All these calculations are worthless.  You forget you can sell your miner.  In any case, an s1 today is still profitable with decent electricity rates with undervolting (I<m assuming it still it, maybe someone knows for real, im tired dont feel like doing some math).  also my miner heats my garage/house, so you have to factor that in too. 

Also its a lot more fun than a simple garage heater, which costs money for heat.

well it would have to be well built...i mean all the vibration and the bumps, etc.  Plus you would need an extra battery or something, I suppose it would keep the alternator on too much.

Well not really, because you sell your miner after.  So you sell it for 1000$ maybe, there is 400 profit.  and if btc price goes up, then you make more.

No...no....I would not do that.....a 220v line needs two 110v lines.  It doesnt matter whether the little chinese fire box outputs 100000v, what matters is that your antminer is pulling about 1300w or more.  So what really matters is what wire you have going from the plug to the breaker box, including all other appliances/things that are plugged into that circuit.  So lets say you have a standard 14 wire, with a 15A breaker..you could put an antminer on it, but you are cutting it close to 80% load, which is pretty much the maximum always on load for a 15a circuit.  Better be safe !  As for chinese made stuff....I wouldnt trust that stuff unless it has real certification, idk what they are, like CE or something like that.  my2cents

Cryptocurrency, bitcoin included, is great to buy goods and services on a global level.  If I am canadian, buying from china for example.  I have to convert to usd, then send it, then they convert it back to their local currency.  with btc its simpler and the fees are lower.  transaction times are fast compared to a wire transfer.  Also its peer to peer, no passing through a bank or other intermediary.  The block chain tech is useful for record keeping and it is safe, secure, fast and innovative.  I have bought many things, usually with dogecoin as transaction times are much faster.  Those that say its just a store of value are wrong.  Bitcoin derives its value from its usage and how useful it is.

Id recommend Kano.is pool, stats are fast and good.  pool runs great.

yeah since its not connected to the motherboard....the psu wont turn on ! 

hmm well they messed up if they send a bill AFTER giving you the miner....I say forget the bill until they really start bothering you to pay.  You will probably get some automated phone call in a while.

Ok, thanks for the info!  much appreciated

Hi guys.  I just turned my s7 to the pool ヽ༼◕ل͜◕༽ﾉ and I have a smallish question.  I set min diff to 4096 but I'm sure its supposed to be x2 or x4 higher, I know the pool adjusts it automatically but i've been on it for over 5 hours and it hasnt.  So question = what diff should I manually set, or put it to 0 ?

I switched to Kano pool, looks good, I like that stats update really fast, and you have lots of them.  UNFORTUNATELY, I had to change settings in the antminer batch 8, big mistake, as it took many "soft reboots" and 2 actual "reboots" to get it at 4720ghs, with good hw.  I also see lots of X's for the chips, but thats just a bad reading or something because the hashrate is good and it goes away after 5 minutes.  

Note to self:  dont ever change anything in the settings ever again.  ever.

you need over 200v, or else it will turn on but will not power the antminer s7.

You may be right.  After all, they will need to cash out at some point

Bitfury will not be listed on the NYSE....going public means having top notch and clean operations and finances.....verified finances.  Reporting obligations.  Regulation by SEC and others...methinks Bitfury is full of crap, and = "oh invest in us, we got all these new products, hype hype hype such wow, and you'll cash out and make a killing when we get listed on the NYSE, give us money money".  my 2cents, I smell the bullshit from here.

You could always mine some low diff altcoin with the s1, and hope the price jumps in the future.  Other than that....what if btc price goes up ?  then your small amounts of btc are worth something....so dont mine at a loss, but why not if the profit is small ?  Also, you may consider to mine solo (solo ckpool for example) and have a little lottery thing going on.  I sold all my old miners, but I did keep a usb block eruptor for posterity. 

It can be done with the 1300w, see dogie review of the antminer s7.  he plugs only 2 pci per board with the 1300w evga.  but this voids the warranty I think.  (touching the machine voids the warranty lol).  Else get the 1600w evga, its a beast and it has all the pci cables you need, but its expensive.  good thing it has the 10 year warranty too.  Other than that, you have to get a server psu (loud) on 220v. 

I think its more about the blockchain, they are seeing if they can use it in their business.  for example a lot of OTC contracts are traded, swaps, etc.  these are cleared by a clearinghouse and you have a lot of credit risk, counter party risk, etc.  But with the blockchain...it could change a lot of things for them.  I dont think they care about bitcoin.

yeah its frustrating...something must be done.  But then again, you must pay at least 0.0001 btc or something like that as a fee.  so 5 cents.

Speaking of duties and fees, taxes and such.  I paid 330$ cad to DHL...Im filling a CBSA informal adjustment request form to the customs agency and I hope i'll get 2/3 of that refunded.  You can also dispute the Merchandise value that bitmain put on.  I will do that too, as they put 100$ usd or so more than I paid.  I'll let you guys know what happens, (probably in a few weeks...months) if you are interested, this is for people in Canada (im in quebec so i paid quebec tax too).

Anybody else think that current antminer s7 / avalon production is bumping the diff a lot, and that this is hurting big time bitfury's profits and older gear profitability....I'm just saying, knowning how this world works, I wouldnt be the least surprised if these anouncements are made only to make people delay or suspend their own purchases or data center plans for bitcoin, to make them "wait" or rethink their own profitability....so that the diff rises a little less and bitfury makes a little more money, for a little longer.
