cloud mining companies.  The scoring features are broadly grouped into 3 categories: Legitimacy and Transparancy (100 points), Remedies (50 points), Relative (Static) ROI (50 points), and Red Flags (-50 points).

So the score can range from -50 to +200 points.

Here is my description of how I score each component:

(a) Legitimacy and Transparency: 100 possible points.  The most important category, as ROI and remedies don't matter if the whole thing is a scam.

--> Demonstrated mining activity consistent with claimed ghs or mhs (0-20 points).  Pictures of a few racks of miners don't count.  Proof of mining can be in several ways: disclosure of mining addresses, disclosure of mining pools and workers on those pools subject to public monitoring, proof of ownership of mining capacity, or ability of the customer to control pool selection/mining.  A perfect score can only be achieved if the mining company can demonstrate capacity/hashrates equal to or greater than the hashrate sold.

--> Backed by known and trusted manufacturer or disclosed, established, major financial partner (0-20 points). While not a perfect guarantee, an established manufacturing partner or major financial backer means that there are likely to be internal controls, and even if not public, audits to prevent fraud.  

--> Mining hash rate is subject to audit/verification (0-20 points).  Ideally, a mining service that claims to provide 1 Th/s of hashing should be able to prove that the customer is getting at least 1 Th/s.  For example, a score of "20" would given if customer could direct mining to specific pool and/or enter mining BTC/LTC address directly and monitor hash rate of purchased cloud mining.  A service that mines directly into the customer's wallet is much less likely to be a scam versus a service that sends out coins from a mixer and/or coins from other customers who purchased miners.  A farm that discloses and published real time "farm" hash rate and discloses total hash rate should get at least a 10 as there is some ability to audit hash rate as a percentage of the farm at least, though the audit trail in that case requires trust in the rates being disclosed so it is not entitled to a full score of 20.

--> Longevity of service (0-20).  1 points for each month of public operation up to a maximum of 20 total points (operation for 20 or more months).  Most scammers want to get out while the money is good, so a 1+ year record is a decent (though definitely not 100%) indicator of legitimacy.

--> Peer review and response to criticism (0-20).  Subjects its service to peer review on Bitcointalk, cryptocointalk and actively participates in a generally respectful and customer-oriented manner in a generally unmoderated public discussion of its service on one or both public forums.  Answers questions raised with detailed responses, etc.  Private and/or heavily moderated forum posts do not count.  A legitimate operation should not be defensive or opaque when asked questions about its legitimacy - it should understand that cloud mining is a trap for the unwary and any legitimate operation should go out of its way to prove itself legit.

(b) REMEDIES: Ability of Miner to take Legal Action in case of fraud and/or easily exit the purchase (refund or market): 50 points

--> Resale market or buy back exists and is verified to be working with net sale prices close to cost of purchase (0-20 points).

--> Legal compliance/T&Cs (0-20).  Has enforceable contractual commitment with clear and well drafted mining agreement, with no overreaching terms, penalties, etc. (best example would be Genesis Mining).

--> Ability to enforce mining contract (0-10).  Requires disclosure of legal entity or person(s) responsible under contract, place of incorporation and legal entity name, governing law in a jurisdiction like the United States of Western Europe where a lawsuit by a consumer has a chance in hell of success).  Companies in China or other jurisdictions with virtually inaccessible court systems (to foreigners at least) would get a low or zero score.

(c) Relative ROI/Static ROI (relative to others in same grouping): Up to 50 points

To calculate relative ROI, I first compute STATIC ROI: the number of days it would take to break even on the purchase of mining hash power, at the current rate of return (minus applicable fees), assuming no change in difficulty and no change in bitcoin/litecoin exchange rates.  This is ONLY a **static** ROI and can only be used to compare LIKE SERVICES.  In other words, if static ROI is 190 days for an SHA256 coin, it is virtually IMPOSSIBLE to ROI in 190 days because difficulty will rise exponentially in that time and further reduce ROI.  However, comparing apples to apples (e.g., SHA256 mining services compared to each other, and scrypt services compared to each other), a static ROI is a good way to compare ROI possibility among competing services.  

After computing static ROI, I assign points as follows based on the number of days to static ROI, halving the points each 50 days due to increased uncertainty from longer time periods:

0-50 days: 50 points
50-100 days: 25 points
100-150 days: 12 points
150-200 days: 6 points
200+ days: 0 points

(d) Red Flags: established indicators of fraud, ponzi or pyramid scheme according to Federal Trade Commission criteria: Down 0 to -50 points (adjustment down). NOTE that merely because a service meets the Red Flags does NOT prove that it is a ponzi or pyramid scheme.  It only signals heightened caution, possibly greatly heightened caution. That is why I decided to make the red flags a negative adjustment - they take down a score but do not necessarily determine the score.   Also note that several of the "Legitimacy" items could be in the red flag category but I did not include them here because that would double count the adjustment.  These criteria are adapted from the FTC's guidance on avoiding ponzi and pyramid schemes.

--> Repeated problems exist with withdrawing payouts over period of more than a week (-20 to 0 points, negative adjustment indicates possible ponzi scheme).

--> Below market rates per ghs/mhs and/or above market payouts promised (-10 to 0 points, negative adjustment indicates possible ponzi scheme, pyramid or outright fraud).

--> Extensive reliance on MLM, resellers and affiliate marketing techniques for sales (-20 to 0, negative adjustment indicates possible pyramid scheme).  Especially problematic for affiliate programs where payouts are MLM (lifetime purchases of a customer and/or referrals of referrals would all be -20) or where there are substantial referral fees or substantial reseller programs (a legit operation should not need resellers since the "product" is a cloud service and there is little need for after sale customer service) which would be at least a -10.
