Pretty much there is a simple rule:

1)  If they offer cloud mining, they will make money, you may or may not. 

Look at the fairly recent Kodak farce:  Relabeled S9s, you pay over $3000 (more than the cost of the units), they run them, you get half the PROFIT (so amount made after their electrical cost, if any).  Pretty silly.

Ok, got a bit of sleep after an all-nighter.  Let me expand on this a bit:

I WANT BlokForge's prices to be a bit higher than Canaan's site.  Perhaps they get a distributor discount, perhaps significant, perhaps not, but they have to make a profit to stay in business.  Plus, by utilizing them I save the (admittedly small) hassles of working with Customs (Fed-Ex does 98% of that work for me), and they include shipping - something they paid for to get the units from China, and something they pay for to get the units to me.  Nothing is free, so its only expected their prices will be somewhat higher than whatever Canaan is advertising.

Need some coffee...  sorry if that is a bit garbled.

I'm thinking you didn't wait long enough - like 15 minutes - before checking the status.

Its possible your company has a "mostly closed" firewall, but that is somewhat unusual.

That said, stealing electricity from your employer may change your relationship with them.

And me.  Not even going to complain about the price drop on the Canaan site - because I can't afford 60 of them!

Fascinating.  Guess I'll stick with my plan to use up my old Raspberry Pis and keep the chains short.  Any idea is the hash loss is caused by under performance of the Pis, or something else?  Just wondering if I should spend the relative pennies and buy faster Pis?

And if I Bitmain S9 burns down my farm here in the USA you really think I could hold a Chinese company accountable?

I ended up ordering (10) 841s from Blokforge and taking advantage of their buy 10, get 1 821 free offer.

Bought (2) L3+s from Bitmain yesterday just to burn my $450 coupons.  I haven't fooled with Litecoin since 2014, and the L3s obsoleted my idle Black Widows when the they came out.  So now I just have to wait a couple of weeks.  Litecoin seems to be a step ahead of Bitcoin in development, so figured I would SLIGHTLY hedge my bets.  By April 24th, I should have (2) Litecoin machines and (122) Bitcoin machines (I did say slightly).  Mostly it just helps keep me from getting bored.   I have one (6) 1070ti GPU machine as well churning on zcash.  Syncing Viacoin, Dogecoin, and Pesetacoin since they can all be merged mined with Litecoin.  Somehow that concept feels like cheating, but what the hell.  It will help keep my mind from stagnating, or at least from stagnating faster.

Regarding a 1 year ROI - I wouldn't bother calculating it.  Personally I like 100 day ROIs but those days are pretty much gone.  In reality, unless you can accurately predict both difficulty change and future coin price, any ROI calculation would just be a guess or otherwise meaningless number.  Cryptocurrency is pure speculation but a lot of fun along the way.

Great to hear!  My electric bill has a monthly peak demand component to it, that toggles around the 23rd of each month.

I always find it annoying to have miners ready to turn on and have to wait a week for the new period to start.  Breakeven for me is around 8 days, so here is hoping delivery is closer to the 1st!

That, and of course, I'm anxious to play with my new toys...

ps.  Tonight is the night!  Shortly after midnight I'll be toggling on my last batch of miners.

I am under the impression Awesome Miner is free for up to 10 miners.  I find it well worth the fee for managing my 100+.

Nope.  Technically they should not be working.  Can't argue why they are.

Listen to Fanatic26.  He speaks the truth.  You do not need to open any ports for your miners to work just fine.

Looks the same as mine.  Still clueless why your miners are running ok.

Downside of a truly zero fee pool is there is no incentive for the operator to run it and pay all the expenses, or to further develop it.

Still really confused on why your APW3++s are putting out the required 12V power at 110V input.  Could you link a photo of the label on the side (the one that shows the power specs).

They are giving them out to existing customers.  Happy to pass $100 ones onto you as a Kano member bonus (or to anyone else here).  Just PM me your Bitmain account name.

Think its more like "Lets try and retain some customers"...

That makes sense... thanks for the explanation.

I believe that any imbalance would only be felt downstream - at your providers UPS or transformers.  Normally balance between legs is more of a goal than an absolute requirement.

Can you do me a favor?  Stick a voltmeter into one of those 110v sockets...

I'm having a problem with the concept of the power strip providing BOTH 110V and 208v at the same time.  My guess is that your 110V sockets are providing 208V...  my guess is that the 110V sockets are just for the convenience of using more common plugs.

And THAT has got to be the absolute safest way!

Not likely.  They will run on 110V - but can only produce about 1200 Watts at that voltage.  They require 220 (suspect 208 should be fine) to output their full 1600 watts.

Lets see (run and grab a spare)... ok:

Input: 100-140 VAC - Output:  12V DC 100A max (e.g. 1200 watts)
Input: 200-240 VAC - Output:  12V DC 133A max (e.g. 1596 watts)

So yes, 208 SHOULD be fine, but Bitmain runs a bit loose with their specifications.  Like only a fraction of the power supplies will start at 0C.
