Bitcoin Mining Hashrate and Power Analysis BitOoda ...

Bitcoin Tax Attorney here. I am around for discussion or questions related to Bitcoin Tax treatment, including tax planning opportunities for businesses and individuals.

Anyone have issues with their tax returns due to lots of Bitcoin usage or from the sale and disposition of Bitcoin? Anyone looking for any tax favorable planning opportunities? Either as an individual who sold a bunch for profit or for a business who has begun accepting Bitcoin for the first time.
My practice has focused on helping both individuals and businesses for Bitcoin tax related matters for much of this year. I am available for discussion here in the comments, and for more specific matters, please PM me.
I'm a tax attorney based in Los Angeles and big bitcoin fan and miner going way back. I've been lurking hear on bitcoin for years. I was a miner back in 2011-2013, build my own custom rigs with 6 Radeon 7970s.
Then I was among the first to receive a couple of BFL's 5 gh/s cubes and then one of the first 50 Gh/s. (I knew that was a lawsuit waiting to happen against BFL. Scoundrels) Good memories all around. I still have my spreadsheets keeping track of what I mined. Altogether, with the pools, I mined over 100 bitcoin. Alas, I sold many of them when the price was $300 or less.
All this time I was focusing on tax law, finishing Tax LLM courses in Los Angeles. So, it was inevitable that the two interests would merge. I ended up writing a proposal to treat Bitcoin as currency as opposed to property.
Here is a link to my paper on this which Tax Notes published as their cover story a few months back, which was completely unexpected but kinda cool to see this niche interest rewarded.
Paper: "Bitcoin: Property or Currency?"
Got to go on a State Bar Delegation to DC to enlighten folks with the power to actually do something about it. Delegation met with IRS Chief Counsel, including people who drafted the Notice treating Bitcoin as property. Also folks from Treasury Dept, Senate Finance Committee, House Ways & Means, etc.
I urged for currency treatment (as opposed to property treatment) of Bitcoin and other cryptocurrencies, in fact anything built on the basis of the Blockchain meant as a mode to transact money.
If any of you guys had to do your taxes this year, and have bought and spent a lot of Bitcoin, or even just mined and sold, you probably know some of the difficulties I'm alluding to without even mentioning.
Should we really have to calculate capital gains/loss on the purchase of a cup of coffee at your neighborhood cryptocurrency friendly coffee shop, for example? Even with purchases at or Dell, you were technically supposed to calculate capital gains and losses and provide supporting backup on your tax returns this year.
What a practical and administrative nightmare for both taxpayers and for the IRS who has to wade through this. I feel like some of what I wrote got through to them. As we all know, government lags far behind emerging technologies. But they did seem genuinely interested, and I do not believe my paper and proposal fell upon deaf ears.
I have my own law office these days and work with or for many attorneys on various matters, just as I have a number of attorneys assist me. No such thing as a pure solo practitioner these days. No man can afford to be an island.
This tax year has been very rewarding and helped a great many tax clients with Bitcoin issues from anything to bookkeeping to strategic planning for the short-term as well as long-term.
Any accountant knows the terms LIFO and FIFO, but there's seemingly no hard and fast rules for measurement for when a particular bitcoin was bought and sold for purposes of calculating gains/losses. Also, no hard and fast rules as to where the particular market price of Bitcoin is found on a particular day.
Everything is loose, open to interpretation by the tax payer, and with strategic guidance, can prove incredibly tax favorable ultimately. It is wise for a business to accept Bitcoin for many reasons, including that broad opportunity for interpretation while staying true to the property guidance.
So, it is ultimately very taxpayer friendly due to this broad leeway. More than that, treating bitcoin and cryptocurrencies as property rather than currency is also taxpayer friendly by definition. Your bitcoin gains will only be taxed at your capital gains rate instead of as ordinary income, a higher rate.
I assisted a lot of individuals and even businesses who accepted bitcoin for the first time this year. I intended to post on /bitcoin before to offer my services and to also just allow people to send me questions, which I am happy to discuss in private for free.
I got pretty slammed up to tax day, but I'm free now. Just hit me up by private message or shoot me an email at thebitcoinlawyer at g mail.
Any questions or thoughts, I'll be around. I'm often around /bitcoin anyway. Love this community. And if I can serve as help for any of you, all the better. Thanks.

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 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.
I’m not sure how sturdy the back side was supposed to be, but its two pieces aren’t quite together either.
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.

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.

Thousands of bitcoin and other cryptocurrency miners all over the world are operating their own setups, using power sources linked to high-tech devices to be constantly mining, constantly earning. But within this competitive industry, it is often a race to maximize efficiency and profits while minimizing cost of operation and power usage. Is it possible to tell cgminer to only use about 50% of my GPU so that the lag is gone for normal work. ( I dont play games while mining ) ( I dont play games while mining ) Also, is it possible to start cgminer from a batch script without a window, so that when the script executes there is no window but it creates the process and starts mining with the given data etc.? When Satoshi gave the world Bitcoin back in 2009, it was easy enough to measure hashrate in hashes per second because the computing power on the Bitcoin network was still relatively low. You could mine Bitcoin on your home computer and it was quite possible and likely that you would occasionally earn the then 50 BTC block reward every so often. A Bitcoin ASIC miner will, once turned on, not be switched off until it either breaks down or becomes unable to mine Bitcoin at a profit. Because of this, Bitcoin miners increase both the baseload demand on a grid, as well as the need for alternative (fossil-fuel based) energy sources to meet this demand when renewable energy production is low.
