Butterfly Labs Jalapeno Asic Bitcoin Miner - Miners don't

Can I use the 5 GH/s Bitcoin Miner from Butterfly Labs to mine dogecoin?

I was just wondering if this is actually possible. I have it sitting here and it is almost useless considering the monster farm of miners you need to mine bitcoin now :/ If not how do you recommend going about mining large amounts of dogecoin?

Proof of hardware and hash rate in images linked above. Note that trail off at end of graphs is from shutting down the miner purposefully.
I am the first owner, and I received this miner directly from Butterfly Labs less than 48 hours ago. I still have the original box, power supply, USB cable, and of course the miner.
After tinkering with it for a few hours I have successfully mined Bitcoins (BTC), Freicoin (FRC), and Zetacoin (ZET) using my MacBook Pro and the miner GUI Asteroid. Pretty cool stuff. I have a few fractions of BTC in my wallet now so I can say that, "I mined cryptocurrencies back when I was your age" to the grandkids one day.
Now that my curiosity is sated, I'd like to pass this ASIC on to another aspiring minetinkeregeek and let them have a go at it. I can offer help if you are running Mac OS X.
If you are in the Seattle, WA area I'll deliver in person and help you get it up and running.

Should I invest in a 5 GH/s Bitcoin Miner from butterfly labs?

i have a bit of money spare and have been intrigued with bitcoins for a few months now.
recently got a new pc. gpu is a nvidia geforce 660, looking to upgrade to a radeon 7950.
i understand the difficulty will skyrocket when asics become available and wondered if its worth me ordering one now. as i live in england the total cost including shipping will be $388.

Decred Journal – September 2018

Note: you can read this on GitHub (link), Medium (link) or old Reddit (link).

Development

Final version 1.3.0 of the core software was released bringing all the enhancements reported last month to the rest of the community. The groundwork for SPV (simplified payment verification) is complete, another reduction of fees is being deployed, and performance stepped up once again with a 50% reduction in startup time, 20% increased sync speed and more than 3x faster peer delivery of block headers (a key update for SPV). Decrediton's integrations of SPV and Politeia are open for testing by experienced users. Read the full release notes and get the downloads on GitHub. As always, don't forget to verify signatures.
dcrd: completed several steps towards multipeer downloads, improved introduction to the software in the main README, continued porting cleanups and refactoring from upstream btcd.
Currently in review are initial release of smart fee estimator and a change to UTXO set semantics. The latter is a large and important change that provides simpler handling, and resolves various issues with the previous approach. A lot of testing and careful review is needed so help is welcome.
Educational series for new Decred developers by @matheusd added two episodes: 02 Simnet Setup shows how to automate simnet management with tmux and 03 Miner Reward Invalidation explains block validity rules.
Finally, a pull request template with a list of checks was added to help guide the contributors to dcrd.
dcrwallet: bugfixes and RPC improvements to support desktop and mobile wallets.
Developers are welcome to comment on this idea to derive stakepool keys from the HD wallet seed. This would eliminate the need to backup and restore redeem scripts, thus greatly improving wallet UX. (missed in July issue)
Decrediton: bugfixes, refactoring to make the sync process more robust, new loading animations, design polishing.
Politeia: multiple improvements to the CLI client (security conscious users with more funds at risk might prefer CLI) and security hardening. A feature to deprecate or timeout proposals was identified as necessary for initial release and the work started. A privacy enhancement to not leak metadata of ticket holders was merged.
Android: update from @collins: "Second test release for dcrandroid is out. Major bugs have been fixed since last test. Latest code from SPV sync has been integrated. Once again, bug reports are welcome and issues can be opened on GitHub". Ask in #dev room for the APK to join testing.
A new security page was added that allows one to validate addresses and to sign/verify messages, similar to Decrediton's Security Center. Work on translations is beginning.
Overall the app is quite stable and accepting more testers. Next milestone is getting the test app on the app store.
iOS: the app started accepting testers last week. @macsleven: "the test version of Decred Wallet for iOS is available, we have a link for installing the app but the builds currently require your UDID. Contact either @macsleven or @raedah with your UDID if you would like to help test.".
Nearest goal is to make the app crash free.
Both mobile apps received new design themes.
dcrdata: v3.0 was released for mainnet! Highlights: charts, "merged debits" view, agendas page, Insight API support, side chain tracking, Go 1.11 support with module builds, numerous backend improvements. Full release notes here. This release featured 9 contributors and development lead @chappjc noted: "This collaboration with @raedahgroup on our own block explorer and web API for @decredproject has been super productive.".
Up next is supporting dynamic page widths site wide and deploying new visual blocks home page.
Trezor: proof of concept implementation for Trezor Model T firmware is in the works (previous work was for Model One).
Ticket splitting: updated to use Go modules and added simnet support, several fixes.
docs: beginner's guide overhaul, multiple fixes and cleanups.
decred.org: added 3rd party wallets, removed inactive PoW pools and removed web wallet.
@Richard-Red is building a curated list of Decred-related GitHub repositories.
Welcome to new people contributing for the first time: @klebe, @s_ben, @victorguedes, and PrimeDominus!
Dev activity stats for September: 219 active PRs, 197 commits, 28.7k added and 18.8k deleted lines spread across 6 repositories. Contributions came from 4-10 developers per repository. (chart)

Network

Hashrate: started and ended the month around 75 PH/s, hitting a low of 60.5 and a new high of 110 PH/s. BeePool is again the leader with their share varying between 23-54%, followed by F2Pool 13-30%, Coinmine 4-6% and Luxor 3-5%. As in previous months, there were multiple spikes of unidentified hashrate.
Staking: 30-day average ticket price is 98 DCR (+2.4). The price varied between 95.7 and 101.9 DCR. Locked DCR amount was 3.86-3.96 million DCR, or 45.7-46.5% of the supply.
Nodes: there are 201 public listening nodes and 325 normal nodes per dcred.eu. Version distribution: 5% are v1.4.0(pre) dev builds (+3%), 30% on v1.3.0 (+25%), 42% on v1.2.0 (-20%), 15% on v1.1.2 (-7%), 6% on v1.1.0. More than 76% of nodes run v1.2.0 and higher and therefore support client filters. Data as of Oct 1.

ASICs

Obelisk posted two updates on their mailing list. 70% of Batch 1 units are shipped, an extensive user guide is available, Obelisk Scanner application was released that allows one to automatically update firmware. First firmware update was released and bumped SC1 hashrate by 10-20%, added new pools and fixed multiple bugs. Next update will focus on DCR1. It is worth a special mention that the firmware source code is now open! Let us hope more manufacturers will follow this example.
A few details about Whatsminer surfaced this month. The manufacturer is MicroBT, also known as Bitwei and commonly misspelled as Bitewei. Pangolinminer is a reseller, and the model name is Whatsminer D1.
Bitmain has finally entered Decred ASIC space with their Antminer DR3. Hash rate is 7.8 TH/s while pulling 1410 W, at the price of $673. These specs mean it has the best GH/W and GH/USD of currently sold miners until the Whatsminer or others come out, although its GH/USD of 11.6 already competes with Whatsminer's 10.5. Discussed on Reddit and bitcointalk, unboxing video here.

Integrations

Meet our 17th voting service provider: decredvoting.com. It is operated by @david, has 2% fee and supports ticket splitting. Reddit thread is here.
For a historical note, the first VSP to support ticket splitting was decredbrasil.com:
@matheusd started tests on testnet several months ago. I contacted him so we could integrate with the pool in June this year. We set up the machine in July and bought the first split ticket on mainnet, using the decredbrasil pool, on July 19. It was voted on July 30. After this first vote on mainnet, we opened the tests to selected users (with more technical background) on the pool. In August we opened the tests to everyone, and would call people who want to join to the #ticket_splitting channel, or to our own Slack (in Portuguese, so mostly Brazilian users). We have 28 split tickets already voted, and 16 are live. So little more than 40 split tickets total were bought on decredbrasil pool. (@girino in #pos-voting)
KuCoin exchange listed DCBTC and DCETH pairs. To celebrate their anniversary they had a 99% trading fees discount on DCR pairs for 2 weeks.
Three more wallets integrated Decred in September:
ChangeNow announced Decred addition to their Android app that allows accountless swaps between 150+ assets.
Coinbase launched informational asset pages for top 50 coins by market cap, including Decred. First the pages started showing in the Coinbase app for a small group of testers, and later the web price dashboard went live.

Adoption

The birth of a Brazilian girl was registered on the Decred blockchain using OriginalMy, a blockchain proof of authenticity services provider. Read the full story in Portuguese and in English.

Marketing

Advertising report for September is ready. Next month the graphics for all the ads will be changing.
Marketing might seem quiet right now, but a ton is actually going on behind the scenes to put the right foundation in place for the future. Discovery data are being analyzed to generate a positioning strategy, as well as a messaging hierarchy that can guide how to talk about Decred. This will all be agreed upon via consensus of the community in the work channels, and materials will be distributed.
Next, work is being done to identify the right PR partner to help with media relations, media training, and coordination at events. While all of this is coming up to speed, we believe the website needs a refresher reflecting the soon to be agreed upon messaging, plus a more intuitive architecture to make it easier to navigate. (@Dustorf)

Events

Attended:
Upcoming:
We'll begin shortly reviewing conferences and events planned for the first half of 2019. Highlights are sure to include The North American Bitcoin Conference in Miami (Jan 16-18) and Consensus in NYC (May 14-16). If you have suggestions of events or conferences Decred should attend, please share them in #event_planning. In 2019, we would like to expand our presence in Europe, Asia, and South America, and we're looking for community members to help identify and staff those events. (@Dustorf)

Markets

In September DCR was trading in the range of USD 34-45 / BTC 0.0054-0.0063. On Sep 6, DCR revisited the bottom of USD 34 / BTC 0.0054 when BTC quickly dropped from USD 7,300 to 6,400. On Sep 14, a small price rise coincided with both the start of KuCoin trading and hashrate spike to 104 PH/s. Looking at coinmarketcap charts, the trading volume is a bit lower than in July and August.
As of Oct 4, Decred is #18 by the number of daily transactions with 3,200 tx, and #9 by the USD value of daily issuance with $230k. (source: onchainfx)
Interesting observation by @ImacallyouJawdy: while we sit at 2018 price lows the amount locked in tickets is testing 2018 high.

Circle introduced USDC markets on Poloniex: "USDC is a fully collateralized US dollar stablecoin using the ERC-20 standard that provides detailed financial and operational transparency, operates within the regulated framework of US money transmission laws, and is reinforced by established banking partners and auditors.".
Coinbase announced new asset listing process and is accepting submissions on their listing portal. (decred)
The New York State Office of the Attorney General posted a study of 13 exchanges that contains many insights.
A critical vulnerability was discovered and fixed in Bitcoin Core. Few days later a full disclosure was posted revealing the severity of the bug. In a bitcointalk thread btcd was called 'amateur' despite not being vulnerable, and some Core developers voiced their concerns about multiple implementations. The Bitcoin Unlimited developer who found the bug shared his perspective in a blog post. Decred's vision so far is that more full node implementations is a strength, just like for any Internet protocol.

FrankenSegwit2x and what I'm going to do about it. (Maybe you too)

  1. Setup a bip148 UASF node
  2. Activate my old 60 gh Butterfly labs miner and connect it to some UASF pool.
Now some of you will say that I'm a naive old-white-man for fighting good connected and financed suits plus their petahash powerful miners with a node and an obsolete miner. You are right but I'm going to do it simply because that's what I can do in this fight for Bitcoin's and bitcoin's independence from the suits. The same suits that ran for generations the legacy banking system and which enslaved generations of hard working "nobody s" all over this planet. I'm going to do my part. What are you going to do?

Minted our first bitcoin this morning! Took about 18 hours (Butterfly Labs Mini Rig SC 500 GH/s)

http://i.imgur.com/LvDPIjY.png
We're using the Butterfly Labs 500 GH/s Mini Rig.
Might as well do a small review -- the hardware itself is temperamental. For example, ours showed up with the unresponsive Nexus tablet on the front panel. Dealing with Butterfly is a total shit sandwich given the rip-and-run state of the overall business, so I had to figure out how to bypass the internal routing and have a laptop be the brains of the operation.
After a couple of days of messing with usb drivers, which refused to stand up on Windows 7, I finally got the laptop to recognize all 8 modules. However, I could not start mining due to an error starting the bfg miner task from the inside of their Easy Miner application. I tried to force bfg via the command line, and it finally worked, although the hash rate was atrocious.
Another day or so, and I had the rig mining. The hardware recognition issue was due to me not giving the laptop enough time to kick ALL modules on. It takes a good 2-3 minutes for all usb notifications to stop bleep-blooping. The hash rate was in the 470 GH/s area, which was perfect, but then the modules started to shut themselves off due to overheating at 83 C. The log would show how the unit was taking down hot modules and then kicking them back on non-stop. The ambient temp in the room is around 75. I played with positioning, fan speeds, to no avail. The hash rate at that point dropped into the 400s, and my 15 amp circuit breakers started to get tripped. This went on for a little, and then I permanently blew one of them and had to pick some up at the Home Depot. But hey, it only took a single trip :)
So then I got a 5200 BTU A/C unit, mounted it in the window, and positioned the rig in front of it. That seemed to fix the breaker-tripping and overheating issues. It runs at low 70s C during the day and low 60s C at night. I am now making custom funnels out of thermal foam board to vent exhaust heat outside and also connect the 11" AC opening to the 16"x16" intake area of the rig (looks something like this). The unit generates a lot of heat, no joke. I bet when the weather gets colder, it can serve as a furnace for this side of the house. If you're wondering why I'm talking about it still not being cold outside in November, I'm in Texas. It's really beautiful right now, high of 75 and sunny.
Also, the noise ... how could I forget about the noise. It sounds like a server room. There's 18 fans, plus PSU fans, and they are quite loud. Don't expect to inconspicuously set this rig in the corner of your living room.
It's been on for over 24 hours now, uninterrupted. To the moon!

The $22,484.00 Butterfly Labs Mini Rig bitcoin miner is a huge, broken, unstable piece of shit.

(This was a rather controversial article posted on Buttcoin.org and became quite popular, even moving to the top of /bitcoin. It's since been mysteriously edited on the site [maybe by g-g-g-ghosts!] so it's being reposted here for posterity's sake. Some numbers may be off by now, but it was all accurate at the time of posting.)
Butterfly Labs has a long and horrible history with their mining rigs. They started taking pre-orders over a year ago, with a ship time sometime in late July. After numerous delays in production, shipping problems and general incompetence, the only thing they’ve managed to get out the door are some of their tiniest miners, the Jalapenos. And those mainly ended up in the hands of reviewers and blogs in order to keep pumping the Butterfly Labs hype train and securing millions of dollars of pre-orders still in limbo.Lucky BFL forums user Luke-JR however scored a sweet Mini Rig from Butterfly Labs (it’s just a coincidence he’s a driver developer for them I’m sure). This rig was originally promised to produce 1500 GH/s hashing power at 1500 watts for $30,000, but has since seen it’s hashing power slashed to a third of what was promised and it’s power consumption increased 75%, now just offer 500 GH/s at 2400 watts. They’ve promised to make good on pre-order buy sending out 3 rigs to match the initial hashing rate, so now it’s only 1500 GH/s at 6900 watts, a reduction in GH/Watt by a factor of 5.
So what does $22,484 buy you? Take a look!
Minirig is here! Today, my Minirig arrived.

FedEx apparently dropped it somewhere along the way, and the weakest part of the case, the thin metal part around the back of the PSU, broke.
http://i.imgur.com/lFcOHxP.jpg
I’m not sure how sturdy the back side was supposed to be, but its two pieces aren’t quite together either.
http://i.imgur.com/AVttcOt.jpg
The power supplies (EVGA 1500W) also created havoc interfering with the neutral on the power line. This disrupted X10 communication significantly enough that the pool overflowed because the system controlling it was unable to turn off the pump. Workaround: This PSU supports 240V, so we rewired the outlet. 240V does not use neutral, so now all should be okay.
Edit: 240V workaround is only partial. Still having problems
But the good news is, it all seems to be working for the most part.
Next up, installing it in the window so the heat goes outside
A twenty two thousand dollar box of electronics that is broken out of the box, that required the guy to do a sketchy electrical workaround to get partially working, that he is going to install in a window… and he’s happy about it?
In case you didn’t notice it, the delivered unit is different than the picture on the website. They had to install 2 power supplies instead of 1 and had to modify the case to fit. Also, if you didn’t notice, the LCD/Phone thingy in the front has been replaced by … a piece of cardboard spray painted black. Wonderful.
You could maybe chalk this up to a careless Fedex postman, but when you’re shipping something that costs as much as a mid-sized sedan, how bought putting a little more effort into packing? Dell and HP can ship bigger and heavier servers across the world without this kind of problem.
The unit had to hit its huge power draw increase by putting dual EVGA consumer grade power supplies in the unit. We’re talking almost a 75 amp load (6*1500/120), disregarding power factor. He could very well overload the circuit panel and trip the main breaker for the house.
Let’s take a look inside this guy.
This is from an earlier version of the Minirig (note the single power supply) This is apparently from an earlier FPGA but it will give you a good glimpse at what kind of craftsmanship you can expect from a computer that is half the average household income in the United States.
Consumer grade PSU and cheap USB hubs glued to the inside case.
Electrical tape and random velcro glued to the insides
A closer look at the USB hubs. Plugs are hot glued to stay secured.
Electrical tape everywhere, splices and voided hardware are the theme.
You can view the entire album here.
Despite all that, this thing can still mine bitcoins and it should be profitable. Keep in ind that many people jumped in on the preorders a year ago when bitcoins were still hovering around $6.50 per. Meaning customers paid 1562 bitcoins for that particular piece of shit, which at today’s value is $156,200. Aston martin money. How long will it take them to make their money back (as apposed to just hanging on to them)? If the difficulty didn’t change, they would make 37 bitcoins a day and recoup the initial investment in 124 days. Difficulty is jumping pretty much 20% every 12 days or so, so in the next week before adjustment, they’ll make 259, the next 12 days 369, the next 12 days 312, then 256, then 213, etc.
So by day 127, they’ll be halfway to breaking even, but by day 151 they’ll be making less than 5 bitcoins a day, and even if difficulty stopped rising at that point(which it won’t), it would take another 435 days for a total of 586 days to break even. If difficulty kept rising at the same pace, by day 200 they’d be making 2.4 bitcoins per day, and it would take 1024 days to break even with no difficulty increase. Assuming 25 cents per kw/h, and $100 a bitcoin, it would cost 0.43 of a bitcoin per day in electricity which means the unit would no longer be profitable on a power usage basis by day 307, at which point it will have produced 2620 bitcoins.
Bear in mind this is only for the first few units, and that’s running 24/7 pumping out around 24,000 BTU, so yes, medical bills from heat stroke will be on top of that.
But Alas, the chips don’t run nearly as well as they’re supposed to, frequently running too hot and giving multiple hardware failures. Coindesk noted in one of the first ever runs of the Minirig by hosting provide gigavps that it was running much too hot and erroring out.
At the time of posting, gigavps warned that the unit would be repeatedly shut down while ckolivas, who was assisting, modified the machine’s software to optimise performance. After some tweaking, the device was said to have been left to run continuously for two hours, and was shown to have an average hash rate of 478.1 GH/s. As you can see in the table below, ASIC number four (of a total of eight hashing chips) ran significantly hotter (86 degrees) and consequently gave the highest hardware (HW) error rate.

So, what happens if you just decide you don’t want this, you don’t want to wait over a year to get a $22,000 broken piece of shit? Nothing, because BFL won’t let you cancel your preorder because they’re now “shipping”, i.e. they sent out one unit to their own company shill.

Which is of course illegal regardless of what Butterfly Labs may say.
So in summary: Don’t buy anything from Butterfly Labs … ever.

USB ASIC Miner 5GH/s

Hi Everyone,
Im new to mining and have been playing around with using my GPU in my home computer. Which gets a terrible hashrate, between 40-50 MH/s. I've been mining through guiminer and slushpool so far as well.
Im curious about the 5GH/s USB ASIC miners from Butterfly labs. Has anyone used one? Will the 5GH/s have a worthy return?
Also looking to get some feed back on using one of these for pool mining.
Any feedback in general on these devices would be appreciated before I send off almost $300. Even if there are better USB ASIC miners for the price.
Product in question

Best way to enter the cryptocurrency playing field?

Just to clarify, this unfortunately is a "how doz I do the bitcoin" newbie kind of post although I initially thought it wasn't
I'm debating getting back into mining and can't decide whether I should invest in a butterfly labs miner or build a mining rig or do some combination of the two.
The things I'm considering are:
A) Butterfly labs miner that I can use as a standalone to mine a small amount, but my question is how competitive will a single 5 GH/s miner be when others will be making similar investments into the same product and the more powerful ones?
B) Building a mining rig and mining BTC until the dedicated miners come out then switch to LTC at that point or
C) Some combination of these options or something I haven't considered yet.
Note: My budget isn't tremendous but it's enough to make a decent investment into a rig or two. My internet and power are free (and no not in the sense of I live with parents so I don't pay for it) which significantly increases my ROI and could make some of these options more profitable than typical cases. I'm not a complete noobie to mining and cryptocurrency but I definitely am not an expert and have room to expand my knowledge and learn if anyone see's anything I'm saying that is incorrect or could be corrected/clarified for me.
I would appreciate any input or advice any miners or investors could offer, thank you ahead of time for anything anyone can offer.
Edit: I'm more newb than I though

Please do not use bitcointalk.org. 55,000 SDC Lesson learned.

Back in 2015 I was THAT person that was victim to a very expensive hack sadly but still my fault nonetheless. I was a huge miner from 2011-2014 of both bitcoin & altcoins. I then stopped due to the power of my 30 gh/s Butterfly Labs ASIC Mining less than it cost to power the thing. So I got heaven into trading cryptocurrencies. I would check bitcointalk.org religiously on it every hour of the day trying to find the newest coin to mine at launch with "promising features". I got heavily invested into Shadowcash. Was the 14th highest holder of SDC on the rich list at the time of the attack. I was very active on their forum as I was a senior member. My username is lawgicc. I had around 55,000 shadowcash staking in my wallet qt on my chrome book with linux installed wallet qt off the shadowcash bitcoin talk. I then decided to put together a gaming desktop. Day of, literally, I am going to install all the software on my new computer & I am scrolling through the official bitcointalk.org thread for shadowcash & somehow downloaded a malware infected wallet qt that was identical. I was careless & downloaded the link off of a repost of the official dev rynomaster. As shadowcash was constantly being updated rynonmaster would post the most recently updated wallet qt in the so called "moderated" forum. So someone required Rynomasters most recent wallet update post and infected the link that was in rynomasters requoted text. My rig was obliteratedZ DClogs & all. As soon as I installed the identical malware infected wallet qt (with no problems) I entered my paraphrase into my the wallet qt to stake my coins...wake up the next morning to 2 transactions 55k worth of SDC gone. I flipped out & contacted everyone asap tried to get the blockchain re rolled but they only offered to post a donation link to help fund my stolen 55k. I worked hard trading for those coins and boom just gone like that. I believe it's around 96 bitcoin worth. It really made me bitter toward trading alt coins. I still get salty til this day that I thought I could trust people. It's crazy how careless people can be. I had another 25 bitcoin locked on mt gox cause I'm genius. Still have not lost my faith bitcoin. Sucks people have to scam. I was 23 years old when this happened. Don't think I'll trade again. Be safe out there traders! Remember one thing .. HODL BITCOIN!!!!!!!

Why aren't more people worried about the security risks of ASIC miners?

Butterfly Labs is selling an ASIC mining rig that supposedly does 1,500 GH/s for only $29K (Able to earn more than $5K a day in BTC at current difficulty and market value of approximately $35/BTC).
The current global hash rate is only sitting around 35,000GH/s, so a single enterprising individual could theoretically buy (or build) 30 of these ASIC rigs and essentially control more than half of the global hashing rate.
Correct me if I'm wrong, but couldn't this person (or group of people) then quite easily execute the infamous >50% double spending attack on the network? https://en.bitcoin.it/wiki/Double-spending.
The current market value of of all the Bitcoins out there is supposedly hovering around $340 million dollars (according to Bitcoin Watch). With that kind of money on the line, is it really so hard to believe that an enterprising group of people might not be tempted to jump at this sort of opportunity?
This worries me.

Raspberry Pi & ASIC combo?

I have a Raspberry Pi and want to learn about bitcoin mining so I am looking to get an ASIC miner for educational purposes. I'm not trying to spend a ton of money so I was thinking of getting a Butterfly Labs 60 GH/s off of ebay.
Are there any other ASIC miners I should be looking at that's compatible with the Raspberry Pi?

Monarchs Shipping

Great news! Butterfly Labs is Shipping Monarch Bitcoin Miners
Monarchs run at 700 GH/S with a power efficiency among the best in the industry at 0.70 W/GH. As a reward for our customers’ patience and loyalty, we are adjusting hashing power for existing orders in the queue to $1.97/GH (for 700 GH, effectively $1,379). Shortly before a customer’s order is ready to ship, they will receive details about their individual options.
Those who have closely followed the Monarch development will notice that the 700 GH comes in above the 600 GH performance specification we originally mentioned, but below the 1TH/s level we are aiming to achieve based on the strength of the underlying ASIC chip. While we have achieved much higher speeds on test boards, our engineers are still working toward a board solution that will deliver higher speeds within the power consumption, and the temperature range required.

Asic Mining Cards

If and when I receive my 600 GH/s asic miner in January from butterfly labs, approximately how many bitcoins will I mine per day at the difficulty then? Anyone know a calculation for me?

Any Halfway Reputable ASIC Miner Retailers?

I'm interested in purchasing a small ASIC Miner for the sake of having some stake in the Bitcoin network other than just HODLing, reading the news, and hoping a merchant I use will actually start accepting Bitcoin.
Poking around on the Internet, I haven't found any ASIC retailers that looked remotely credible. The reviews of Butterfly Labs are terrible, taking months or years to ship products, and everything they listed was out of stock. The Antminer ASICs I saw on bitmaintech.com were far more than I was looking to spend. Other websites looked sketchy at best. I've read several reviews of people who got ripped off, or waited months for their products to ship.
I'm not under any delusion of making my money back. But I'm not opposed to putting a few hundred dollars into an ASIC that outputs a few hundred GH/s and uses less than 30 kwh/day in power... if it is likely to actually show up.
Any thoughts or recommendations on where to look?

How to Cancel My BF Labs Order?

Hi Reddit,
On May 6 I ordered the 5 GH/s Bitcoin Miner from Butterfly. I paid using PayPal, to the sum of $308.00. After a little over a month, I contacted them asking where my item was. They responded that I was given an order estimate of over 2 months and that my order status could be checked on their site (always "processing").
After 2 months, I started asking again, and it took them quite a long time to get back to me. I also had read within the few weeks before that of BF Labs' troubles, having come here and seen in the NY Times. They finally got back to me last week and told me that they could not provide me with any sort of shipping estimate, but they'd tell me when my item ships so I can track it. I told them that due to the time-sensitive nature of the product (aka it gets less valuable the longer I wait) and their inability to even give me some sort of estimate on my purchase, that I wanted a full refund.
They told me that I agreed when I purchased it that all sales were final. I went to my bank but they informed me I needed to go to PayPal since they are the ones who did the transaction. PayPal told me that they don't handle disputes for hardware/software since "it is usually a misunderstanding." They said I could send a letter to the company, which I did, and then PayPal immediately closed the case saying it was more than 45 days since the transaction.
So, whether or not any of you think I "deserve" a refund in this case, I am still going to attempt to get myself one. I think most people can agree that buying products where you pay up front and receive what you paid for "sometime in the future" is not an appropriate business model.
Now that my bank and PayPal and the company won't help me, what can I do to get my refund? The Better Business Bureau? FTC? I really have no idea.
Thanks for all your help, guys!

New to the Bitcoin. Have a few questions.

So after having heard about Bitcoins on-and-off for over a year, I finally decided to see what the all the hype was about. The currency look really interesting, especially how it can be generated, but because my Macbook Pro hardly has the potential for efficient Bitcoin mining, I did some research and found the ButterflyLabs 5 GH/s Bitcoin Minerfor $274 + shipping. However:
• There have been many discussions about horrible backlogs and wait-times on orders of any dedicated Bitcoin mining machine. How does this model compare? Will I be waiting months before it ships?
• I looked at some online calculators, and they said I should be able to have a net gain after about a month. Should market conditions be consistent enough to reach this timeframe?
• I like the idea of solo mining over pools. However, which is honestly better?
• Would Bitcoin mining on this hardware even be worthwhile? How skeptical should I be of Bitcoin mining in general?
Thanks in advance :)
