1  Alternate cryptocurrencies / Marketplace (Altcoins) / [want to dump] Super Bitcoin on: January 04, 2018, 01:30:29 AM
Hey folks,

I have roughly 2.5 super bitcoin that I don't want or need. I can't trade it on any exchanges that I'm registered on, and to be honest I'm too stubborn to register for one that does.

Right now this coin is going for 175 at coinmarketcap. Since it's probably going to be a pain for anyone to sell, I'll exchange it for BTC (although I won't refuse offers of other alts) at 149USD/ea 125USD/ea. Any offer is welcome, if there's zero interest I'm willing to go lower. Willing to do ognasty escrow--I can put up collateral if you pay the escrow fee--or you can deal with me directly. If you don't want to use escrow you must send first. I have a long trading history with far more valuable items than this, although I've been very quiet for the past few months. It's up to you

Anyone have one of these lying around? I'll give ya $50 usd for it and pay for shipping. I'm located in Canada.
3  Economy / Computer hardware / [Sold][In Hand] Antminer L3+ on: June 29, 2017, 02:35:25 AM
This is going to sound ridiculous, but I'm asking $5000USD in btc for it shipped within Canada/CONUS.

On ebay it's going for even more stupid amounts of money. I know y'all hate ebay... but maybe I can get a stupid amount of money too. I bought this recently and although I'd like to mine with it, I doubt it will make more than $5000USD in its lifetime, so if someone wants to pay me that I'll gladly take their money.

Another 250USD and I'll throw in the PSU. I bought it brand new from newegg last week. It's an HX1000i, 80 plus platinum, runs at 90% efficiency with this load on 120v. The psu only comes with 8 pcie outputs, but I used a molex->pcie to power the controller and the L3+ runs fine. Hashes stable at 550MH/s @ 910W clocked to 425. If you run it @ 220v you'll probably get even better efficiency, but who gives a shit about efficiency with this money printing monster. You might be able to squeeze more coins out of it with more aggressive overclocking--I haven't tried because I'm a wuss.

Willing to do ognasty escrow, you pay the fee. If you're a silly goose, you can also pay me up front.

If people are actually interested at this price, I'll post pics.

If not... well... I tried.
4  Bitcoin / Bitcoin Wallet for Android / Unable to recover bb10/android wallet backup on: January 01, 2017, 10:13:38 PM
Heya folks. I have some magic internet money that I stored in the bitcoin wallet for Blackberry 10. This is the same wallet as the android one, although the versioning seems to work differently.

I made a backup in October of my wallet, and recently my phone went kablooie. However, I am unable to recover the bitcoins from my backup file. When I put the backup file in the Download folder in an android phone (I ensured this was the correct folder), the android app did not see the backup. Same with a blackberry phone running the latest bitcoin wallet.

Manual decryption is giving me no dice either. When I run the following command:
Code:
openssl enc -d -p -aes-256-cbc -a -in -bitcoin-wallet-backup-2016-10-24 -pass:MYPASSWORDHERE > bitcoin-wallet-decrypted-backup
I get the following output:
Code:
error reading input file

Perhaps the backup file is corrupted? The size is 33,697 bytes. Any help would be greatly appreciated, folks!
5  Economy / Computer hardware / [SOLD] 3x IBM 2880w PSU Packages on: December 09, 2016, 02:18:10 AM
I'm getting out of mining for the foreseeable future, so I've got some PSUs to dump on y'all.

I purchased these Double A packages from Finksy a few months ago. Here's what you get with each package:
1x IBM 2880W PSU
1x IBM 2880W Breakout board
20x 24" PCIe 16awg cables
1x 14awg C19-C20 cable

They're located at Allinvain's Cryptoboreas hosting service in Labrador.

$150USD/package + shipping. Buy them all and you can get em for a bit cheaper than that.
6  Economy / Computer hardware / [WTS] 11x Antminer S7, B18 with 2 fans on: October 23, 2016, 05:09:39 PM
These are SOLD!

I'm asking $265 USD for each S7, hosted at CryptoBoreas in Labrador, Canada.
My hosting term for these miners expires on November 3rd, so any sale would be effective on that date.

I also have PSUs available if you don't have any to power these bad boys. I bought 6 "Double A (Antminer/Avalon)" Packages from finksy a while back, he asks for $190/package, and I'll let them go for $170 USD.

This price does not include shipping. As for escrow, OgNasty is my favourite.
7  Economy / Computer hardware / [WTS] Desktop PC for Storj/SIA on: June 08, 2016, 02:56:49 AM
Heya there folks. I built a desktop PC a while back for mining storj/sia/whatever, but for some reason I've totally lost interest. I figured since there's a rally on these alts there might be some interest from you folks.

It's got:
  • An intel quad Q series processor (I forgot which one)
  • Enermax EPR625AWT PRO82+ 650W
  • 6gb of DDR2 RAM
  • 9TB of rated storage spread over 5 1TB drives and 1 4TB drive.

The mobo supports 6 sata devices and everything fits comfortably in the case, so it's not a monstrous frankenstein rig or anything.

I measured it with a kill-a-watt and it draws between 100-150w @ the wall depending on CPU load with all drives spinning. If anyone has serious interest in this I can take some pics. It's probably gonna be killer to ship, so local pickup (Ottawa, Canada) is preferred!

Anyways, shoot me some offers. Lowballers will be drawn and quartered.

This is kinda relevant to the computer hardware board. Kinda.

I've always had a soft spot for BFL, and I never managed to get my hands on a mug!

I'm offering 20USD + I'll pay shipping to Canada.
9  Economy / Computer hardware / [WTS] Risers [Canada] on: April 01, 2016, 03:00:33 PM
I've got a friend that wants to offload a ton of risers he bought a while back.


  • 3.50 USD for an unpowered riser. (8x)
  • 4.50 USD for a powered x1-x16 riser. (6x left)
  • 5.50 USD for a powered x16-x16 riser.

Discounts for people buying multiple units.

Ships from Ottawa, Ontario. Willing to do local pickup, otherwise you pay shipping!

I'm locking it so it stays that way.  Wink

11  Economy / Computer hardware / [WTB] FutureBit MoonLander on: January 21, 2016, 07:52:22 PM
I missed the group buy, and they look so good.

I'd like to pick one up for the original $32 USD price + shipping to Canada.
Let me know if you have one.
12  Economy / Computer hardware / Does anyone sell step downs / 9v PSUs for antminer s5s? on: January 16, 2016, 11:40:53 PM
I'm thinking about picking a few up, and I remember that they can only get really good efficiency when hooked up to a lower voltage power source.
Does anyone sell conversion kits (that accept 12v and put out 9v with minimal efficiency loss) or special PSUs for these miners?

Thanks everyone, and have a fun-tastic weekend.

16  Bitcoin / Group buys / [CLOSED] [Group Buy + Group Hosting] 3.5TH/s Avalon6 + Platinum PSUs! on: November 12, 2015, 02:26:15 PM
We didn't hit the MOQ!

UNITS RESERVED: 4
Reservations close Sunday at noon EST (5:00PM UTC)

The Avalon6 is rated at 3.5TH/s, 0.29 J/GH @ the wall (1015W). BlockC has informed me that Avalon should be releasing a firmware update in 5 weeks that will get it up to 3.65TH/s at the same efficiency. Detailed specs: http://www.blockc.co/products/avalon-6-3-5-th-s-bitcoin-mining-server

What is this?
This is a group buy for the Avalon6 miner + 3 months rental of Finksy's platinum rated PSUs + 3 months (renewable) hosting @ Great North Data up in Labrador, Canada.
At the end of the hosting period you have the choice to ship the miners out or to renew the contract. Those who choose to renew may get a discount on PSUs with Finksy, and GND will be lowering their rates across the board in several months.

The advantages of going with this group buy are numerous: We'll get a solid volume discount on the Avalon6 units and PSUs, the MOQ for individuals in this buy is 1 instead of 10, our hosting is cheaper than going alone, and we save quite a bit on shipping. Already we have a better rate than the official blockC website as it is. All in all, not too shabby!

This is the original discussion thread (now outdated) where this plan was hashed out:  Roll Eyes
https://bitcointalk.org/index.php?topic=1171705.msg12952744#msg12952744

COSTS:
15 units:
$1320 for the Avalon6 (could go lower)
$50 for shipping
$66 for import duties on the Avalon6
$30 for 3 months of PSU rental
$144.06 for 3 months hosting @ 47.31 USD/KW/Month

50 units:
$1310 for the Avalon6 (conservative estimate, could go lower)
$20 for shipping
$65.50 for import duties
$30 for 3 months of PSU rental
$137.64 for 3 months hosting @ 45.04 USD/KW/Month

100 units:
$1300 for the Avalon6 (conservative estimate, could go lower)
$10 for shipping
$65 for import duties
$30 for 3 months of PSU rental
$133.05 for 3 months hosting @ 43.55 USD/KW/Month

Note that the final costs for the Avalon6 and shipping will be determined after they have been reserved, these are estimates provided by blockC. If the total price has increased you can withdraw without penalty. The numbers here serve as a guide but won't be exact.

TIME FRAME:
The Avalon6 units will arrive at blockC on November 20th. From there I've been told it will take a week to arrive in labrador. It's possible the batch sells out before we raise all the funds. This isn't a disaster, blockC has confirmed they will be receiving more batches in the future.

Finksy will need payment earlier, as he needs to pay his suppliers before sending us units. We'll need to pay him by monday night, which is why the reservations close on sunday. You guys will have to make the payment to the address Finksy provides by Monday at 11:59PM EST (4:59AM UTC Tuesday), or you risk losing your deposit!

PAYMENT:
  • There is a refundable deposit of 0.06BTC/unit to ensure you are actually serious. You will receive that back once the group buy is over, provided you haven't skipped a payment or backed out. Reservations will close in a few days, I will give 24hrs notice before that happens!
  • BlockC and Finksy will provide me with a payment address after reservations are closed, you must send me a signed message from the sending address containing your username.
  • Great North Data will provide me with a payment address when the miners arrive in Labrador. If you don't pay for hosting, your miners will be redirected to mine for GND in order to pay for it, and then returned to you!

WITHDRAWL:
You may back out of the buy before we pay BlockC, but you lose your deposit! After that, it's too late.

TRANSFER:
You can transfer the ownership of the miner to another person while the hosting contract is underway (it's only a pool switch and a spreadsheet update on my end), but that person can't move their hardware until the term expires.

WARRANTY:
From the blockC website:
Quote
WARRANTY:
Avalon miners include a 90 day warranty, starting from the date goods are received.
This warranty is serviced by BlockC.co in California.
We promise to replace or repair faulty miners, but lost mining earnings will not be compensated. Buyers pay inbound shipping and we will pay the return shipping.
Note: miner modification or disassembly will void warranty. See complete Warranty for all warranty terms.
The group buy itself doesn't provide a warranty, which means you're on the hook for shipping costs to blockC if your miner fries.

HOSTING DETAILS:
Detailed power cost (converted from CAD to USD, rounded):
  • 6.61/KWH (10 Units)
  • 6.30/KWH (50 Units)
  • 6.09/KWH (100 Units)
This includes sales tax and a 24/7 onsite tech. These are awesome rates.

I will sign the hosting contract and serve as the representative of the group buy to Great North Data. This is so they don't have to deal with many different customers for the same set of hardware. Please contact me, not great north data, if you need to switch pools or otherwise have problems.


This is the payment address for reserving units (send 0.06BTC for each miner/hosting/psu package you are getting):
(GB closed)

Send from an address you are capable of signing messages from. Please PM me a signed message from that address containing your username.

17  Economy / Computer hardware / [WTB][US/CA] GPU on: October 21, 2015, 03:42:16 PM
Hey everyone, I'm located in Canada and I'm looking to buy a single GPU for a midrange gaming rig I'm building for a friend. I'm interested in anything of equal or greater speed than a 7970.
I can do escrow with OG (you pay the fee) or you can ship it upfront to me: see trading history. If you aren't in Canada or the States, shipping will probably kill this deal.

It needs to be in working condition and not have any artifacts.

Let me know what you have and I'll make you an offer!
18  Economy / Computer hardware / Broken Steelseries Siberia V2 on: September 10, 2015, 06:07:43 PM
It's more of a computer peripheral, but I figured since USB hubs are fair game this is too.

It has two jacks at the end of the cable, one for the mic and one for audio. The audio jack broke a while back, I cut it off and soldered on a new jack. It was pretty hard to do, the actual copper wire is very, very thin. A month later it the audio stopped working again, and I figured it wasn't worth the effort to fix! The microphone still works--it sounds pretty good! Other than that, the headband is worn.

I'm planning on throwing it out. If you want to fix it up and use it (gamer on a budget), then I'll ship it to you for practically nothing. Say $3USD + actual cost of shipping. I'm located in Ontario, Canada.

I'll give this a few days then I'll lock the thread and chuck the headset!
19  Bitcoin / Group buys / [Proposal] Mining Co-Op on: September 05, 2015, 07:06:27 PM
Thread is out of date.

Most hosting companies give pretty big discounts for bulk buyers, and you can get small bulk discounts from most hardware manufacturers. Why don't we take advantage of that in a simple, transparent way?

Updated game plan as of 2015.09.25:
  • Pool funds in a 4 of 6 multisig address with keys held by trusted members of the community.
  • Negotiate a purchase of hardware.
  • Buy the hardware and pay the hoster up front for a lengthy contract (6 months to a year).
  • Have the hardware shipped directly from the manufacturer to our hoster.
  • Mine at Kano's CKPool, enable reward splitting between addresses. Payouts go directly to participants--there's little risk here.
  • At the end of the term we can sell the hardware or renew the contract.

If we follow this plan step-by-step we only have to trust three entities: The manufacturer, the hoster, and a 4/6 vote of the "committee". After the miners have been deployed, we only have to trust the hoster (and they tend to be the most trustworthy of the three).
Feel free to discuss this below!

UPDATE: I've talked to a hoster that's given me a fee schedule as long as I keep their name a secret until we start the buy. I've dealt with them before, and you will know who they are before this kicks off, if this ever gets off the ground.
50KW @ $58/KW ($0.08/KWh)
100KW @ $55/KW ($0.076/KWh)

I've also been told by a hoster that if we can get a huge amount of hashrate, our rates can get as low as $45/KW--but that's only going to be an option in a few months. It seems like the SP50 is only going to be selling around then anyways, so the best time to buy is when that miner starts selling to the public.

Feel free to discuss this below!
20  Economy / Computer hardware / [WTS] Mini Farm on: August 08, 2015, 12:22:20 AM
A sale of all hardware is currently pending, I will update with more info as this progresses.

Hey guys, I'm selling off a bunch of my mining hardware.

Total hashrate 7.5TH/s, give or take. Here's real world stats from my pool page:
http://eligius.st/~wizkid057/newstats/userstats.php/1Le1LamYdsWVgL5VcTuRyvDxAzsf5NocSi

Parts list:
  • SP30 with a broken loop (currently hashing at 4.05TH/s)
  • 6 antminer S3+s
  • 2 antminer S3s
  • 3 EVGA 1300W PSUs

Hosting for all the miners is paid through september 30th for the sp30 and October 2nd fot the s3s. They are currently hosted at great north data @ $0.08333/kwh. They ship out of Goose Bay, Labrador, Canada, or you can opt to just continue the hosting contract after that point. The colo has a $25 handling fee for each miner.

I can't provide pics. The SP30 is dented on the front grill and doesn't like rapidly switching pools, but works fine (as you can see from pool stats). The S3s are in good condition. I figure the pool page, my trading rep, and my willingness to use escrow is proof enough that this hardware is real.

I would prefer to sell them to at most one or two buyers. Ognasty escrow or payment up front preferred.
Asking 2200 USD eqv in btc. This does not include shipping as you may prefer to just extend the current contract. Remember that around 55 days of hosting are included.

Feel free to discuss this below.
