Bitcoin Forum

{Posting here, as there's increasing interest in LTC GBs and there is no equivalent LTC GB forum available}

You asked for a Litecoin Group Buy or mining contracts...so we responded with a Litecoin Group Buy!

These are Group Buys to own fractional ownership of DZ MC Ultra Power Rigs capable of 3.6 to 4 MH/s in Scrypt hashrate. Each sub-round in R20 will Feature four (4) ATI Radeon R9 R290x GPUs with 4 GB of GDDR5 per GPU. These are the Lamborghinis of the Scrypt mining world.

This LTC GB is meant for those looking to diversify from BTC Buy/Hold, and BTC GBs into Litecoin GBs. Litecoin is now widely seen as the "Silver" to Bitcoin's "Gold"-like standard, and has had massive appreciation in value recently. The network difficulty growth is also much lower in Scrypt mining.

12/11 Clarification:

** We will be doing multipool, even multi-coin mining. I listed this as an LTC GB but we will definitely be mining some of the better known ALT coins when it makes sense, as we're big fans of triangular arbitrage. Payouts will be in LTC (please leave your LTC wallet address for payouts in order comments or send a follow up support ticket) **







25 shares are available in each rig. Each share gives you 1/25th of the rig's hashrate (minus low cost professional hosting/management fees).

If this GB sells out, we simply open up another sub-round called R20B. We can repeat this as needed, as R20x doesn't face the same hardware shortages that are often found in the ASIC Bitcoin miner world, since GPUs and PCs are essentially commodities at this time, as opposed to the prototypes we all get sent (AKA as ASIC miners). Inventory is essentially Unlimited for R20x, so there's no worries about running out of GB shares.


** Each user is limited to only 6 shares per rig/sub-round (6 shares in R20A, 6 shares in R20B, etc., etc.) so that other people get a chance to own a part of the rig, and so that too much ownership/votes don't reside in any one person's hands. Purchases of 6 or more shares will be automatically split amongst multiple GPU rigs/sub-rounds. **

1 share = $212 = 144-160 KH/s for 6 months (unless there's a push from owners to sell the equipment earlier) + access to ultra low cost miner hosting at $300 per rig per month (and a 0.5% Management Fee). We will sell the unit or decide to continue running it before the 6 month mark.

This share price includes assembly/testing/troubleshooting & access to monthly low fixed costs for business insured hosting/management fees in a professional ASIC/GPU Miner Colocation Facility built just for LTC/BTC miners in conjunction with Miner Hosting LLC run by bobsag3.

==

[Per the rest of our other forum GBs, any resales at the 5-7 month mark will have the proceeds split by proportion to one's ownership of that Round's rig minus a 1.5% co-op transaction fee for handling this sale]

Share price includes funds to purchase an entire DZ MC LTC Ultra Power Rig, the assembly and testing, and UPS with battery backup. Hashrate will be split in 25 portions or GB shares.

Comparison: with shipping, an R9 R270x video card alone, capable of 450KH/s costs $220-260, before you factor in the rest of the system (case/PSU/RAM/CPU/accessories/assembly/testing/power/cooling) needed to set up and run a power hungry and noisy Litecoin/Alt-coin rig for months at a time.

Hosting and Management fees: $300 per rig per month + a 0.5% management fee, which works out to $12-13 per month per share (~$6 per share per bi-monthly payout on the 7th and 22nd (we alternates payouts with BTC rigs, which are paid on the 1st and 15th)).


DZ MC Exclusives include multiple Server class UPS units and battery banks, multiple gas generators, dedicated extra Air Conditioning plus access to 5 world class IT experts!

Note: For those wondering - R9 R280x GPUs are in too short supply at this time for us to have confidence that we'll be able to get these models in the volume we need, at the time of ordering. If R280x supplies appear to have greater supplies in January/February, then we may consider revamping future R20x- based GBs.

==

Individual purchases will be batch processed a few times a week. Please don't be alarmed if your order shows as Processing for a few days. We're still only 2 guys batch processing orders at this time and we're not at the point that we can hire someone yet just for order processing. Mahalo!

Please open a support ticket if you have concerns that your order didn't go thru after 48-72 hours. Also, please check our FAQ to see if your question has already been answered before sending a support ticket or forum PM. Cheers.

P.S.: Pictures included are representative, and may not represent the actual hardware used due to supply constraints. We may actually go to open case aluminum cases if we can secure enough stock.

Refunds: Refunds are discouraged because of the chaos caused in Group Buys, but if necessary, you will be refunded before the miner ships, at a 1.5% restock fee. After the miner ships, no refunds are available.


===============================================================================================================

NEW (10/21) Share Ownership Transfer Fee: There is now a 0.75% Ownership transfer fee if you're buying someone else's DZ MC co-op shares. We put a ton of time, money, and BTC to offer the GB community many of the world's best at-cost and below-cost deals. Refunds and share transfers cause chaos and extra work for us.

This 0.75% share transfer fee *MUST* by paid by the new owner before we will transfer share ownership.

By sending payment, you agree to these Refund and Transfer terms before purchase.

Another great gb, congrats. I just bought the hood of a lambo!

I'm in for one share.

When is this scheduled to go live?  I read through the post it and didn't really see a date. 

I see Jan 15th as a date.
I have a suggestion could you or anyone supply some ltc links for forum members.
A ltc difficulty link.
A ltc mining link.  Showing ltc price in  BTC USD  EUR.

In a sense to buy this it would help  if some could know what 212 kh hash earns in a day.

For instance most people  may not know that LTC hash rate for a video card is in khs not mhs.

I will try to post a few links.


https://www.litecoinpool.org/calc 

200 kH/s earns  about .071 ltc a day


http://bitcoinwisdom.com/litecoin/difficulty     growth rate varies

The bottom-line for this investment is a hope that ltc price raises and difficulty does not go nuts.

Is there any good site for Litecoin Calculation?

Thanks

The current LTC difficulty is 2,694
I believe this is the networks hashrate 91,832.2 MH/s

Exchange rate
http://litecoinexchangerate.org/

earnings calculator
http://www.litecoinminingcalculator.com/

found some info  I may buy a share to get into the litecoin game. I never set up  any of my btc gpu rigs to do lite coin.  I still have a gpu rig

Thomas

By using the cal that you provided

160KH/s earn 0.06 LTC per day or 1.7 LTC per month.

With current exchange rate 1.7 LTC ~ to $50

Is that right?

Thanks

Yeah, guys I love you but the economics on this are way off unless LTC goes through the roof.  Going to have to pass on this one.

well if it is 25 shares for a rig . you pay 12 bucks over head 300/25 if the share earns 50 bucks - 12 = 38 dollars back in 1 month .  at todays  difficulty .   ltc does go up and down in diff.  I won't decide until r9-r12 gets settled. if I get a buyout and divs I would buy a share here maybe 2.  I am certainly liking r17 more.   but remember this machine will sell for parts as it has great gpus inside of it. so it will have value even if all mining dies.    when I cashed in all my pc gear I sold 21 gpu's for over 4k.

The problem is that it will be tough to get ROI on just the shares.  You raise a good point the hardware itself in 6 months will be worth nearly 80% of their costs, because you can sell the hardware to just about anyone, and the hardware in question will still be top contenders in 6 months.

I just wish there was an easier LTC exchange to deal with the current options are pretty much horrible.  The only reason I would take part, would be to bank some LTC, and then get some of the BTC back when the hardware is sold.

Have you considered using Multipool - always mine the most profitable coins?

Just wondering if it really makes a difference.

no doubt roi on the mining alone almost certainly won't happen in ltc terms but maybe it could in usd.   but I am thinking you always can get 70 to 80 percent back on the pc/gpu aspect.  so this would not ever really zero out .  it is a different  mindset to invest in this.

that is why I want 1 share at worst 2 or 3 if I get a r9-r12 buyout.

 :)

Great minds must think alike.

Its a hedge bet that LTC will increase in worth.  The advantages of putting an investment towards something, in the worst case that, will only cover the 20-25% decrease in worth of the hardware itself seems like its worth the risk.

Trying to mine multiple coins based on profitability seems like a bad idea.  This will result having several small amounts of different currency.

Some of the multipools milk the most profitable altcoins and convert to btc for you. I make more than I would mining ltc. Just saying

Top end gpus are in short supply, so people like Sy say the diff won't go up too madly, like 4000 by Jan, and we'd still as y'all said have the rigs to sell once we'd mined a few 'ltc'.

I'm in two minds now

edit: link re the diff: https://litecointalk.org/index.php?topic=9192.msg66172#msg66172

This group buy doesn't seem like it's the same as the other rounds.  It looks like it is a 6 month mining contract.  Maybe I'm missing something, unless the coop votes to sell the equipment, there is no recouping the cost of the equipment.  A LTC miner can keep hashing much longer than 6 months and stay profitable.

Also, $300 a month for hosting is extremely expensive.  That is going to be a very large percentage of the earnings.  Hosting for the ASICs makes up only a small portion of earnings, that is why it's a great deal.  When hosting makes up more than 10% of the earnings, I say it's way to high.  As of today, running at 4 MH, it would take 6 days of mining to pay for the $300 a month hosting fee.  That is around 20% of the total earnings.

If LTC continues to rise in value, difficulty will also keep rising.  Buying in the hopes that LTC goes up will not work.

I will not be buying any shares this time.  Good luck to those who decide to buy.

7850 for $200 makes 400kh/s...

That's my thoughts as well...

I just got a 5850 on Craigslist for $60 and it's hashing at 330kh/s

But, with the group buy you don't have to factor in any time spent doing maintenence and the cost of electricity, riser cables, PSU cables, PSU/mobo/cpu/ram/etc (if you are out of PCIE slots), so I could easily see this being a good venture for someone who just wanted to get into Litecoins but didn't want to build a mining rig from scratch and doesn't have any PCIE slots lying idle.

You're asking for over $5300 for a 4kh machine?  Wow.

assuming high prices:
6x r9 280x @ 450/ea = $2700
Mobo, risers, cpu, ram = $350
1250w PSU x 2 = $600
3kw generator = $800
2000Va UPS (~30m+ uptime on a 2kw draw) = $800
Misc costs = $50

Total: $5300

I guess this makes sense...

3kw generator = $800
2000Va UPS (~30m+ uptime on a 2kw draw) = $800

they already have these items for the facility

Just pointing out the costs that would have to be associated to justify such a high cost per share.

Also... "Your share price includes acquisition of.... [USP and generator]"
This implies that they don't have that equipment yet, and besides, that equipment can't be shared if spec'd at the stated output.

Regardless, this seems to be very overpriced, but to each their own.

http://litecoinscout.com/static/speed34560-small-lin.png

i'm considering getting 3 shares but it seems like such a big risk. in a month the difficulty will probably at least double.
at that rate (diff 5000+), 500KHS will get you 0.6 LTC a week.
but as we see, at the current rate of craze for litecoin, the difficulty bounces up 3 times in 10 days... and the leaps seem to be getting bigger and bigger.

as of right now, for that same price (roughly 0.6B for 3 shares) i can buy 16.6 LTC.

not trying to knock anyone down or anything, but something really crazy has to happen to the litecoin price in order to ROI on this, and with the current difficulties BTC is having i really can't see that happening easy just like that.

i'll keep monitoring but no buying as of yet.

but a huge thanks for even considering this, love you guys!

1 share = $212 = 144-160 KH/s for 6 months


you can buy a used 5870 or 6950... for and get double that at least.....

Valid points:

- the 6 month date is to re-assess things, we'll just continue mining if it appears to continue to be profitable, or we'll sell the rig to help recoup costs.
- these rigs are rated for up to 2.4-3 Kilowatts, so there's a *lot* of power (and noise) involved with running a quad GPU miner. There's also fans, and A/C to consider.

Also: there is labor/testing built into the price. This is different from other GBs as we're building our own custom, high performance Scrypt rigs for us to use and need to include a fair price for professionally insured, custom built, high end Scrypt rigs.

This allows us to sidestep/hedge against hardware shortages in the ASIC world (near term Bitcoin hashrate is still in short supply) and expand ALT mining ops as needed.

** We will be doing multipool, even multi-coin mining. I listed this as an LTC GB but we will definitely be mining some of the better known ALT coins when it makes sense, as we're big fans of triangular arbitrage **

Yes, you could. A used card, that may or may have not been beat to sh!t and overclocked to near death (because the owner only cared about selling the hardware before it failed as all stressed components tend to do prematurely)...

...which also assumes that you have an entire rig you either paid for, or you bought a whole new rig for, and that you and your housemates don't mind the noise/heat/cooling & power costs.

I went into this issue further when the forums were down: http://www.reddit.com/r/dzminercoop/comments/1soze8/about_our_new_ltc_rigs_and_group_buys.

==

This GB is for those that want to get into LTC/ALT mining, but don't want to build a rig, buy a rig, or deal with the noise/heat/cooling/power costs of a GPU rig or farm.

Like you: I could easily build this rig myself (and deal with all the inevitable cuts and scrapes). This GB wasn't really meant for you or me. However, OTOH: my wife would def. not be ok, with a 2 or 4 GPU beast running in the house and driving up our electricity costs (about 50 cents a Kilowatt hour here).

We're actually building Facility #2 (we maxed out Facility #1), which needs its own gas generators and Server grade UPS units with battery banks, and additional A/C installation.

These are high end, custom built machines, assembled and tested in 'Murica. We're only going to sell and host/ship, the best of the rigs (and will hold sub-standard ones aside to address later). Our prices are very competitive with what you would get from a custom rig builder such as Puget Systems, except that we're more focuses on the mining side.

AFAIK: we're the only sales outlet that are offering custom built to order R9 LTC/Alt rigs at this time.

- One more thing: instead of closed cases, we may use open cases that can fit 2 mobos and up to 8 GPUs, if there's enough stock available.

There is a litecoin project you guys might actually be interested that's right up your alley. Jaisonlee from these  forums is involved they are ready to go live soon.
https://litecointalk.org/index.php?topic=2702.0

Cool! Thanks bitterdog. I'll check it out, as that's definitely up our alley. There's a number of companies attempting to bring ASICs and FPGAs to the Scrypt market; it's like Bitcoin ASICs Gen1 all over again, except with Scrypt. I'm keeping an eye on this space to see who has a shot of making it.

Who knows who will win and who will not even make it to market. All I know is that whoever launches real hardware will have ASIC or FPGA Scrypt hardware that we'll likely sell.

BTW: I've always appreciated your input and your objective, even handedness.

Cheers!

- One more thing: instead of closed cases, we may use open cases that can fit 2 mobos and up to 8 GPUs, if there's enough stock available.

Yeh do a knc, up the spec at the last minute.

I guess the thing is guys that building a 6 GPU litecoin rig with 280s costs something like $2600.  That's ~4500 hash rate.  Assume $5/day for power which is pretty accurate.  That's $150/month for power.  Cooling is a $10 box fan ;)  I get that there is overhead because of hosting fees, and I get that you want to make a profit.  But your rig cost is almost double what I would expect.  That's where I'm struggling.

I'm running 10 7970's and am making way more money of sexcoin than LTC. I just bought 4 more 290's. 280's are a way better deal if you can find them. Running rigs does make a lot of noise and heat but if you can handle that you will come ahead in the end over this GB and will have hardware you own that you can resell and you don't have to rely on anyone else or vote on when you sell what you do etc.

I think DZ has a lot going on and am wondering when they will start getting in over their heads if they aren't already.

I read all the numbers and I said I have to try to get my leftover btc rig mining ltc.  so after 34-40 hours of trying to make it work.  I am pulling 650khs with a hd7970 rig can add a second card  I HAVE A HD7790 I will pop it in and get the rig to 1k.  Now that it is cold in New Jersey running a pc pulling 300-450 watts helps to warm the house.  If it was not for this thread I never would have got the rig to run ltc. My Thanks  to dZcoop.   Making money for me in all kinds of ways.  next i need to figure the lit coin block chain wallet out as it is a bit different then the btc chain.   I am earning about .3 ltc a day with 650  kh running.

Good to hear that you doing well. I may build my own system to play with

yeah it is a real pain to find a cgminer + catalyst combo for your card.  they vary.

 I have cgminger 2.8.3 with catalyst 13.11 running the sapphire with windows 7 ultimate and an asus maximus gene.

    but if you put in another card it may or may not work.

You make it sound way harder than it is. I can build a rig from scratch in 2 hours including os load with steady hash rate no cuts, scrapes are any of the other FUD.

This makes no sense financially and if it's going to be hosted in a data center it should be using specialized GPU mining racks that can run more GPUs per motherboard/CPU.  You really need open racks and to use PCI-E riser ribbons if you want to build a GPU mining rig, using a desktop computer case makes no sense especially because heat is a huge issue with scrypt mining.  Also to be honest, scrypt mining is VERY finicky compared to SHA256 mining, you're talking about constant lockups and crashes if heat isn't perfectly controlled.  The amount of time that's going to go into keeping everything running is going to be much higher than with bitcoins and given how the Bitfury towers already caused a ton of problems I'm not sure the coop has enough manpower to keep racks of scrypt miners up and running.

Using what cards?  I find it is a pain in the ass sometimes trying to get different cards working together.  I had a 5830, 2x5850, and a 6950 in my rig and I had to try a lot of different versions of Catalyst and cgminer before they all wanted to work properly.

Then I tore that apart and am using 4x5850s and working on getting the parts for my other rig... put the 6950 in my sons computer so he can play stupid FFXIV

The new facility comes with me also having hired 6 more people to help out. I am currently training them right now.

I run 7970's right now and will be building my R9 290 rig as soon as the cards come. My 7970 rigs are all based on the same hardware from the mobo up so after I built the first the others were just imaged which is much quicker to setup.

I plan on water cooling everything on the R9 and making it my mining showpiece :D

Nice.  I bet it isn't hard getting the newer cards to work together, but mix-matching 58xx, 68xx, 69xx, 78xx, etc. seems to be problematic at times.  I like making rigs with all 5850s though.  They are really energy efficient, and I can usually find them for $60-80 on Craigslist... just gotta hunt for em.

I'm working on raising some funds to get in on this group buy.  I'm not tech savvy enough for my own setup, so this should be a good fit for me and I expect the LTC value to increase as cryptocurrencies become more well known to average joes like myself.

I stood up a 4x R9 280 rig yesterday.  Took about $1900 in parts and a couple hours work but I admit I have a pretty decent knowledge of PC building.  Without any real tweaks I'm hashing away at ~2800.  So less than $1 a hash.  You guys are asking basically double that plus the hosting and management fees and it's not coming online for a few weeks as the LTC difficulty really begins to soar over the next couple months.  I think that you will struggle to ROI on this.  Yes the hardware resale might ultimately push it into profitability but that's going to be a long road.  I am not saying they won't do a great job with managing this as they do a great job with all their GBs but it just might not make financial sense.

Why does everyone keep bringing up R9 280x's? Our supplier is out of these and we can't find a reliable source of them. These are being made with R9 290x's

Because the 280s are better from a cost/performance standpoint :)  Same reason everyone wanted 7950s.  Don't get me wrong the R290s are nice, they just are power hogs and you don't get the same ratio out of them.  The cost of building with 290s makes it harder to ROI because the increased hash they give doesn't outweigh the premium you pay for them.

The 280x's are better cards. They only get 100kh/s less and they are $100-200 cheaper. They also use less power and produce less noise/heat.

R9 280x is OOS everywhere I have checked

May I ask where did you purchased your R9 280x from? And what is your ROI estimate on this system?

Thanks

I bought them back on Black Friday when Newegg and others were blowing them out.  I actually have 3 more new in box sitting on the shelf that I bought for a friend who didn't want them so I will be selling them off.  ROI if LTC price holds reasonably steady should be 45-50 days.

Thank you very much, Let me know the price of those R9 280x if you plan of selling them.

in for 1 share, thanks :)

mine some protoshares!

The comments are right, the 280x is a much better choice than the 290x.

How many are you looking for? I have a decent supply of brand new Gigabtye R9 280x - GV-R928XOC-3GD REV2

Protoshares is still CPU only.

Ill take 1 share:

thx

Thanks and Welcome Aboard!

I've been away from the forums for a couple of days and I couldn't find this Round in the GB forum.

I see that this Group Buy has been banished to the winter netherlands of the all in one Alt. coin forum by the mods. You'd think that with all the money they made that the mods would further organize the alt coin subforums to make even more money. :D

Hey fellow alt.coin fans! Why do I feel like I was sent to the Island of Misfit Toys?  :D

Don't they know that all that glitters is not Bitcoin?

It's much better from a khash per watt perspective to build a mining rig using 280x's as well as from a $ per khash perspective.  Which is not so coincidentally why all the suppliers are out.  It's also worth considering trying to acquire 7970 or 7950 cards as the 7970 and 280x are actually the same chip and the 7950 is a close second in mining favorability.  I think a GPU mining rig could be a good idea but again this setup you guys have proposed is just not the right way to go about it, I know the 280x's are impossible to obtain right now but really I would be patient about this, with all the crypto currency prices tanking these cards will be much easier to obtain soon and in the meantime you can do more planning on how to build a serious crypt mining rig.

If you want some suggestions on how to design a high end scrypt miner I'm sure we'd be more than happy to help with the build. 

any update on this? so many questions asked and other suggestions given. still on track?

have to say I was inspired by this r 20x to try once again to do LTC.  I now have 3 rigs and I don't know what you have done but this card is pretty good.

Hey you should make a dzmc coin for us to mine

Is this round hashing?

i think it is being shutdown

is this still open? i would like to reserve a share

What are the status on the LTC rigs? Was the round canceled or is it hashing by now?

Full btc refund received with thanks.

Yes, we had to cancel the rigs (and a few rig orders).

Sorry, we didn't receive a couple key critical components in time and instead of dragging out the drama, we just did refunds.

No problem (good decision, even though scrypt is not as sensitive to time-to-market as bitcoin), I was close to getting into R20x, but I decided to upgrade my old rig instead, since the R9 290X is too expensive in terms of hash/$ (imo). I went with the R9 280X, they had ROI in about a month.

I will definitely consider if you open a new scrypt round.

I would be interested in a GB if you  started  one for the KNC Titan or the Fibonacci Epsilon.
