Bitcoin Forum

Hi folks,

there are lots of sites out there listing mining ASICs, often with wrong/outdated data and it is hard so find out what is actually available.
This is what I've found:

Name                         Price         GH/s  $/GH/s  Notes
5 GH/s Bitcoin Miner    $274           5   18,25      BitForce 5 GH/s SC          Butterfly
25 GH/s Bitcoin Miner   $1249   25   20,02      BitForce 25 GH/s SC          Butterfly
50 GH/s Bitcoin Miner   $2499   50   20,01      BitForce 50 GH/s Miner       Butterfly   
500 GH/s Bitcoin Miner   $22484   500   22,24      BitForce 500 GH/s Mini Rig SC    Butterfly      
Avalon #1                   $1299   65   50,04            
Avalon #2                   75 BTC   65   8,67      Orders Opened On: Feb 2nd, 2013    65 Gh/s    620w@120v AC
Avalon #3                   75 BTC   65   8,67      Orders Opened On: March 25th, 2013       

I have found only Butterfly and Avalon. Are there other Companies already delivering?
It seems that Avalon is getting more and more expensive although GH/s stays the same??? Their website is somewhat unclear, can I still order Batch #1???

  Avalon doesnt sell miners now on and BFL is slow shipping out miners.  you can try Bitfury or KNC.

Nothing on that list is available currently. Avalon batches are sold out, BFL delivery takes... a year.
Look a table at https://bitcointalk.org/index.php?topic=209750.0

The table says, butterfly will deliver in september.

 ;D

Table states what BFL says: in two months, or more.
But BFL repeats that for a year now. Their June 2012(!) orders started shipping last month.

They said the same thing last year. September 2015 is more likely.

If you want Avalon B2 or Batch3 you can pretty much get them at cost today and pretty much today only.

Scads of B3 folks are putting in refund requests, but might be willing to sell at cost (or if their refund doesn't go through before Bitsyncom ships).

If you have 75 to 100 BTC and want to mine this week with an ASIC... today/tomorrow could be your day.

u can only buy USB miners atm, from resellers, thats all it is right now

Or you can buy this guy :D

Why are people selling batch 3's?

You using a sock puppet to shill bid that one too?

Because the ROI chance of making your money back is getting iffy.  Read any of the B3 threads and they are chock full of negativity... though it is in B3's customers best interests to try to get others to refund.  I think most folks are flocking to KnC, bitfury, etc.

For miners that will be at your doorstep within 2 weeks? ASICMiner. You've got those lil 300MH/s USB Block Erupters, or those 5 and 10GH/s blades. However, both are massively overpriced, and will almost never earn back the BTC it takes to purchase them.

BFL is now starting to deliver, but they have a massive backlog of orders to ship first. If you order one today, expect 2-4 months before you get your order.

Avalon isn't selling miners anymore, but instead selling their chips to other people to develop and sell miners. You could start by checking out TerraHash (https://bitcointalk.org/index.php?topic=198489.0), , or there are a [url=https://bitcointalk.org/index.php?topic=253550.0]few (https://bitcointalk.org/index.php?topic=192916.0[Liquid Synergy[/url) different Avalon clones (https://bitcointalk.org/index.php?topic=210186.0). Avalon chips should be shipping in a month or two, and miners based off those chips should start showing up in 2-3 months.

Then there are KNC ane BitFury. Both of them claim to be cheaper than the others, as well as quite a bit more power efficient. Both have some pretty convincing evidence in their favor, but neither have shown any direct evidence of actual hardware (pics, videos, etc). Both of them should be shipping at full volume in 1-3 months.

The first Bitfury chips have already been sent out to and tested by independent forum members. However Metabank won't ship outside of Russia, so you'd have to use one of the proxy-groupbuys. Also Batch 1 preorders are already done and wrapped up if i recall correctly.

Edit: Done and wrapped up as in - No more new Batch 1 orders are taken.

do u know how long takes for a knc mercury or saturn to get roi (supposed the device arrive in october) ?

What I've seen about KNC is they seem to have their act together. Another positive is they take paypal, just the fact that a company is willing to accept the risk of taking paypal give me confidence, as accepting paypal by anyone seems to be a huge risk.

I've ordered 3 of their Jupiter (400GH units) and I'm expecting delivery in October.

With a purchase price of 75BTC (exchange rate when I bought) I can estimate the ROI based on difficulty.

If difficulty is 10x (current 26162876) = 261628760 I would earn 23btc/month. What I need to remember is that the difficulty increase will be slowing % wise as asics are further fired up. While it's not going to take long for the difficulty right now to double, you have to figure it's going to take quite a bit longer to double once it hits  261628760, as doubling from there requires a whole lot more than doubling right now. This slowed increase in difficulty would mean that even at only 23BTC/mo I'll still be making a good amount of coin as the months go on.

I was buying GPUs back when the estimated GPU ROI was 6 months, I came out on top then, If I keep my ROI at 6 months with ASICs, I'm happy, and any quicker ROI is just gravy.

The final thing to keep in mind is that BTC is just going to increase in $ value, thus 1 year from now the amount of BTC to break even will be far less $ cash wise.

I bought a few USB Erupters just for kicks and giggles @ $150 each via eBay. I have faith on an ROI based solely on the anticipation of the $ value of BTC increasing, so BTC mined with the Erupters are going to only be held, and not sold.

you can buy an asic product named Bitcoin, current price $99, best deal out there

KNC does not have actual chips yet.

Bitfury has confirmed working chips and boards: http://www.youtube.com/watch?v=kYyrNhLwrn0. Shipments due next month.

EU customers purchase at http://www.bitfurystrikesback.com/
US customers purchase at https://megabigpower.com/shop/

But at the end if you think a bit about it.. Why should any producer of ASIC actually sell their products as long as they can use it to mine and gain in one week much more money than the mining device actually costs? They all will all wait until time to ROI > 1 Month, and only after that sell the device. I think this is the reason why orders take so long.

In other words:

Nobody would sell a gold pooping donkey until it gets too old and is about to die...

My thoughts exactly! I don't buy that saying 'in a gold rush, you sell shovels'. This 'shovels' are digging on it's own, you just plug them in and delay shipping for a week, or month...

In my opinion, they're all scammers.  If you can't buy it and have it shipped to your house in under a week, avoid.

Who in their right mind would want to do business with a company who talks like this to their customers is beyond me:

When they started denying refunds I think that tells you something is going on.  No honest company with good intentions denies refunds when the customer hasn't received what they paid for.

"You will receive your order in two or more months... "
It would be interesting to see if the percent that get their unit in two months is greater than zero compared to the "more than two months".

Technically 24 months later is "or more months"...

Crazy... misleading... disgraceful.

Sounds allot like terrahash
