eBay
Auction is for a certificate of per-order for the Butterfly Labs, Inc. 5GH/s Hashrate BitCoin Miner. When I receive the hardware for this pre-order unit, I will forward the Butterfly Labs 5GH/s Bitcoin Miner (SKU#: BF0005G) directly to you using Priority Mail (anywhere in the lower 48 United States). The device will be unopened and in 100% of the original packaging.  Their box, my shipping label.

If you weren't lucky enough to get in your preorder's early, you could be waiting an extremely long time to get one of these, so this will get you one quicker as you'll receive my order when it comes in and since I've already ordered, you'll be able to get one  sooner then if you ordered one now.

This device is a simple, efficient way to mine bitcoin.  No video card customization, no hardware assembly, no special video drivers!  Simply plug the device into a free USB port, and install the included software, and you'll be mining Bitcoin more efficiently  than any current GPU miner.  It use cryptographic processors specifically designed to do nothing but mine Bitcoin as fast, and as efficiently as possible.  Since these devices are smaller than a full mining PC they can be run in environments that GPU miners can't, including in an office environment where it can run 24/7 without running up a home power bill. There's no reason to have a room full of PCs after these devices hit the market, but the earlier you have one, the more profitable they will be.

This auction is for my pre-order, below are the details for the Butterfly Labs 5GHz ASIC Bitcoin Miner, that you will receive as a pre-order owner, as soon as Butterfly Labs Ships it.

ASIC Miner details: Size: 100.32 mm x 100.32 mm x 17.1 mm Processing Power: 5 GH/s (+/- 10% running variance) 

ASIC Miner Included accessory:
 Two (2) USB Cables Plug the USB cable into a host computer and run the supplied software. Additional Bitforce SC products can be added to the chain via a USB hub for linear performance multiplication with no overhead cost. Each additional unit is auto-configured and folded into the workforce without any user intervention required. 

ASIC Miner Warranty: This unit’s system board has a lifetime warranty from manufacture defect or component failure. From Butterfly Labs - 

ASIC Miner Pre-order Terms: Bitforce SC (ASIC) products are in final stage development with initial shipping scheduled for the last half of April 2013. Products are shipped according to placement in the order queue, and delivery may take 2 months or more after order. All sales are final.

Bitcoin Profit Considerations:

These are the important figures right now (7 Apr 13):
  • Network Hashrate: 61.409TH/s
  • Difficulty: 7,672,999.92
  • Block Reward: 25 BTC
  • BTC/USD Rate: $140.00 USD 
Using those figures, and assuming you had your own BFL SC, you could expect approximately 119BTC (USD$16,746) per month. BUT ... the network hash-rate will be much higher once ASICs hit the mining scene so taking that into consideration, we should factor in a jump of difficulty to cater for the increased hash-rate of 1000% (10x) in the short term. Current price (MTGox) for BTC is USD$144.0001. So, using that information, and for estimation purposes a flat rate of USD140 per BTC, an possible assumption to make when working out your mining returns is USD287 per month per GH/s (@ 7 Apr 13)

Income per month for the BFL ASICs (using the above) with no overclocking and ZERO power costs in USD is would therefore be around
$1,255/mth  
Bear in mind these are laboratory examples (i.e. in a perfect and controlled world) and your returns may not be this high. Actually, it's almost guaranteed you will never see these sorts of figures as there will be a whole heap of ASIC's hit the market which will dramatically affect hash-rate and difficulty. These values will fluctuate daily as the market value of BTC fluctuates and hash-rates/difficulty changes. If you want to run your own calculations check out many of the BTC calculators online ranging from simple to complex. Here's an example to start you off:http://bitcoinx.com/profit/


This is not a guarantee of income, and there currently is not a guaranteed ship date for any Butterfly Labs Products.  You accept all risk of profitability, or loss.   I am selling my pre-order, with the physical hardware to follow when and if Butterfly Labs ships it.  You will receive a physical copy of paperwork shortly after you winning bid, with the actual hardware to ship out the same day I receive it.  Butterfly Labs current estimate (April 7th, 2013, is between Late April, and July, but they may change).
