I've been out of the BTC market for a bit simply because I don't feel that the prices are justified, but I hopped on over to bitcoincharts today and I had deja-vu from almost 2 years ago 






Just like then, the forum is full of people predicting endless future price increases with no possible downside.
Just like then, price has doubled in less than 2 weeks.

Best of luck everyone 

So I have one of these for sale:



Will come with the box, cables, software and serial keys (not sure if I have the discs for the software but I have the exes and required serial keys).

This also comes with a copy of NI's MASSIVE synth for Maschine.

Looking to get some offers to see if anyone here can do a better price than I can get locally. Will post up pictures shortly but this thing's basically mint, has been used on stage all of once and most of the rest of the time it's been sat in the studio.

Looking to buy 13 BTC for UK bank transfer (will be coming from RBS, so if your bank supports faster payments it'd be same day).

Please pm with offers - users without significant rep will need escrow.

Cheers

So, as the title says, I'll buy anything that can be bought online in the UK and ship it to you anywhere in the world for BTC.

My terms are basically: 24 hr average + 7.5%, less for large orders, escrow completely fine so long as we can agree on someone trustworthy, and customs charges are yours to pay.

If anyone's interested, pm me with what you're looking to buy and where you want it sent, and I'll get back to you with a £/$/BTC quote.
I'd prefer to start relatively small, so if we've not done business before I'd rather not be ordering you a rolex  

I can give references from people who used to mine for my little hopping proxy, as well as a few deals I've done on here in the past.

Haven't been active on the forums for a few weeks - last I checked BFL had moved their shipping date from October-November.
I guess it's now December? Yet still no functioning prototype has been demonstrated...

I'll check back in a few weeks when everyone's complaining about BFL shifting their shipping date to January  

Edit: Seriously though, there's honestly been nothing shown of any great substance yet for a product that was supposed to have shipped weeks ago? Why am I not surprised?

So, do you think BFL will hit their oddly rounded target of 1Gh/s per watt?
We've heard a lot of power estimates from other ASIC manufacturers that are mostly in the range of 200-500Mh/J, with BFL claiming 1000Mh/J, do you think they'll hit this, or is it all likely to turn out incorrect like the early "1000Mh/s @ 20W" estimates from the original BFL single?

Just curious to find out what the community thinks - personally I don't take issue with the idea that BFL will come out with the most power efficient product (they've had more money to throw at the problem than anyone else for starters) but given that the last lot of estimates they made from simulations gave a claimed efficiency of five times what was achieved with the final product I'm somewhat skeptical. Will be interested to see what happens with the BTCFPGA products - supposedly molex powered, implying a limit of ~110W @ 54Gh/s unless they're using multiple plugs, so if BFL can produce a product slightly more efficient they may well hit their numbers.
I've also made up a quick bet if anyone wants to put their money where their mouth is over this:

I have a few ATI 7970s to sell, parting out some of my rigs since it seems there'll be little point in mining with them soon.
These still make fantastic gaming cards, so I've sold a few locally for cash. If I can sell some for BTC that'd be a lot easier for me.

I've found that I can get anywhere from £225-£250 per card after fees and such listing them on ebay/gumtree, so I'd be looking for offers in that sort of range (BTC equivalent ideally).

Cards are all reference designs, they've run undervolted rather than overclocked their whole lives as that worked out more profitable with my power rates. The ones I have left now were mostly picked up in may/june, and as such should be easy enough to RMA for quite a while. Happy to do escrow using someone suitable 

As of right now:

50BTC: 3826Gh/s
Deepbit: 3316Gh/s

I know deepbit's hashrate has been down a bit due to attacks and the like, but have they finally been overtaken?

I'm looking to buy some hashes from GPU miners - paying 0.0000185 per share for the rest of this difficulty period. Pm me if you're interested.

Edit: New difficulty period, unfortunately higher difficulty, 0.00001727 per share is the new rate.

So, I'm looking to buy some hashrate, currently paying 0.0000183/Share.
If you're reputable we can agree a number of shares and I'll pay in advance, otherwise I'll pay daily.
Message me if interested 

So, I've been wanting to pick up one of these cameras for a while, ideally the HD versions but I'll consider anything. Make me an offer inclusive of shipping to the UK 

Here's one for the rig builders - really wish I'd been able to get one a year ago 

http://www.scan.co.uk/products/1500w-evga-supernova-120-pg-1500-xr-90-eff-80-plus-gold-sli-crossfire-eps-12v-fan-atx

Does 1650W on 230VAC - enough to run a 7x7970 rig with a bit of undervolting 

So, difficulty's about to retarget to somewhere in the range of 2.7 million (personally I blame mini-rigs), which will make each share worth ~18.52µBTC. I'm looking to pick up some more hashrate and I'm willing to pay at least 19.5µBTC/share.
Hopefully this will help some people put off selling their GPUs for another fortnight 
PM me if interested.

So, I've been considering offering small loans on here - thought it might be interesting when offering loans to miners to make them repayable by mining  

An example would be:
-Assuming the next difficulty change is to 2.5 million (gives a nice 0.00002 BTC/share at 100%).

User A requests a loan of 10BTC, I grant it, and in return they have to mine at least 526316 shares (10BTC @ 95% PPS) during the next difficulty period to the pool details I specify in advance.
If they overshoot the target, I pay them 0.0000195/share (97.5% PPS) for any shares mined over and above 526316. If they undershoot the target then we negotiate new terms - payback of some of the loan in BTC or further mining following the difficulty retarget.

Would any miners be interested in accessing loans in this way?

Reading through the forums, I thought it might be quite fun to see how BS&T investors go through the five stages of loss...

First we have denial:

Anger:

Bargaining:

Depression and Acceptance coming soon! 

So, a lot of big news the past couple of days, with BS&T closing and people waiting to see whether pirate will pay back depositors or if it's a ponzi as many on the forums had speculated.

What I want to ask is - could Pirate already have cashed out his remaining BTC (being responsible for the crash)?

He'd then have an entire week to move the funds (and himself) somewhere safe, before people realised that they weren't going to see their BTC again.

I've been pondering this question over the past few days, trying to work out what the total level of exposure to Pirate's scheme is on these forums. Obviously we have information like the fact that he apparently paid out 26000BTC in interest this week, but we don't know either the average rate (although presumably much is in passthroughs at 7%) or the amount of accounts that are set to automatically compound rather than pay out interest weekly.

Obviously in analysing the prospect of an imminent default, it would be good to know what level of liability you're looking at, and I'm personally quite concerned over how exposed the market has got.

So, it seems that the majority of BTCST deposits are in passthroughs (although it's difficult to know, given that there's so much smoke and mirrors surrounding total levels of deposits and the like).

So, looking at some of the pass-through programs we can try to work out how much is being invested:

BitcoinMax - in the region of BTC110000 (based on interest payments) https://bitcointalk.org/index.php?topic=83904.0
BurtW's PPT bonds - about BTC18000 most of the time based on compounding interest over 4 weeks https://bitcointalk.org/index.php?topic=76594.0
INAU - Unknown amounts, targeting large BTC amounts, he presumably has tier-1 trust account status so at least BTC25000 in that account https://bitcointalk.org/index.php?topic=91375.0
Hashking - Unknown total, also a tier 1 account so > BTC25000. He has 8000BTC of principal in deposits to his 50% insured pirate bonds. The amount uninsured bonds is unknown. https://bitcointalk.org/index.php?topic=66802.0
Brendio - Tier 2 account, so between BTC15000 and BTC25000. Claims to be near the top end of that. https://bitcointalk.org/index.php?topic=82772.0
notme - Previously had about 2000BTC in his PPT, not sure if the current spreadsheets are accurate but if so he's down at 144BTC now having lost out on trust account status. https://bitcointalk.org/index.php?topic=60405.0
OgNasty - Provides data! BTC720.36 https://bitcointalk.org/index.php?topic=75843.0
ShadowAlexey - BTC2155 https://bitcointalk.org/index.php?topic=75738.0
TyGrr-P - Goat's bonds, BTC30000 https://glbse.com/asset/view/TYGRR.BOND-P
BitFoo - Another GLBSE bond, BTC4674 issued, https://glbse.com/asset/view/FOO.PPPPT

Also, known deposits from forum members direct:
Patrick Harnett - apparently about BTC10000, although his own program does not hold BTCST assets https://bitcointalk.org/index.php?topic=61262.0

Working on the low-end estimates for certain trust accounts (and totally ignoring undisclosed exposure from other members) that gives exposure of BTC240,693.36 or $2.56 million at the most recent MtGox price.

Obviously some of these numbers are rough estimates, and I have no idea how much over and above this is held by some lenders that don't disclose totals (PPT ops - I'd love it if you could shed some light on your level of exposure for the sake of having accurate data in the community). In addition, asides Patrick, I'm not aware of anyone disclosing even an estimate of the amount they hold in a private BTCST account (again, if you have one and want to contribute please do).

I've been thinking about where mining's headed with the (potential) release of BFL ASICs and such.

There's one factor that I don't think has really been discussed: Namely, when will BFL ask for their FPGAs back for trade-ins?
They could potentially be taking back a substantial number of singles and mini-rigs, so if this precedes the full ASIC release, is it not possible that this could knock several percent off the difficulty whilst we wait for their ASICs to hit the market?

So, decided to try pointing one of my rigs at LTC mining:



Obviously, something is not going entirely to plan.

These are my settings in reaper:

Code:

host 127.0.0.1
port 9332
user username
pass password

protocol litecoin

worksize 256
aggression 18
threads_per_gpu 1
sharethreads 18
lookup_gap 2
gpu_thread_concurrency 6144

This is my litecoin.conf from the roaming folder:

Code:

rpcuser=username
rpcpassword=password
rpcallowip=127.0.0.1
rpcallowip=192.168.x.x
rpcport=9332
daemon=1
server=1
gen=0

block_nTime=1317972665
block_nNonce=2084524493

Whoever can fix this for me will get some LTC from me when I start mining successfully 

I have a bunch of these pumps to sell, they're OEM so come without boxes but are unused.

Looking for 9BTC each or 16BTC for 2 shipped to UK, international shipping will be more so pm and I'll find out  

Happy to use any respectable escrow service.

Pictures will be coming later once I've got my SD card reader handy.
