Closed. One of these miners mangled my finger pretty badly. I'm not happy with them, so bringing the total back to 160 shares as I don't want to deploy any more of these things.



We promised a Srcypt group buy; but the power consumption on GPUs really hurts the profitability over time.  Enter Gridseed, the first combo Sha256/Scrypt ASIC. I've placed the order for 48Mhash worth of Gridseed Asics - QTY 8 of LA6M.

If you aren't a current owner there are a few owners that are looking to sell some of their shares of earlier group buys, I will help facilitate your purchase. I think there are some offered at .25btc. Or PM me for interesting offers, we're still trying to grow the community and don't want people being left out.

Owners only, limit 1 per share you own.  0.55 BTC gets you 300kh/s of Scrypt hashrate hosted FREE as long as you maintain your other group buy shares in good standing.  If you take delivery of hardware for your other shares and want to keep the 300kh/s of Scrypt, a $14.99 per month fee per share of Group Buy #5 will apply.  We don't have an exact start date yet, but expect to be hashing no later than Feb 28th.  

Asiabtc has guaranteed shipping by Feb 20th, and promises a full refund if not shipped.  If they fail to deliver, any refund we obtain will be dispersed back to the owners.  We've done due diligence and asiabtc has been reputable, but we can not assume responsibility in the case where they fail to refund or deliver.


Who am I?
I'm an open source developer, and a Bitcoin mining hardware addict. I've run out space at several mining locations, and finally "bit the bullet" and moved into a world class datacenter. We are talking about a 24 hour security (multiple redundant power systems, back-up generators, back-up back-up generators, pre-chilled water tanks for back-up cooling, retina-scan access) professional data center. I am the Meetup coordinator for the Arizona Bitcoin Meetup group (now 110+ members strong; Bitcoin is kicking ass in PHX!!!). I've met many people from Bitcointalk and prominent members of the community in person as well. I've run a few Bitcoin related projects, designed my own Bitfury USB miner (ouch on that story), and pretty much eat, sleep, drink, live and breathe Bitcoin 24/7/365.

A full-time employee at the datacenter is a group buy owner. Our hardware is getting the coldest spot in the house, and will be well supervised! No more intense heat, fire risk, angry wife, or surprise electric bills. Let us host your miner(s) in an ICE COLD datacenter.

http://coinninja.com/0312afm-Phoenix-NAP.jpg

This Group Buy Includes:

• 8 Gridseed LA6M Units
• Free Hosting as long as you as long as you maintain your other group buy shares in good standing.

Terms

Payouts will be paid weekly. Hosting is FREE as long as you maintain your other group buy shares in good standing.  If you take delivery of hardware for your other shares and want to keep the 300kh/s of Scrypt, a $14.99 per month fee per share of Group Buy #5 will apply. As these units share a common control module, it's not possible to take physical delivery.  We expect to run these units for several years. Non-payment of hosting fees/deficit will result in forfeiture of ownership rights to the hosted hardware. Any and all payments are due when invoiced; 30 days late constitutes default and will result in forfeiture of your fractional ownership.

How to Buy

Current owners only send BTC0.55 x the number of shares you would like to the common group buy payment address:

Do you have any info on LA6M - is it just 2x LA3M grouped together?

Here's the technical specs from the Manufacturer
LA6M - 6MHS scrypt+200GHS SHA256.
20XUSB cell, 1X controller,4X 12V industry adapter,20Xmini usb cable,20 12V power cable,1Xusb hub,1Xmini usb cable,1X5V usb adapter

Are you gonna run sha with it too or just scrypt?

Scrypt only, it's not power efficient in sha256 mode.  The performance characteristics in Scrypt mode allow us to make this offering with ZERO hosting fees.

2 shares to 1DAemoNXFNQxeDQAeRdEg245WvYsCfdgE9

Do you have parking?

Same question here. I'm curious what the angle will be before deciding on jumping in :)

And will we be paid out in a certain altcoin or will it all be BTC?

Since this is scrypt, with which coin will you make the payout?  I would vote for doge!

Middlecoin would be the easiest, then we could just pay in BTC (and you can always go buy whatever alt-coin you fancy).  We've got the monster rig from Group #4 to do some experimentation until the Gridseed arrive.  I wouldn't be adverse to having one or two of the rigs pointed to Doge. It's open to owner input, we're a small enough group where we can come to a consensus.

Are you using cgminer? I know there are a few others but, CGWatcher has coinchoose API integrated and most of the coins added so that you can use it to define your own switching parameters. You just have to write the bat files to kill and start each coin when the triggers are hit for the swap.

This way, you arent depending on a coin pool to make your decision, you can choose the best pools to mine on for each coin and set auto payouts to the exchange for autosell.

Middlecoin would be the easy way out... a CGWatcher style solution would require a bit more work to monitor and make sure coins are being sold, but maximizes profit.

Let me start with one share. If I have more to spend in the weeks to come I'll add more shares probably ;)

So I'm supposed to get another grey hair grown over pre-order.....

Are those asics already paid for? Did asiabtc already deliver anything to customers?

Of course we paid for it all up front.  They have been shipping these in China since November, they are just now hitting the western market.  Asiabtc has been delivering, check out a review https://litecointalk.org/index.php?topic=13314.msg111293#msg111293 and check his sales thread here https://bitcointalk.org/index.php?topic=421921.  They may ship out as early as Monday of next week, and asiabtc just posted a screenshot of the modules running at 550kh/s each.  If our's are all able to do that we would be looking at 99Mh/s for this Group Buy....pretty awesome right?

Thanks for the links. I can't seem to find any place on the net where you can order them? How did you place the order?

Sent amount for 5 shares from:

Please watch out, something went wrong with blockchain wallet browser plugin. I wanted to make 1 transaction, but it sent 2 transactions and I didn't have enough coins on that address for both. I am not sure if only second transaction is going to be invalid or both.

 

We ordered direct from asiabtc.  They haven't setup the retail channels yet. You can also get them through Taobao or Aliexpress.

OK I see the first transaction went through as expected:

https://blockchain.info/tx/b62deafb2a48e013e3731b1fe1ed1c348b7cd98d1975806fa88873e97e2e0f33

Sorry, something went wrong with either shitty plugin or I was too easy on a trigger and double clicked somewhere I shouldn't have...

Anyway, I'm interested in 5 more but I already burnt myself a bit in  asics arms race... It looks like this is the right moment for scrypt and I believe you did the due diligence right, but do you have any estimates on:

number of already delivered devices / gridseed chips ?

number of orders in near future (say next month or two) ?

It needs to be simple, the miners have their own control unit that works with a cloud interface, what about http://clevermining.com/?  Right now the Group #4 rig is on middlecoin, does anyone have historical data to compare return from the various auto-switch pools?

With these possibly being much higher hash than originally advertised... are we expecting to see 1/160th total hashrate per share or still locked at 300KH/s?

We'll run them faster and the group will benefit, just like we do with the Antminers.  Depending on the effect it has on power consumption we may have to charge a (small) fee, but it would be well worth it.

No experience with clevermining but middlecoin is open and transparent and all group buy owners will be able to easily monitor everything.

I am just waiting for my BTC to come through and will grab some shares

This guy is going to test several auto-switch pools. Unfortunately no historical data yet.

https://litecointalk.org/index.php?topic=15124.0

Just looking at middlecoin miners... if this scrypt ASIC can indeed push near 90 MH/s when it arrives, that matches the fourth fastest miner currently on that pool.

Last 3 days he has averaged almost 1 BTC per day. Easy calc 7 BTC per week divided by 160 shares is BTC0.04375 per share. If that rate can hold constant (oh to dream) then this is a 90 day payout for ROI roughly... by payout week 12 we should have more than what we put in.

I'm in for 4 shares.

Why not divide the hashes over several auto-switchpools?

Thank you, MWNinja, for letting us participate in another group buy.

I have sent you the money for 2 shares: https://blockchain.info/tx/1c87391ad8182718b76712c8805b704950cae48272795a93325e21bc15710fef

Please, write down 1A8VRiALKLa26aB2zRzxcjQHMeUBWM5H4A instead of the first one that appears there, so I can easily track the earnings from this buy.

I think Middlecoin is the best option, so you don't have to care about what coin to mine and then about trading it for BTC. I personally use Middlecoin for those reasons. And, as you say, if people prefers to have another currency, they can just buy it after receiving their BTC.

MWNinja is 100% trustworthy no doubt but Im sure there will be some users that would like to see current earnings etc and do calculations for themselves - I think several switchpools will complicate the matter and make the dividends less transparent.

Hi There:

In for 1 Share please (sent payment for share in group #4 already):

I may send for more shares depending on asiabtc and sale of LA3M

0.5 BTC for 300khs: Am I right in thinking that it would take 2-3 months to break even?

I don't think it's that complicated, as long as the pools have publicly available stats for each participant (like middlecoin or clevermining and not like hashcows). You would just add a couple of numbers.

The better question is why use multiple pools if there is sufficient experience/knowledge in the community as to which pool is the best. It appears that the current leader is middlecoin (their stability issues notwithstanding). Until that changes is there really a reason to experiment with 48 (or more) megahashes? Clevermining looks nice but I'm getting only 75-80% of middlecoin rate in my own experiment (several 270Xs pointed at different pools).

Possibly 550kh/s or more per the firmware spoken of recently...

3-4 months depending on luck and possible exchange rates. But consider there is ZERO hosting fees for the life as long as you have good standing in GB#4.

Consider that after the ROI this is basically free BTC weekly...

Thanks for the insight, daemonfox!

not with scamcoin

you can teorically break even in one week with one of them lol

I'm not in this GB but wanted to throw in my 2 cents about the pool.  What about coinex?  It won't auto convert but there's an exchange built in where you can convert and that way you can contol it a bit and try and catch spikes.

Not yet; they were finalizing the firmware and are expected to start shipping out Monday.  I'll let everyone know when we get tracking.

Updated the owners list, 79 shares to go.

As long as you own in any of our previous group buys you are welcome to buy here (limit one per share owned).

All of our testing is confirming that middlecoin pays out the most.  We'd rather not have to deal with exchanging if at all possible, it adds complexity and security risks.

My back of the napkin says 50 day break even ~ hence I am buying a large number of shares.

I'll update the owners list later tonite, been dealing with some cooling issues in our new spot.  We made some adjustments (and took all the doors off the cabinets too) and now everything is running icy cold as it should.  From looking at the payment address, I'd say we have roughly 50 shares left.

Thank you. Ahh that makes more sense.

Hi ninja:

Just wondering...were you part of Jack Dai's (asiabtc) bulk order that went out a couple days ago?

If so, the units should be arriving soon.

We have a DHL tracking number and are expecting delivery Friday as long as customs goes smoothly.  I hope to have us up and hashing from the staging area this weekend (some learning curve as these are new to us and the instructions are largely in Chinese).  We're looking at March 1st for the first dividend. 

We still have to figure out how we are going to deploy these at the data center, so we'll be experimenting with cases, shelves, and other wild ideas (zip tie them to the cage wall?) Install will be a week from tomorrow (we need to have some circuits installed).

Ok, sounds good.

As I'm sure you're aware, there are ton of resources here with respect to setup and firmware and in the wild testing:
https://bitcointalk.org/index.php?topic=421921.0

If you are going to run solely scrypt, the units will not get too hot. With respect to spacing, you can remove the fans on each unit as long as their is relative airflow and you might even be able to get away with removing heatsink too (they were made with the expectation of dual hashing which is why they have both in the design)--only scrypt hash mode. One person--just, just--fit ten into an ATX, but that was with fans and heatsinks on. That should be a good barometer of your spacing requirement. The very rough and ready math tells me you could fit 20 into the same space with good airflow. One novel idea I've heard batted around is throwing each unit in a four inch PVC pipe with airflow at either end.


PS if you have better communication with Jack, can you plus one on a future bulk order for me? They are super disorganized over there and individual buyers have had a lot of trouble getting processed (which is why I pulled one of my recent orders).

Please correct me if I'm wrong but according to my calculation (based on the scrypt rig on group 4 performance), it would take 120 days for this unit to break even.

http://www.middlecoin.com/reports/1PNmf8jPm8YPs7svGhTkAULWsKR9H2z5Xx.html

5000 KHs would generate .065 BTC a day

->>
300 KHs would generate .004 BTC a day

for .489 BTC , it would take 120 days to break even

It's just my estimation. Any input/feedback would be appreciated.

two more, I'm at five shares now!

Looking forward to the first results!

We will see if it holds true but... the newest firmware has these pegged at 550 to 600 KH/s so... you may be looking at a 60-70 day ROI... especially with no hosting fee for life.

Our miners were delivered, but we only got a partial shipment. We are short 40 miners; I'm pestering the shit out of asiabtc about our situation and I believe they are going to fix it next week. I'm on a plane home now, and will start setting up the ones that arrived late tonite.

Thanks for reserving.

Well, you still have 36Kh at this point, which is good. But man, they are super-disorganized over there (full disclosure: I pulled my order).

Ask Jack if he'll throw in a LA3M for you and I'll buy it at a $100.00 + premium.  ;D

How many shares left?

Only 20 shares left.  Last call everyone as we are live hashing and slowly but steadily deploying these.  They are a bit of a pain in the ass with a ton of cables, and the software is still pretty crude (but its going to be freaking awesome).

They don't mine for shit at too high a difficulty, so middlecoin wasn't working too well.  We are mining Dogecoin now. 

Anyone knowledgeable about setting up and running our own private pool please step forward.  I'll be installing a dedicated SSD server next week for the project.

I've been looking into different pools with autosell options, besides Middlecoin that throws everything into BTC but isn't that "open about it" and pays out after a day or so, I've found these two. I'm testing with both of them atm:

https://www.megamultipool.com
https://ultimatecoinpool.com

The one I kick every coin (except DOGE) to Cryptsy and autosell them for BTC/LTC, the other has a working autosell function built in.

There are probably tons more of these but I'm trying these now to see how that works out. I do expect 30 of those 5 chip things at home next week so I'll be doing some testing with those too.

I'm doubting whether I'd rather buy 2 ANT Miners from sushi's upcoming sale or up my shares with 3 more in this Groupbuy to 8 (don't have enough other shares to buy 6 more shares instead of the ANT Miners) :)

Could always throw a few on alternatepool and see how it does. Pool hashrate is low though

Sent for one.

40MHash mining Doge right now.  I'm getting everything setup to auto-convert on Cryptsy and then auto-withdrawal to our payout wallet https://blockchain.info/address/1B5HnZQBAUx4TRWE9rN3jrF7up9Rs49iyi

https://teamdoge.com/index.php?page=statistics&action=pool

We will be moving the hashrate around and experimenting with different pools as we learn the nuances of these devices.  For one thing they don't like a high share difficulty, and there's no way to specify a backup pool.  Also sometimes they just plain die and need a hard restart. 

Only a few shares are left.  I'm headed to the datacenter to work on Group #4's GPU rig this morning, and will close this group buy today.

Just paid for 1 more share.

Just bought the last 12 Shares ( or 11 if someone got 1 before the title update )

5.868 BTC sent ... let's see how these work :)

If you are short 40 of 160 and doing 40MHash with 120 miners, that is about 330K per miner, correct? Can we expect ~53MHash when it's complete?

The crucifixion of doge :)

wow much cables very hash

I know you guys are busy but any chance you can update the owner's list now that it seems to be sold out? It seems to be over a week out of date.

Thanks.

Sold out. I am working on the final list. 

We have a number of people that bought more shares here than was allowed. The limit was ONE share per share you own in previous buys. 
We can either (a) refund the coin for shares that were beyond what was allowed, making them available to other members.
or (b) you can obtain shares of group buy #4 at .24btc per share to bring up your total holdings so that you have at least one share in another group buy for each you purchased here.

We'll be somewhere north of 50Mhash. I think we can do better than the automated cryptsy exchange, using a more advanced trading strategy. 

If any shares becomes available, I'd like to reserve max of 2 shares.

Sorry about this.

Is it possible for me to take 6 more shares in GB4 = 1.44BTC and 6 shares in GB5 = 2.934BTC? This would equal 4.374BTC?

If you could refund me the difference of 9X.489=4.401BTC that would be great: 0.027BTC.

Let me know if this is possible and thanks in advance.


BTCAddress:

1PoY1bpigWqqeTkY3XErUzJvKdNubPtRVS

That will work....good solution.

I think that means I need to buy 12 more total in GB4 ? I'm easy, saw them sitting there and didn't see the rules :)

Just wanted to make sure I made ir in for this third share... my line on the OP still shows 2.

If that is possible I'd like to put myself in line for 2 as well.

well, there's 3 opened up from me for sure.

The rest of the miners should arrive this week ~ Wednesday?.  We're getting a shipment of 12 more 10 miner kits (of which 4 are for this group buy), so if anyone is interested in the extra one's (8 available, but I'm thinking of keeping a couple to run with my solar system) we'll be selling them for $2899/per complete 10 miner kit; shipped from the USA with full tracking number...no worrying about the shit I have been going through getting these in stock into the USA from lightningasic.

Bitcoin or ACH payment available.

What are the specs on the 10 miner kit?  Hashrate?

I could be interested. An Aussie on here selling complete kit for 2550 plus shipping though...

Great. Looking for the OP update and 0.027BTC refund whenever you should get the chance.

Thanks again for a great gb opportunity!

Is there still any spots available after your recalculation?

If so I would be interested in buying 1 share.

Please update.

Thanks

Could you see whether you've already added this share (https://bitcointalk.org/index.php?topic=453536.msg5313244#msg5313244) to the owners list?

I promise that with the next GB I'll pay for all at once ;)

We paid more than that....and this will be in-stock no waiting "2 weeks" or however long it takes for the Chinese to deliver to him, then him to deliver to you.

We can also make more shares available if there is interest.

I don't think you own in any previous group buys do you?  You may be able to grab some shares of Group #1 right now that some owners are trying to trade.

OK, how do I do the ACH payment for this? Other seller is dragging ass.

Also, if if you could refund the difference of the updated owner list info as outlined in earlier post that is much appreciated:

 0.027 BTC to 1PoY1bpigWqqeTkY3XErUzJvKdNubPtRVS

The owners list has been updated.  For those that overbought we split your purchase into shares of Group #4 and Group #5, and refunded any difference.

It's a complete kit. 10 miners, 1 usb hub, 2 power supplies, all cables and a control module.  They get somewhere between 3-4Mhash depending on your pool, share difficulty, and how lucky you get with overclocking. 850Mhz seems to be the best.

Hope you don't mind a pm or two to share best practices when I get mine up and running.

I'm always happy to help my fellow miners :)

I got a rudimentary live stats page up http://coinninja.com/GroupBuy/minerstats5.php
The pool we are on is probably a temporary place (although they have good operators and a lively IRC channel). 

We really should be on our own pool; we've been finding lots of blocks.

We should just mine at Wafflepool, they automatically mine the most profitable coin, trade it for BTC and send them to the miners, all for just 1% (Middlecoin is 3.38%)

I have the exchange/payout system fully automated, no point paying any extra fees.  The problem is that these miners don't do well on high difficulty shares, which is all you can get with Wafflepool, middlepool, or clevermining.  There's a lack of transparency (what coin are we really mining?) that is also troubling. We're going to experiment with a few different pools (I already tried all the easy ones that convert for us, pretty disappointing). Really though we would be doing much better right now solo mining.  I'm looking at a node.js based stratum server, looks like we can have a private pool up and running pretty quickly.

I'd be interested in getting more shares instead of selling off those extra's ;)

And poolwise, would it be an idea to do a "groupbuy" where we finance development of a specific low difficulty pool for these miners? I guess there will be massive interest for that and it might earn a nice fee for the group. Combined with some miners for the group too of course. No foul in mining ;)

I can make additional shares available in batches of 10; but since the hardware is priced in dollars we are looking at a per share price of .55btc. Still interested?

A pool of some sort is in the plans.... if I could just stop buying hardware long enough to get other things done. 

You mean with the current low BTC rate? I'll check tomorrowmorning, but I think we can work something out ;)

This is a great idea.

I would buy a couple of shares under the same conditions as #5 (i.e. free hosting).

Also interested in the pool idea, I would definitely invest given an opportunity.

 Yeah I actually might go for this too instead of buying unit now that I think about it...

Ok we have a tracking number, waiting for the package to get diverted from customs to us. 

I'm opening this back up for 40 more shares making it an even 200 shares. Offering is now .55btc

Would we still have to compensate for any differential with previous gbs?

Also I assume Canadian bank is ok for ach invoice --if I go that route (sorry still deciding as I have a feeling my wife will hate the LA3M in the house)-- as per my email?

Bought 2 (making it 4 of each GB4 and GB5).

Yes, because due to the power efficiency we are able to piggy back these on your current hosting obligation.  I'd grab the group one shares that are for sale as their KNC will arrive before the others.

I understand the wife hating it...lmfao...my wife HATES it! And we have a room full still.... always need more space and power!

Just sent BTC2.684 to complete order of 6 shares. (Total own 8 shares in the group)

BTW, how are things going with the extra units?

My miners seem to be doing reasonably well on waffle. Clevermining was not good (lots of rejects). Will try middlecoin next.

https://meem.link/i/aihtq3dv.png
Edited 2020-11-27 to fix a broken image

Thanks for your order!
We have a tracking number for the remaining units; we are waiting for them to complete their customs inspection.  I was hoping we would get them today, but now it looks more like Monday.



Looking good, what clock speed are you running them at?  We are struggling with stability issues on ours.  They tend to get some USB error and afterwards it takes a hard power cycle of the control module (and sometimes the USB hub).  We've ordered some remote power switches so we can better manage the power cycling. If the next shipment doesn't arrive before the weekend then I will have some time to work on setting up a private pool.  Looking at the blocks we are finding on DOGE, solo mining/private would be far more profitable than anything else. Also I am hoping we get updated control module firmware soon too.  As we get everything settled out, we can do some A/B testing to see what strategy is the most profitable ~ good to know Wafflepool is working now (did they lower the difficulty? it was fixed at 512 when I tried, which forced the miners to reboot every 10 minutes because a couple didn't find a share yet). Perhaps it depends on what coin they are currently mining.

850 MHz. Waffle is still fixed at 512. I've had the controller declaring a miner "dead" and rebooting all of them, although not every 10 minutes, maybe once in 1.5-2 hours. I have not had an issue with the controller needing a power cycle.

I'm thinking to try "rooting" into the controller ( https://bitcointalk.org/index.php?topic=490348 (https://bitcointalk.org/index.php?topic=490348) ) and see if there is a way to adjust the 10-minute keep-alive check to a more reasonable value.

I'm also following Raspberry Pi developments in some threads around here and once there is a solid port I'll probably cook something up with the Pi and relays to make sure that only the "dead" miner gets rebooted if the stability issues persist.

Overall I'm still very pleased. This required a lot less setup time than an equivalent GPU rig (no f$&%ing around with PCI-E risers), is much quieter, and the whole thing draws only ~80W at the wall (1/15th of a GPU setup).

Update for any newbs wanting to join us:

Given that we don't currently have any open pubilic group buys, I am making the following offer for anyone looking to join our mining cooperative.
You get 1 share of Group #2(or #3, they are in essence the same) and 1 share of Group #5 for the low price of .75BTC.
With these shares there's just one low monthly payment $14.99 you get 18+GH sha256 and 300khash scrypt.
Please send payment to 1NiNJAGi1k51pfxKsQQQisf3MMwsPU5yCc and post in the thread to buy. This offer is EXTREMELY limited.

^this only only for newbs?

PS I think I'm going to stick at my current shares and not get the LA3M at this point (if you haven't already sold it).

I can't get enough shares of the first GBs to get to 10 and the total cost if I were to (people taking offers at .2BTC in previous GBs) --7.5BTC-- is too much for me to sink in at the moment. Speculating instead to diversify.

Also sort of sitting on the sidelines with respect to forking and a new home purchase. I'll have a new huge cool concrete basement soon for GPUs if a scrypt fork comes.

All in all deciding to bide my time at the moment I think.

Great GBs and great organization and happy to have the shares I do.

Looking forward to an announcement when it comes from a large vendor, but I don't think this will come for another 6 months or so after regulators stamp it and venture caps figure out how to make it easy....this will turn the tide and we should see it go to 1500 by the end of 2014...in the meantime it will be a wild ride, probably sinking again to 400 with regulation news or another hack...but anyway, this should all go into speculation.



 

The offer is open for anyone.  We've been holding off on the big GPU group buy as we are watching what NVidia is doing very carefully.

OK, I see. Thank you.

And just to clarify: do I have to buy multiple of ten shares in GB#5? e.g. if i buy another two shares through trade in GB#1, can I buy only two more here in GB#5?

Multiple of 10 is for previous group buys to allow you to take possession of the hardware.  This Group Buy requires you to own 1 share for each share you buy.  So if you own 2 shares of Groups #1-#4 you could buy 2 here (because of the free hosting).  No minimum buy (whole shares only).

The rest of the hardware cleared customs today, I expect to get it early next week and we will pull out all the stops to get it up and running.  Hopefully we can resolve our stability issues this weekend.  The current batch is being moved from the staging area to the cage and we are developing a monitoring system to reboot dead miners automatically. Also a new firmware release is imminent.  And we are going to try to get our own pool up and running ASAP, with the kind of hashrate we have we can pull significantly more income using our own pool.

Thanks for the clarification. I'm on the fence buying the LA3M mainly because of the stability issues I've been reading about as I have no time to babysit while I'm at work or at home; really curious as to the results of the firmware test. Will definitely buy a unit if the stability issue is solved via new firmware and if those doubled hashrates that were posted somehow prove to be a reality (if they are, someone is probably protecting that secret).

If you do go to a private pool, can GB members get on that with their own equipment?

As discussed via PM, here the deposit of 0.45 to reserve another 5 shares. Rest (2.3) will be sent as soon as I have them.

Thank you.

Sorry for all the questions...if I grab another another two bringing my total to 10 overall, do I still get to take possession of antminer? or do all ten have to be in the same GB?

 :)

We should probably power mine AUR for 24 days :)

We still havent got paid out for this GB this week right? I just want to make sure

We haven't paid out on this one, it doesn't have all it's hardware yet and we are still trying to get it deployed.  One of the gridseed miners mangled my finger yesterday, lots of drama with the install. We are continuing the install today, and more miners are expected to arrive tomorrow.  These things are a royal pain in the ass to setup in a constrained space;  I would rather work with GPUs. Watch out for those fans...ouch.

Plus there's (according to the statspage) only 1.65 BTC to distribute. No problem rolling that over into the next week :)

Sorry to hear that, thanks a lot for putting so much effort into installing these.

We are now solo mining doge in our own private pool. Give me a few days to work on getting the rest of the pool software setup so I can publish an API back to the coinninja.com website. Our pool is totally DDOS proof (it's behind our firewall).  It's nerve racking waiting to hit our first block.

+1

Please open this up to your owners so we can help... I have my own gridseed now as well as my GPU and I would happily mine at our DOGE pool.

Was able to source a pretty cheap LA3M.... Will arrive in a week or so.

Same here, I have 40 of those badboys in order and unless there is a fireware update that fixes the problem that they can't handle high difficulty I'm looking for a nice pool to run with. Doing it on our GB pool will help the group and help me getting better results!

I registered a domain for the pool, so we are totally intending to open it up.  http://www.coindesk.com/coin-miners-dogged-mining-pool-security-flaws/ this kind of stuff makes me a little nervous though; we need to take some time to ensure we can properly lock everything down.

If you would be open to it, I can point a few people your way that can help in this matter... even if it is just answers. I know a few pool operators that already have a ton of experience going through these types of fortifications.

Hey Ninja,

This might help the cause:

I gave up on trying to stuff them in the cab (was doing 30 per 2U space).  We now have them on top of our cabs, it looks totally awesome.  I'll try to get a photo once we deploy the remaining 40.  Cases would add too much additional cost.  We already had to buy remote power strips to try to manage the resets.

I'd love to hear lessons learned from running a pool.  I've run some websites before so I know the basics and we have CDN bandwidth for any static content.

I'm thinking the front end, stratum, and database/coind all need to be on separate servers.  We can load balance the front end if we get huge, and add additional stratums to improve user performance.  It's really tempting to throw the machine on the DMZ and just roll with it, but it's probably best to be cautious.

We mined our first block, a bit of a crappy one with only 8661 doge; but at least we know the pool is working!  http://dogechain.info/block/467645b8e15aad97418890956111aaa9701323deb7ee81ea09dd43bb8d7d69ce

Yay! A win is a win.

As discussed via PM, here the rest (2.3 BTC) for my 5 reserved shares.

Dividends for all of my 7 total shares to this address please: 16HTJx4cWsEP2GeLHhEWrTVSaFnmXwVmXT

thank you ;-)

so quick question... you on the modded cpuminer with the power fix that makes these ~8W per unit on scrypt?

Also, I figure you are on Linux so... here ya go...

https://github.com/dtbartle/cgminer-gc3355

nice cgminer 3.7.2 with gridseed support and full stats minus temps (guess there is not a sensor?) and has the same power fix so ~8W per unit.

We are using the lightning asic tp-link controllers and a remote power switch to power cycle when the USB bus hangs.  Does a PC platform give you much of an advantage performance wise or stability wise?  It looks like the tuning options are better, but how is the stability?  The tp-link boots up pretty quick, I'd hate to have to keep cold-starting a server/pc to recover the USB bus. I guess we could probably root and install this on our TP links without too much difficulty. 

We're going to have to put in a couple of servers to do the pool right.  The front end and stratums will be on 2 different VM's on one server in the DMZ, and the database and coindaemons will be on the other on our LAN.

I am not using a USB hub so maybe it is mostly a hub thing... but I have yet to have a single hang up once I was hashing away in cgminer... but again I have a single unit not a whole stack of them.

My understanding from other posts thus far is people are struggling with your hang up issue because the included hub is shit... SHIT. Apparently... it may not be providing enough STABLE power and when one device goes out, the whole hub has to be restarted. I DID experience something like this in my initial testing playing with the miner applications... the USB must be unplugged and plugged back in (or power cycled) in order for the miner to be picked up again... this arose when I was playing with frequencies to get the best rate. The reason you have to power cycle the HUB is that the board itself on each device draws ZERO power from the PSU itself... the damn things will mine on USB power alone so any fluctuation in temp and hashrate can cause a power spike... overdrawing on the hub... causing the hub to fail and require the disconnect and reconnect of the device before hashing will start.

Some have chosen much higher quality hubs with better peak power performance which seems to resolve these issues. So far since I found my best settings... I was dual mining on Win 7 64 bit with my unit... zero hang ups... 7 GH/s SHA256 and 330 KH/s scrypt. I do not have this on my KILL-A-WATT yet but when I get up in the AM and find I have had no stability issues with the cgminer 3.7.2 for scrypt, I will start them again on it to get a power draw in dual mode. Dual requires one cgminer 3.8.5 miner for SHA256 and then a second minerd launched with the --dual flag for scrypt.

FYI I was able to push mine to 1000 clock in cgminer but didn't like how slowly shares came in... 900 settled back to a good rate and has me at 383 KH/s in cgminer. These little work horses have a TON of headroom... the firmware is sadly very flimsy and can't handle the big guns yet... time will tell if we can double their performance.

....hoping to pick your brain once I get mine.

I now have one LightningAsic with TP-Link, and two "generic" sets with the wiibox. Both controllers are crap, but the TP-Link at least works and is in English, I couldn't get the wiibox work at all. Eventually I hooked up the "generic" sets to a PC and I'm using cpuminer (can't get cgminer to work with Windows COM ports, will try Linux later). Anyway, I can now compare TP-Link vs. computer-attached solution.

TP-Link has a decent UI (with some minor quirks) with quick status/hashrate overview. That's pretty much where it's advantage ends. It restarts miners every 1-2 hours on wafflepool (~330Kh/s per miner avg), and is almost unusable on clevermining or middlecoin (restarts every 10-20 minutes). If you try to connect more than 10 miners to the box it is restarting miners more often and it also seems to become less responsive, just not powerful enough I guess.

Cpuminer on Windows lacks hashrate stats and I need to run a separate cmd window for each miner, so it's a bit of a hassle (cgminer would be better). However the miners now are running stable for nearly 24 hours at ~340 Kh/s on clevermining, 2% reject rate. Handling 20 miners was not an issue, zero CPU usage on a cheap Celeron, just a few megs of RAM per instance of cpuminer, so it can certainly handle a lot more than that. My next step will be to test it with Raspberry + cgminer + a relay to toggle USB hub power remotely (optional - if the next few days show it to be necessary).

I'm using this now:

https://litecointalk.org/index.php?topic=9908.msg138204#msg138204

Fantastic so far... rock solid and totally effortless to set up. 360 Kh/s per miner.

How many can a Pi handle? This looks great and I can add it to my Pi distro.  I only have a couple of Pi's though, so we will need to order some more of them. We have an ubuntu (sick little i5 microITX rig) machine that is running our private pool, and we will be adding 2 dedicated 1U Xeon servers to take the pool public. For now we need your hashes to help with the variance. Please contact me via PM to help.

I have 20 on it now, does not seem to have any issues so far. I'll try to daisy-chain a couple more hubs over the weekend and see if it can do 30 or 40.

http://i.snag.gy/vBnDO.jpg

http://i.snag.gy/hg07W.jpg

Can you remove (payment due) after my name on owner's list when you finalize the list.
And are we expecting payout tonight?

Bests  ;D

Problem with Raspberry is that it can only go 2 hubs down and that it doesn't do well with usb 3.0.

Have 22 on one now but so far except for one that doesn't send shares it's looking well. I've ordered better hubs from china and expect them next week. Currently fixing my last set of 10 and see whether I can get the Pi up to 32 with my setup. It doesn't work well with hotplugging 10 at a time though ;)

I've ordered two more Pi's and that should fix most of the problems :)

22 ? I've heard the PI can do about 50 in perfect setup :)
My distro has 200+ coming in so we'll see how they work soon in that config :)

Well my Pis were crashing more than the Tp Link, and then they trash the SD card some of the time, so remote reboot is risky.  They did run really fast on the Pi.  I tried running them on a beaglebone and it worked and was very stable, but the performance was lower for some reason.  I'll try on a linux PC next, so far my experience with these Gridseed units continues to be frustrating.

After some experimenting I think the theoretical maximum is 98 perhaps... two levels of 7-port hubs, 49 on each port. Unfortunately the "stock" 10-port hubs internally already have two levels, so can't daisy-chain those to the Pi. I left my Pi running with the 20 miners it started with, and will probably buy another one for the other 20.

Ninja, could you please check this. I should have 4 shares in GB5. Owner's list shows only 2 and I believe my weekly payment is also for 2. Thanks!

Just noticing some rounding discrepancies so wanted to ask how that is being handled... what are the rules for rounding dividend payments?

See Lines 22-25 for inconsistencies.
https://docs.google.com/spreadsheet/ccc?key=0AsVvuskew8TmdFFrLWZXbi1SQUk3SzFhcWFXbXVRd3c

Theres some rounding (set to 5 digits) in my Google payout spreadsheets. The rounding is a little weird, as it will show a rounded per share value, but then use the full precision for calculating the actual payout, which is then rounded to 5 digits. 

I'm still a bit confused after our previous PM exchanges... the GB 5 page says 0.01483 per share * 4 shares = 0.05932, but the payment that came in was 0.0593.

On the other hand for GB 4, each share = 0.0186598190 * 20 = 0.37319638, but I got 0.3732 which is slightly more than I'm supposed to receive.  ???

Have you tried this?

https://litecointalk.org/index.php?topic=9908.msg139447#msg139447

I don't know if it works since my Raspberry didn't seem to crash before, but others are reporting it fixes the issue.

You are correct, thankfully there's a blockchain that has all the history! I will fix it today and send your missing payment.

Got it, thank you!

That seems to have done the trick, my miners at home are now stable.  We will be procuring 8 Raspberry Pis for this group buy.  Hopefully we can recover the cost of the Pis by selling off the TP Link controllers.

In an effort to maybe increase total earnings since you have had to come out a bit more in cost to get these stable... I have found these gridseeds can easily run at 850 frequency and hit 383 KH/s without a fan and no worries of overheating as long as their is some ambient airflow. We seem to be running at about 300 kh/s now per device on average... as long as you have either the optmized cpuminer that runs ~8w per device or cgminer, you should be able to get those kinds of results easily.

That would be a jump to over 61 MH/s on average. A 27% increase just by changing to 850.

I'm going to need your help when I get my LA3m. I take it I should order a raspberry pi and toss the controller I get?

Bump  :)

Hello Fellow Owners.

You might have seen the IPython notebook revenue estimator that I posted in these forums a few weeks back. I've now turned that into a standalone website that enables you to estimate your current returns from participating in the group buys.

Have a look at: http://coininaflaskopenshift-franktoil.rhcloud.com/

I think you are doing something wrong with GB5. Why is its "Incremental Revenue so far" negative? GB4 looks about right.

I'll have a look....

OK, I think I have an answer, albeit not a particularly useful one.

After PMing with MWNinja, the information displayed in the "Total BTC Paid" field for GB5 (which is what I scrape) comes from the API of the mining pool. So far, so good. Unfortunately, several pools have been tried at first in search of maximizing income, and the revenue from other pools isn't included in that field.

That's why you are seeing negative incremental income, since the "Total Earnings" field in the weekly field includes all income.

MWNinja suggested incorporating the info from the blockchain into my calculation (via json output from https://blockchain.info/address/1B5HnZQBAUx4TRWE9rN3jrF7up9Rs49iyi ). That is (of course) quite possible, but my scraping code does not deal with that at present.

Let me see what I can do but no promises. (This is a volunteer effort, after all. If you have Python skills and are willing to help out, I am fine with giving you access to my git repository...)

MWNinja,
I'm sorry, but I'm not seeing my name on the owners' list for 1 share?
A purchase was made/posted here on Feb 17th.
Thanks.

Selling two pairs linked shares in GB4 and GB5 for .45BTC each

https://bitcointalk.org/index.php?topic=491659.20

Fixed and dividends sent. 

Were you able to find a good multipool with low difficulty?

Clevermining has been doing a terrific job the last few days. Sometimes peaking above 200% for LTC!

of course i lose half my hashing power on one of those days because of a technical issue...

This group is temporarily down for maintenance.  We are improving the packaging, removing fans, and updating the controller firmware.  We should have everything back up and running in a few days.

We are back up and stronger and more stable than ever.  In light of groups #1 -#4 winding up, we will have to charge a small power fee to this group buy for members that do not have shares in groups #6.  This will be our actual power costs, nothing major, around $2 per share, to be billed when the power bill arrives. Owners that have shares in group #6 to cover this will still get free hosting.

Great. Thanks.

Thanks also Ninja.

I think I chose one of the worst possible times to get into mining, but hey' that's life.

Despite the headaches, long nights, and financial loss.... I would still do it all over again. I wholeheartedly believe in crypto-currency, and mining is how you get to have your "vote" and actually participate in the system.

Fingers crossed that May will bring some reasonable gains to take away some of the pain.

Yea guys..

It feels like running on machine-guns armed with a knife but  ...

"Tree of liberty has to refreshed by the blood of patriots ..."... (Disclaimer:  Not an 'mErican, so forgive me if I'm not quoting him right)

I'll be holding the line until I'm left without my stash or electricity :)

We're thinking the smart move is to ebay as many of these as we can right now and switch the group to one of the A2 60Mhash miners.  If we can sell them quickly enough we should be able to net enough funds for the upgrade.  What sayeth the group?

I would be for it. Any thought to giving the group owners a chance to buy some first then eBay?

Yes.

We have 200 of them, right? Should be enough for more than 60 MH/s, e.g. something like this:

http://zoomhash.com/collections/top-sellers/products/88-000khs-95-000khs-a2-scrypt-asic-stock-in-hand

GAW is hocking the individuals for $80.

We still have 160 correct? Best case scenario... you can get them all sold for about $11K and we can all benefit from a 50%+ increase in hashrate.

Don't forget to take into account Ebay fees, Paypal fees, taxes, etc.

This is exactly what I was contemplating with my own mining operation before i realized I had no money left for such a purchase.

Don't know if you want to work with Jack again, but he is selling 75M for $8500 USD, and 90M for prob just a bit more - May 15 ship, I believe.

https://bitcointalk.org/index.php?topic=421921.0

Also, guy out of Holland, username blaater, selling 60M right now for $9150 USD

https://bitcointalk.org/index.php?topic=585169.msg6505894#msg6505894


You can probably find a lot of buyers for the pods (including me!) at 60 USD, which would would prob net enough to
get you a 90M, if you went that route.

Any, I'm all for the purchase. I say start selling now, and then by the 15th you should have enough capital to make the order and have it shipped out.

+1

Ok we have an auction going up today. Hopefully we can raise enough for a nice upgrade before the prices plummet.  I'm giving first dibs to current owners, $900 shipped for a complete set up 10 with power supply, hub, cables, and controller.  Send me a PM if you are interested.

any news about selling?

there are definitely buyers out there for 900 full kit.


Name your price Ninja and I'll see what I can do to help.


We really need to leverage these units in the next week or two; if you price these to sell at $800.00 for full 10 pack kit, we can get a 90M plus a 30M for 120M and keep this GB going.

If everything goes well, we should ROI in two months, before Titan hits the market, and if things go really well, Titan may not hit until September, and we have two months profit taking.

I would then say Flower Techs Scrypt-N Asics will be out and we should jump onto that.

Alternatively, we can all say our goodbyes and pocket $80.00 per share on the total sale price.

It looks like you have managed to sell quite a few from what I can see--that's great!

were you able to get the $900.00 price for all 9 that you have sold?

If so, I know of 75M rigs shipping now for $8000.00--let's get back on this train!

And for the ones that are left, have you tried switching to rpi's with Minera? (https://bitcointalk.org/index.php?topic=596620.new;topicseen#new)

They autotune the gridseeds to the most effective freq.

As long as there are still gridseeds running ofcourse ;)

I'm no shure about the Grids being sold. The assumption is based on the stats-page i presume but a week ago most of the miners were also down. A few days later they suddenly came back up again. Coinninja is keeping quiet while he was always quick to communicate. I hope he is not running away.

Yeah, we also should have had volt mods done on all these guys too--would have amounted to an average of at least 20 Mh/s over 160 units extra.

If these are not sold, I could have someone turn this around in 2 days for $10/unit.

$1600 for an extra 20 Mh/s. Not bad if you ask me....

Anyway, get back to us Ninj.

We've sold a couple of invidual units so far; no luck in selling the 10 packs.  We've been slammed with a move, and equipment failures.  Looks like a breaker is thrown at the Gridseed warehouse space, I'll head there after work and get them all back up and running.

Our seeds have been defanned and are running on the latest v3 Lightning Asic controller that is very stable and supports automatic individual overclocking.  We're also looking at the voltage mod; its a ton of work (we would do it, shipping time would be too costly).

A ha.

I know you are a busy man, but I say sell, sell. And once you get the hang of it and if you have the right gear, the voltage mod takes about 5 minutes per device with two people assembly line style. I'd make mods on all units, and you can get rid of modded units for $80-100 per unit. Non-modded to sell them fast it's now like $65-80 per unit.

Name your price for full kits and and/or single units. I can have my friend who runs a fairly popular web store here in Canada advertise on your behalf (for small finder's fee) and/or if the price is right he can buy wholesale from you.

If we can get rid of these units now, we can keep jumping through the technology and surrounding circumstances should change enough that we find profitability.

Send your offers for these to me via PM, we are still trying to sell them here, on ebay, and on craigslist.

Any update on the quantity of gridseeds sold and on what we'll upgrade to?

We've sold 14 so far; there's not a ton of market demand and ebay is VERY competitive. We're working a deal for 30 more right now.  Ideally the move is to increase our overall hashrate, so we would be looking to upgrade to A2 terminator based devices.

Have you tried Amazon? I sold a bunch of Gridseeds there for between $90-100 most recently. Mine were unmodified with fans though.

24 Gridseeds sold total.  We hope to be able to upgrade to a 60MH A2 based miner in the near future. 

The grids are temporarily down as they are being relocated.

Thanks for the update! I hope we can get something else hashing soon! :)

I tried for ya man, but there's very very little demand for these units...also, the reseller had issues with what you sent as the heatsinks were damaged by the screws.

The good thing about these guys I guess is that they use very little power, so they'll remain profitable for quite a while longer, then maybe you can liquidate for $10 bucks a piece or something in a couple months.

I wouldn't bother with an A2 60Mh/s; I'd get 10 blades instead and mod them for the same hash power (~$6,000USD; ~$5,000USD or less by the time you buy them). The price point and power usage on the blades makes these the best bang for buck right now. The A2 chips are power hungry and more expensive option unless their price drops to <$4,000USD for 60Mh/s in the next couple weeks.
 
(Although GAW Miners dropped the price of their black widow for a week last week to $809.00, and that was briefly best bang for buck. I bought two for $1600.00 to get 28+Mh/s)

If it drops again, I am on alert from them and I'll let you know.

GAW does hosting for 2,5% of the hashpower. With a bit of luck we could just get a little farm there. Problem is that they don't have any SLA, on the other hand, we lose the hosting costs.

GAW miners are fine, however I have heard quite a few bad comments about their hosting service. It seems to be down often.

We found a new home for the gridseeds, internet is up now, just waiting for them to turn on power to the space. I'd like to invest the group's balance ($1500) toward some new Scrypt miners fairly soon.  If a couple more 10 packs of grids sell on ebay, I'll be able to order us one of these:

27+ MH/S - UNBRANDED - THE FALCON BY GAW MINERS - ASIC SCRYPT MINER - FREE ZENCONTROLLER (SHIPS SAME DAY) 2,349.95

But I heard the power usage on those GAW things is horrible.

It is bad, nearly double that of Gridseeds (per MH/s). Ninja, have you looked at SilverFish miners, like this one:

http://minersource.net/collections/frontpage/products/silverfish-28mh-scrypt-miner-440w-ships-6-18-14

It's more expensive though, so might not be worth it considering the likely short lifespan.

Monero is on the rise. Maybe we should think about switching or making a new cryptonote group by ?

Better price here:

https://btcfarm.org/?product=silverfish-blade-28mhs-scrypt-miner

I'm still very happy with my purchase of two (2) Gawminer Black Widows for $1600.00 = 28Mh/s (you can't get this deal anymore, however), despite the higher power needs.

I say you should sell the remaining gridseeds for $20.00 each and then ask the group for a bit of extra money to fund a pre-order buy of a mini vaultbreaker.

http://www.gawminers.com/products/shipped-pre-order-batch-1-the-vaultbreaker-mini-250-mh-s-asic-scrypt-miner-w-free-zencontroller/

20 each is very very cheap, I'd think we'd go a bit higher than that. For that price I'm even interested to buy a set or two.

...which is why we should sell for $20.00 each.

each week these don't sell, the closer they get to paperweights. We need to liquidate as many as possible, as quickly as possible.

You can get a modded blades right now (6.6Mhs) for $650.00 or so, in a week or two, even less.

$30.00 might sell quickly too, yes, but if you throw $20.00 a seed out there on the boards, these will be gone and shipped in 48 hrs.

Right now, $70.00-$90.00 USD per Mh/s is about where the market is at if you know how/where/when to buy.

I personally think maybe we should try and sell what's left for $25.00 a seed all that said, order a mini-vaultbreaker, and take a chance that they will beat KNC.

https://www.ehsminer.com/product/ehs-asic-scrypt-miner-vi/

Interesting... $10 per MH/s and based in Colorado. No idea what efficiency is yet but this has potential.

I wouldn't want to take the risk in buying from a new company which promises hardware considerably better than what all other companies are producing...

Not sure what our budget is, but GAW's Vaultbreaker mini seems like the best deal at 25$ and 2.5 watts/Mh, considering that the company delivered efficiently for the current generation of miners.

I would be strongly opposed to any kind of pre-order for this group buy. If we want to mine let's buy hardware that's available now. If we want to gamble count me out :)

Ninja, I PMed you an option you might be interested in.

Agreed. Let's keep things down to earth.

I look at it differently I guess:

We stay on this train of gear forever, always trying to get closer to ROI, or we take a gamble to surmount the ROI by pre-order.

If we all want to go the route of existing gear, this is currently the best deal out there:

http://festival.zeusminer.com/?seller=olympus-force40-off-thunder-x3-28mhs1-raspberry-pi-sd-card5coupons-package-10999

28Mh/s for $1200.00

Ninja, I would order one right away with the capital you have.

Where do we sit with respect to selling?

My friend zig hash just sold 30 oclocked pods for $50 each. I'm sure we could sell ours for $30.

https://bitcointalk.org/index.php?topic=656105.0

Ninja, I'd like to make an ad and get these liquidated...

And a status update would be nice too.

With the current difficulty with ROI and the very nice Antminer S3 I'd be for a switch to BTC mining. With a batch of those we'd at least start mining again. At the moment nothing happens and Ninja doesn't respond anymore :(

If we were to do such a radical change as switching to mining another algorithm, might as well do a share buyback and start a new group buy.

Well, I hope in that case Ninja discusses that plan with the users instead of the flash closings of the first few GB's.

I'm making an ad to liquidate on bitcointalk.

Having offers come by PM to you Ninja.

I'm still here and the grids are still mining away - I've never collected a penny for hosting them either.  We've been very busy getting our cloud ready, and it's now finally made it to closed beta today.  I can finally come up for a breath of air.  There hasn't been any action on Craigslist or Ebay for these in awhile, and the price of Scrypt machines is still falling fast. Waiting has been a good strategy here.

I'm happy to facilitate a sale in the $30-$50 each range; but so far the only offers we have had have been from scammers. If any of the members want out, I can ship your grids to you (just provide a label). 

Members only, please PM me for an invite to the NinjaCloud closed beta; we're looking for testers.

Looks like the multipool we have been using is closing down. I need some recommendations for where to point the seeds...

Here is a good overview: http://cryp.today/

Nicehash = rental where you can decide a minimum price to mine for per hash. I'm using clevermining as first pool after and wafflepool as the second one.

No one will buy these at the moment with what is out there for more than $10.

I say run them for as long as they maintain profitability and then 86 them.

We're going to switch this one to the ghash.io multipool later today to take advantage of auto-payouts (makes my life super easy).  Also the NinjaCloud will be adding Scrypt and X11 support later this week (it's in testing on our development branch), so we'll also be able to get some additional revenue renting out the hashpower. The hosting situation on this group is good for a quite some time, so we should be able to stay running (as long as there is some meaningful return) for 6+ more months.

The please remove all the crappy coins that constantly ORPHAN, it's a plague on GHash.io.

Plus, what's going to be done with the 1500 USD that we have in cash? Would it be a good one, as I suggested, to get 3 antminer S3's and at least get the money active doing something?

The S3's at least will most probably ROI.

I'd like to keep this one on Scrypt; the prices on scrypt have fallen considerably, but I believe they will continue to fall faster than the machines will earn until the retail price of the machines reaches production costs plus a thin margin.  I expect this to happen in the October time frame for scrypt as it's beginning to happen now for sha256.

Power efficiency is going to be a key factor. 

Looking at GAW their hosting prices are cheaper than the cheapest electricity rates in the world....makes me wonder how they do that? Ponzi perhaps? 

Actually i checked this myself and the rates were comparable to my electric cost... I assume that means they have a healthy margin on those machines and are just giving away the hosting at break even costs.

While I do not hold it against you for trying to keep this group on scrypt... holding the cash is allowing it to do nothing for us right now. The batch 8 S3+ went up on Bitmain for .58 BTC each (that is under $300) and hashes at 453 GH/s... buying BTC with that $1500 and then buying 5 S3+ will be adding 2.265 TH/s minimum by Sept 20th. That earns at least half the BTC cost back by the end of the year on a steady 20% increase through the end of the year. these S3s will be profitable well into 2015 and possibly later and represent one hell of a way to ensure this GB continues to make BTC.

The only other thing I would suggest, is that profitability on scrypt is just going to decrease as the ASICs get to narrower margins... if you do not feel it is worth buying something with these funds... buy BTC and split it evenly across all shares.

What daemonfox says!

I personally don't see a great influx of money into LTC and other altcoins. So we would be mainly hitting LTC through pools and LTC looks to be crumbling. In October all large Scrypt ASIC builders will have delivered. The Gridseeds we have will be completely useless by then and I would like to get at least ONE of the ninja GB's I'm in to ROI or at least get close to it. GAW absolutely sucks powerwise. Even their new Green line does. So for me Scrypt isn't a real option to invest in right now. I've done calculations on all available hardware and even with mild increases they don't ROI.

I don't think it's such a problem to switch to SHA256 since we're already paying out in BTC anyway and while we try to sell off more gridseeds at least we're getting a hell of a lot of revenue coming in from the Ant's. With a budget of 1500 USD I think that's the best way to earn back most of the investment and make a profit on top.

Plus I'd like to get more discussion in the group and decisions by the members. There's been a whole load of messages before we got a response from MWNinja with a statusupdate, I'd like to get a bit more engagement from the GB manager. We've been sitting on that 1500 USD since 23rd of June and no action there. It's the groups money and the group needs to decide what to do with it.

Same thing with the switch to GHash multipool. That's a decision the group should make or at least get involved in. Yup, it makes life easier with payouts but like I said, they orphan like hell there, I had to unselect most of the smaller coins there in my fallover pool.
I'd rather have them pointed at Nicehash when the price there is higher than elsewhere (or the ninjacloud if that works well) and with CM as first pool and maybe GHash as failover.

But mainly, get the S3's to at least get this GB profitable soon.

You accuse others of ponzi!!!

You still nots answer questions about your scammy worded S3 buy that was a lease!!  I got ignored by yous for asking valid questions you showed no proofs.

I'm working on something with some S1's that would start hashing next week (undervolted), to be upgraded to S3's when the upgrade kits ship.  Fingers crossed on this deal.

That would even be a better deal if it's cheaper than just buying the S3's!

I'm all ears!

Wills it make same claims that regular S3 did without proving?  The one that was changed names to sound less scammys on a lease?

https://bitcointalk.org/index.php?topic=715299

Ok here's what I have put together for this group's expansion:

3 Antminer S1's - $125/each
1 1200 Corsair Power supply - $200
3 Antminer S3 Upgrades = $241/each

Total: $1298

The remaining $200 is being witheld to help offset our power costs to date, so far we haven't withheld anything, despite our cost basis changing when we lost the original location.  Also I donated my remaining personally owned gridseeds to the group as well, and took zero compensation for them.

We will set-aside 20% of the group's hashrate to pay the $200/mo power bill for our operation.  Next power bill will be due October 1st; if it starts to look like we are going to come up short on power we will adjust the set-aside percentage.  Everything will be set on auto-pay from Ghash.io, so payment will occur as soon as the .1 threshold is met.  We're picking up the S1's this weekend, and will get them installed ASAP.  We have a very low power cost for the next 9 months (though its limited to about 2500 total usable watts), so I expect this group to thrive for quite some time.

Those upgrades are as specified on the Bitmain website right now? The one shipping before 20th of september?

Are those S1 going to run undervolted for the time being until the upgrades are there? Because buying completely new S3+'s will cost at current bitcoinrate 295 USD each which is cheaper then buying 3 x S1's off of you and waiting for the upgrades. Unless we'll be running hashes with them untill the 20th of september. Then it makes more sense.

And I've raised a question before about the GHash multipool, have you taken out the coins that constantly orphan?

And last one, have you considered getting nicehash as the first pool and when price is lower dan actual payout at other pools switch over to backup pools? Nicehash has usually a higher payout than straight mining multipools so it's an easy way to get 20-30% higher payouts. Even if you do a payoutround every three weeks to get to a minimum payoutlevel it's way more profitable.

Well be hashing starting tomorrow when I pick them up and get them configured.  Ghash autopayout keeps complaining about payout addresses, so it looks like it's not going to work anyways. I'm open to using any multi-pool, leasing, anything to get us the best return. 

Multipool Scrypt I'd go for:

1. Nicehash (with diff set at 256) (with minimum payout to the payout on LTC * 1,2)
2. Clevermining (with diff set at 256)

For SHA256 I'd go for this:

1. Nicehash (with minimum payout to the "average" payout on 1 Th in BTC * 1,05)
2. GHash.io

Since you're in the US you'd be better off with WestHash I think, same system.

Minimum payout refers to the payout per hash that the market at that point gives, if it drops under that it kicks your miner off and lets it drop to the failover pool. Once the payout pops up above your set minimum you'll be mining nicehash again automatically.

Regarding the average payout on BTC, I fill in 1 Th here: https://bitcoinwisdom.com/bitcoin/difficulty (atm 0.02109) so you'd end up with a minimum wanted payout of 0,0221445 BTC per Th/day.
LTC same thing, Nicehash pops up and down a bit throughout the day, I keep my miners there when it's about 110/120% above regular LTC levels.

I on average update those minimum levels every week to one and a half week, at least when there is a BTC difficulty change or a bit jump with LTC.

I don't mind getting paid every two weeks if that makes it a lot easier for you from a bookkeeping point of view, higher would be a bit too long though.

Can we please stay away from Ghash for Sha though? Let's not allow them to get near 50% of the network again.

You're joking right? I think we are well past any chance of that happening again so easily... sitting close to 200 PH on the network now... and Ghash hasn't surpassed 56 PH with current nearer 46 PH... they have not been more than 30% of nethash in the last few weeks and it would take them 40+ PH from where they sit now to achieve that. I would be more worried at how quickly Discus Fish has grown and why none of the other pools can match CEX's success with Ghash.io's output.

It will happen again for sure, if people keep thinking like you do (it's ok for me to do it because the majority of the other miners probably won't!)

30% is, imho, way too big for something that's supposed to be decentralized.

Anyways, that's not what this topic is about, sorry for the digression.

I was mainly aiming at Ghash for their extra mined coins that they deliver with merged mining. In that sense we could cover some of the electric with those coins. Eligius does merged with NMC but I haven't seen a payout there for months.

Getting a few percent extra does a lot for the profitability. I don't think Ghash will get anywhere near 50% again, so I don't see the problem there at the moment. We could vote on it?

And @MWNinja, we've been mining for a few days now. Where did we go for? And is there a place to check the results so far?

We're on ghash for now, I'll get a stats page up for everyone later this week.  I've started also experimenting with nicehash/westhash, and will probably add them to this group shortly as well.

Yous would think ninjas would do a vote or somethings.

Seem like theys worked like ninjas in the dark to get ghash.   Ninjas are silent i guess.  Seem like complete opposite as saying payout not works for them.

What should wes think ninjas would do after that S3 lease that worded like buys..... ninjas even changed that topic it seemed so scammy on words

GO AWAY! You obviously are not a customer, nor have any interest in Ninjacolo... we all read you post and know how you feel STOP REPEATING IT!

What daemonfox says here. I've been critical of Ninja before and am on top of this GB regarding management but he's not a bad guy. So please leave the thread alone if you are not a customer or won't be adding anything usefull.

How's the statspage coming? This one hasn't been updated in a while: http://coinninja.com/minerstats5.php

Ninja, would it be too much to ask to get an update on this GB? With the recent payout we'd be getting close to ROI in 5000 days so a bit more active interest is greatly appreciated.

Upgrade kits for our S1's have arrived; now waiting on a large order of thermal grease.  I'm expecting that we will have them upgraded on Monday.

No time to work on the stats page at the moment, busy building out a new warehouse and upgrading 100 S1s.  I've been testing Nicehash/Westhash and the results look good, once the upgrades are done I will move the miners there and anyone can get the stats based on our payout addr.

It's been almost a month now since the last payment, what's up with this project?

And where are the results/addresses for the Nicehash accounts?

Payment received, right after I posted this!

Thanks.

Is this GB officially dead? Received my last payment on oct. 16.
Did I miss something?

No, Ninja is doing a lot of other stuff and has stopped responding here about this GB.

I'm getting quite close to calling this whole thing scammish.

If Ninja is too busy to manage this group buy, it would be nice if he could buy back the shares like he did for GB#4.

Just popped a question in the thread of his latest business venture: https://bitcointalk.org/index.php?topic=782519.msg9600396#msg9600396

Two months ago we were promised an address where we could see mining results.

Ninja, any updates here?

He hasn't posted on the forum since October :S

It's weird, he used to be very active. Well, at least we still get paid occasionally.

He didn't die: https://bitcointalk.org/index.php?topic=782519.msg9748134#msg9748134

It has been a month since last payment now, would you mind sending them?

Thanks.

I'm going to give it until the end of the year and then he's going to get a negative trust vote. I've had it.

I had left him a positive trust back when the groups started, seemed like a nice person to deal with. I have now removed it and thinking about a neg too.

He blatantly ignores my questions in this thread.

Hopefully your red trust will kick you into action MWNinja. It's sad it had to come to this.

Same here.

It's been months since the last payment now, and still no sign of life from Ninja...

He's still here.

I received a payout. Seems kind of low considering all the delays. Has anyone else received anything? Here is the TX:

I'm in the same payment.

Received it too, the amount seems fair considering how unprofitable scrypt mining has become.

Well, afaik we have some S3's running too.

I think my neg trust is staying for a while - until we get some word as to what's going on.

None of the addresses the payments are coming from are active on Nicehash btw. So or he's moving it around before paying, or he's blatantly lying about pointing it towards NH.
I had hoped he had since the recent surge of rates with the Paycoin bonanza.

Weren't they only for group buy #4?

Nope.

Plus his statement that he'd switch to ghash.io with automated payout once you would reach 0.1 is BS since the recent payment includes a few that have lower amounts.

Hasn't been active for quite some time now. Did anyone hear anything back from him? Maybe through other channels?
