2081  Bitcoin / Hardware / Re: Black Arrow 28nm 100Ghash Bitcoin ASIC from $1.99/GH/s, miners from $2.97/GH/s on: April 25, 2014, 05:07:14 PM
3.We are keeping our promise to price match per Ghash any genuine new miner in stock at the time of shipment and if needed we will dispatch more hashing power.
Note: Not all our competitors supply PSUs and Touch Screen LCDs, therefore if we compare our miners with these we will subtract the price of our extra hardware before the price match.

Excellent. Bitmain is already shipping miners at $1.5/ghps. So if someone paid $6k for Prosperos, they should be getting at least 4 TH/s right now. In a month when you actually do ship, we're talking more like 5 TH/s. Looking forward to seeing you match the competitors.
2082  Bitcoin / Hardware / Re: [ANN] Spondoolies-Tech launches a new line of ASIC miners - Best W/GH/s ratio on: April 25, 2014, 04:54:00 PM
For bulk SP10 customers, we can do an intro with the owner of a WA DC with the following costs:
160$ / SP10 / month (minimum 6 months, one month deposit) + one time 100$ setup fess (includes the cables and mounting ears)

At 1.25 kw that comes out to $.18/kwh. That's still quite costly.

Why do you claim to accept credit cards, when you do not actually accept them?
2084  Economy / Service Discussion / Re: PBmining - legit? on: April 24, 2014, 09:20:30 PM
I'm also using them. At the moment i have 20GH/s and It's mining really fine, i'll see how the pay out will go this weekend. The price looks really low so If everything goes good might buy more hash in the  future. Though It's only plans..

Excellent choice. The more you pay them, the longer they will can keep this ponzi running.
2085  Bitcoin / Hardware / Re: [Antminer S1 Sales open] Price changes daily, now 0.63 BTC for 180GH/s on: April 24, 2014, 07:42:32 PM

Not quite. You should include the cost of a power supply. And since April is nearly over, you don't get a full month at the low difficulty in your calculation. Look at this:

https://tradeblock.com/mining/a/379dc97925

Although tradeblock is too pessimistic on difficulty increases a few months out. So yes, a new S1 might break even.

  • BFL stole nothing. Unless someone can provide some proof to the contrary, they are lying.

BFL mines with customer hardware on the mining pool they secretly own (EclipseMC). That is stealing.

I am not sure why AMT_miners comes and post here, and does not answer my question which I asked very politely.

Because by not answering, they can string you along for longer. AMT_Josh learned from the best (BFL_Josh) in how to string people along month, after month, after month. With luck your issue will be resolved by the end of the year.

Note that the percent changes (not increases) from year to year were

 2011 -> 2012  300%
 2012 -> 2013 3024%
 2013 -> 2015  314%

Neither constant, not uniformly increasing.

What will be the percent change 2014 -> 2015?

The simplest formula that will fit the three data points above is a parabola. Working in log scale, this is what I get:

Horrible chart, because you ignored valid data. You can't just ignore previous years.
2089  Economy / Speculation / Re: 200k Gox Coins in the Pipeline on: April 24, 2014, 02:55:53 PM
Do you have any idea the effect this will be having on the volatility of Bitcoin?

Very little. Daily trading volume averages around 20k on slow days, peaking at well over 300k on busy days. Dumping gox coins all in one day wouldn't be all that unusual of a trading day. The liquidator is not going to place a 200k market order on some random exchange. They will be liquidated in an orderly manner. The effect on the market will be minimal, and temporary.
2090  Bitcoin / Bitcoin Discussion / Re: Has anyone ever cancelled a BTC transaction after 1 confirmation? on: April 24, 2014, 02:39:00 AM
Any time a block is orphaned, there is a (very small) chance a transaction from the orphaned block won't get confirmed in the new chain. Typically there are about 2 orphans per day:

https://blockchain.info/charts/n-orphaned-blocks?timespan=30days&showDataPoints=false&daysAverageString=1&show_header=true&scale=0&address=

A single confirmation is by no means a guarantee that the transaction will stay valid. That is why the normal bitcoin client shows transactions as "unconfirmed" until there are 6 confirmations.

2092  Alternate cryptocurrencies / Mining (Altcoins) / Re: Swedish ASIC miner company kncminer.com on: April 24, 2014, 01:24:03 AM
This has already been discussed numerous times: only Bitfury used the proper design flow for the mining chip: BSIM (or equivalent analog/mixed-signal) simulation, but this was his first ASIC project.

I would so love to see him do a 28nm shrink.
2093  Bitcoin / Mining speculation / Re: The Best Mining Rigs Are Now Barely Profitable -- Now What? on: April 23, 2014, 11:53:13 PM
Mining is pretty well over folks...most people just don't realize it yet.

That's what people said 3 years ago:

Hi fellow miners,

I bought a HD 5970 recently and was waiting for this weekend to get the rest of the hardware needed to complete a mining platform. However with the increase of 37% difficulty recently, I am hesitant now if I should continue with the project. ... Based on using the online bitcoin calculator. I will hit negative income on the 5/12/11. Will that be accurate?

The big unknown - the exchange rate. If the exchange rate goes back up again, miners will continue to be profitable. If it keeps dropping, then yeah, miners are going to start shutting down their machines.

Sorry but Dorian did create BTC. He is suing every solvent BTC exchange for treble damages. If Mt. Gox doesn't flush you, Dorian will. Actually, Dorian is too late. True story.

Are you high or drunk, or both?
2095  Bitcoin / Mining speculation / Re: If I get free electricity... on: April 23, 2014, 09:56:46 PM
price per gh/s would be the Yellowjacket USB devices. I got one for $40AU and it gets 2.6gh/s all day long. run them up in a line and cool them and you have some very low cost/mh/s rig.

That's a horrible price! 10x of those gets you 26 GH/s for $400. 1x Antminer S1 gets you 180 GH/s for about the same price. 26 GH/s vs 180 GH/s.
2096  Bitcoin / Hardware / Re: New Official AMT Thread on: April 23, 2014, 07:32:24 PM
IF I had to take a wild guess here, I would say they are looking to fulfill all the orders left, get the miners to people and I presume get working miners to those with failed ones and then close up shop. I might explain why they are "sold out".

Except for the fact that they are still accepting orders for 2.4T and 3.2T units.
2097  Bitcoin / Hardware / Re: AntMiner S2 1TH/s Miner (1w/GH/s) on: April 23, 2014, 04:14:13 PM
+ 1, but if you have only BTC and you want to have more BTC ?

Then send your BTC to me. Every day I'll send you a few satoshis. In a few months, you may or may not receive more BTC than you originally had.
2098  Bitcoin / Hardware / Re: AntMiner S2 1TH/s Miner (1w/GH/s) on: April 23, 2014, 03:39:31 PM
ROI is possible if BTC reach USD 850 and above.

So just buy BTC. Then when BTC reaches 850, you'll be at +75% ROI, rather than simply break even.

It was more like batch 2.5 Batch 3 isn't released quite yet. I'm sure Bitmain is in the zone building machines like crazy so they can immediately ship Batch 3

I hope they do something about the case design. They can't keep shipping them with little plastic holders.
