Re: Official BITMINE CoinCraft series 28nm ASIC miners thread
Trial is still ongoing to try to recover the millions Bitmine injected in their Icelandic project...our money.
Hey Jey,
I was trying to find more info on bitmine.ch (I never received my order/refund). It still seems like a black hole in terms of info, at least from my perspective in the US. What is this mining project you mentioned they invested in? Any updates beyond that? Thanks
Thank you for all the feedback and suggestions!
Did the site expire or did you take it down (on your own will or at someone else's)
Was your case resolved? Trying to put some pieces of this back together.
Thanks
Selling my fleet of miners. 
I have 7x Bitmain S3 (6th batch) [I am currently planning on keeping two.]
https://www.bitmaintech.com/productDetail.htm?pid=00020140805174119025527O4H3705C5
Planning on keeping the 4 PSUs (Corsair RM850) - open to offers
http://www.corsair.com/en-us/rm-series-rm850-80-plus-gold-certified-power-supply
Housed in cool dry conditions, never overclocked. All still running stable, no dead ASIC chips.
One miner had dead intake fan, was replaced with a Noctua NF-F12 iPPC-3000 PWM 120x120x25mm Case Fan
http://www.newegg.com/Product/Product.aspx?Item=N82E16835608052
Available for pickup in San Francisco or item will ship in original Bitmain box via UPS ground.
No power supply included, unless you can convince me.
No lowballs please.
Picture when I first got them (slightly dustier now, but will be cleaned):

After one year of mining, I just stopped my small time mining operation 
In the past 4 months, I was paying so much for power, my bills were so high, and I was barely making anything. Not even close to breaking even each month. Now I just buy direct, and cloud mine. I have to keep the feeling of getting new coins each day. I think I will turn on my miners maybe for a week each month (maybe).
But I will say what a year experience it has been. From being ripped off and miners never coming that I paid for from minersource/blackarrow (prospero x-1), and from cloud mining sites shutting down after 2 months of offering service (GAW miners).

I am on the fence of shutting down my 7 S3's - I live in SF and feel like I am actively losing money, but I enjoy doing what I can to decentralize the network.
I wish it wasn't so slanted by silicon/ASIC producers with access to cheap power.
I also got ripped off $6000 by bitmine in 2014 with a miner/refund that never came.
I wish there weren't so many bad people motivated by greed in this world.
I still believe in bitcoin.
maybe offtopic but what was the deal about the $6000?
I purchased a CoinCraft Desk miner from Bitmine.ch in 12/31/2013 for $5,938 USD - sent by wire to Switzerland. The miner was supposed to be delivered in March 2014. It never came. The company just went public with its bankruptcy.

Also feel free to check out a bunch of their customers complaining about never receiving the miners or the refunds they were promised.

edit: dates
The only way you could pay more to mine is if you moved to Hawaii or New York City.
Hawaii it is!

Re: WhoMined.com -- data on which miners mine which blocks
Sweet site. Great idea snd good stats/info. It is pretty straightforward, but the UX needs work. Design, ad placement, and especially colors need some attention. Let me know if you need help. Thanks & keep it up!

thanks! those extra ips helped.
I used textedit on mac, opened a new plaintext document, pasted this in and threw it into ~/Library/Application Support/MaxCoin/ titled "maxcoin.conf"
Ahh Burning Man! Thanks for volunteering me Charlie
Such a trip will be absolutely fantastic under the following conditions:
1) First and foremost, the purpose has to be to go with bitcoiners as a social and networking and ideating activity. We'll be able to talk bitcoin all day long among ourselves and I'm sure some great work would come out of it. BUT - we will not (and should not) be able to "sell" or promote bitcoin at Burning Man in any visible way. If it comes up in conversation with outsiders, that's great, but we can't be there to evangelize. So to the extent that it's partly a business trip, the business would be primarily limited to internally within our group, not externally toward other burners. The event is explicitly "money free" and "promotion free"... and if we're promoting money then we FAIL doubly With that said, many burners would be interested in a counter-culture monetary system - so hopefully lots of organic conversations could happen.
2) There's actually an issue of ticketing this year... basically the event has gotten so large that there are not enough tickets. Because the operators don't understand how price mechanisms work, they thought it'd be better to distribute tickets on a lottery system than by raising prices to curb demand. Any free-marketer would be able to predict the outcome - shortages! I have no idea how to get tickets this year, and it might be impossible to do in any coordinated way for a group of us. So, this might be a problem :/
3) Burning Man is absolutely wild and awesome and interesting (just like Bitcoin). I can think of no better way to spend a week with fellow bitcoiners. But, it's intense, and requires lots of planning. Cannot be done last-minute. Requires commitment and dedication.
4) A nice RV is mandatory... fuck tents in the hot sun. A/C, showers, and cold beer

Well stated. This sort of idea should be put into the glam campbitcoin website somewhere.
It should be a regular power cable, but your circuit breaker (http://electronics.howstuffworks.com/circuit-breaker.htm) is the thing you need to keep an eye on.
A standard household circuit that gets distributed to one or more rooms (sets of outlets connected to one of the circuits) is normally 20 amps (2000 watts) and is written/printed on the switch on the circuit in the breaker box (http://www.homedepot.com/catalog/productImages/300/e6/e693993f-67ed-4fb0-9ab9-8b90c01881c2_300.jpg)
Running a 30 amp hashing system on a 20 amp circuit will probably blow the circuit as soon as it gets going. If you underclock it to use less power you could probably get it under 20, but you bought 30 amps worth of hashing power.
Bigger circuits are set up for rooms with needs for more power, like laundry room or kitchen. You can add or replace circuits with beefier ones, but you should hire an electrician to do this if you don't know what you are getting into. If you choose to do it yourself, just make sure to turn off the power so you don't kill yourself.
Good luck!

It will degrade over time for sure, but the recent series of downspikes is from a multitude of things.
People were getting weary of cex.io/ghash.io having the market share on mining and harnessing 51% of that power can be a bad thing as they could potentially control the blockchain for a period of time. This is from the wiki:
An attacker that controls more than 50% of the network's computing power can, for the time that he is in control, exclude and modify the ordering of transactions. This allows him to:
Reverse transactions that he sends while he's in control
Prevent some or all transactions from gaining any confirmations
Prevent some or all other generators from getting any generations
The attacker can't:
Reverse other people's transactions
Prevent transactions from being sent at all (they'll show as 0/unconfirmed)
Change the number of coins generated per block
Create coins out of thin air
Send coins that never belonged to him
It's much more difficult to change historical blocks, and it becomes exponentially more difficult the further back you go. As above, changing historical blocks only allows you to exclude and change the ordering of transactions. It's impossible to change blocks created before the last checkpoint.
Since this attack doesn't permit all that much power over the network, it is expected that no one will attempt it. A profit-seeking person will always gain more by just following the rules, and even someone trying to destroy the system will probably find other attacks more attractive. However, if this attack is successfully executed, it will be difficult or impossible to "untangle" the mess created any changes the attacker makes might become permanent.

Check out https://blockchain.info/pools for a pie chart. Also: https://en.bitcoin.it/wiki/Comparison_of_mining_pools for more info.
People moving away pushed the value/price down and that drove more people away, like a downward spiral. Still in the middle of that now.
In the end it is bringing the price down for hashing power, which is good for you.
