I'm biased because I run my own pool.

However, all of the choices you've listed are pools that use mining cheats (i.e. SPV mining and empty blocks).  Further, there are hidden fees associated with those pools.  For example, Antpool might say they're a 0% PPLNS pool... however, they keep all block transaction fees for themselves.  Currently, the average is about 4%.

Please don't confuse "biggest" with "best".

Those statistics are meaningless, except to give you visual reassurance that the miner is working.  In pooled mining, every miner is compensated based upon the work the miner submits.  In variable diff, the pool determines how "difficult" the shares it will accept from the miner are.  It bases this on figuring out how many shares the miner is submitting in a given time frame, and adjusts it according to how many shares the pool wants to accept in that same time frame.

Let's take BTC mining as an example.  A pool wants to get six shares a minute, which translates into expecting to receive one share every 10 seconds.  You have an S9, which hashes at 13TH/s.  You can calculate how many diff 1 shares that miner expects to solve per second based on the following formula:
So, for our S9 at 13TH/s, we can see that it expects to solve 3026.8 diff 1 shares per second.  That's considerably higher than what the pool wants to track, so to compensate, it adjusts the difficulty of the share it will accept from the miner.  As difficulty increases, the number of shares solved per second decreases.  To get to our target value of 0.1 shares per second, we simply solve for difficulty in the above formula:
In this case, the diff would be adjusted to 30268.  This way, every time the miner successfully solves a share of that difficulty or better, the pool records the miner having submitted a share.  The pool will typically constantly adjust that value based upon how many shares the miner actually has submitted during the time period.  If it has gotten more shares than expected, it will increase the difficulty.  If it has gotten fewer, it will decrease it.

All of that data is collected, and when some miner finally does submit a share that actually solves a block, then the pool calculates how to distribute the block reward amongst the miners.  That distribution is based on whatever payout mechanism the pool employs.

That's all well and good for pooled mining, but when you're solo mining, none of it matters.  You can submit a trillion shares and not find a block.  Or, you could submit just a single share and that one solves a block.  No matter how many shares you submit, the only one that will ever matter is the one that solves the block.  When that occurs, the pool will distribute the reward.  Either the pool generates the reward to its own address, then pays out later, or more likely the case in solo mining, the reward is distributed to you as the coinbase transaction.

The values you're seeing in the screenshot you shared are there purely for you.  It's a reassurance that your miner is working by providing a visualization of things.  In the screenshot, the pool has assigned a difficulty of 8 to your worker, and that worker is submitting 15.87 solutions per second.  None of that means anything to the pool, or to the network, or even to your miner.  Only if the miner submits a share that solves a block will you receive anything for your work.

Did you even look at the pull request?  It's clearly cgminer updates from Canaan, and it clearly describes changes for the Avalon 7.

I'd say it is a very clear reference to Avalon and their new hardware.

When solo mining diff means absolutely nothing.  You either submit a share that solves a block, or you do not.  The only reason diff even exists is for your gratification.  It allows you to visually see that your miner is actually doing something.  As a human, what makes you think something is working properly... this:

or a completely blank screen?

As a lifelong Red Sox fan, I know how it feels to finally see the curse lifted.  Seems Theo Epstein really is the draught buster!

Congrats to the Cubs on not only winning, but doing so in such dramatic fashion .

Nice promo.  Hopefully it attracts a few miners your way.

Because you're so new, I suggest you put the bonus funds into an escrow using one of the trusted members here.  At the very least, put the 1BTC into an address and publicly post that address here so people can see that the bonus fund actually exists.

People have been scammed and don't trust easily

Thanks, kano.  I wasn't aware that the standard was 10A for 240V.  Typically here it's 15A on our 120V residential circuits.  Not sure the "standard" here for the higher voltage since most of the time the 240V is used for electric stoves, dryers, HVAC systems, etc.  Usually they're 20A - 50A (at least they are in my breaker box ).

Songminer - make sure you've got enough available power to handle the increased draw from the newly installed 220V circuits.  It can make a difference if you're close to maxing out.  Not sure if you've got 100A or 200A (or other) at home.  Unlike other things in your house (like the aforementioned dryer, stove, HVAC), your miners are ALWAYS drawing the power.  100% load, 100% of the time.

It certainly looks like a good setup.  HP server PSU at the core... 2450W... 10 PCI-e...

Congrats on the 220V install!  Are the plugs going to be each on a separate circuit?  Make sure you've got enough amps .  Figure 1400W for an S9.  A 220V/20A breaker will give you ~3520 usable watts.

I still see it...

Go to Preferences -> Wallet.  Check the "coin control" option.  Restart.

It sounds like you're looking for a remote system you can access from elsewhere.  You can either have dedicated hardware, or you can use a VPS.  A VPS provider that directly takes BTC is vultr.com.

A man is traveling for work and stops into a local bar one evening.  As he walks in he notices there's a live horse on the stage and a jar of money on the end of the bar.  Curious, the man asks the bartender, "What's the deal with the horse and the jar of money?"

The bartender replies, "It's simple.  You drop a dollar into the jar and try to make the horse laugh.  If the horse laughs, you keep the jar of money."

The guy looks at the bartender, shrugs and has a drink.

When he finishes his drink, he drops a buck into the jar, walks up to the horse and whispers something into its ear.  The horse starts laughing uncontrollably, so the man walks back to the bar.  The bartender is obviously dumbfounded, but hands the guy the jar of cash.  The man thanks him, drops a nice tip and leaves.

Several months later the same man is back in town on business.  After a day of meetings he heads back to the same bar and sees the same situation: a horse on stage, and a jar of cash on the bar.

The bartender sees the guy and tells him, "This time, if you can make my horse cry, the jar of cash is yours."

The man sits down and has a drink.  When he's finished, he drops a dollar into the jar and heads up to the stage.  He stands right in front of the horse.  Seconds later, the horse is crying its eyes out.

Like the time before, the man heads back to the bar.  The bartender is truly dumbstruck and asks the man, "I have to know!  Last time you were here, you made my horse laugh.  This time you made him cry.  What did you do?"

Grabbing the jar of cash and dropping a tip on the bar the man says, "Last time I told him my dick was bigger than his.  This time I showed him."

It's the beauty of free will and free thinking.  Anyone can postulate whatever they want.  Then, they can provide whatever evidence they find to support their claims.  Others, who do not believe the hypothesis, can provide evidence that counters the claims.

It's how discoveries and progress are made.  Just think where we'd be right now if nobody bothered to postulate, experiment, refine and build.  Sure would be tough to communicate through this forum were it not for the pioneers who dared to take the risks.

Flat earth... conspiracy theory at its finest... at least it's amusing

You want numbers, that's fine.  However, any numbers that can be provided are based upon conditions right now and are subject to change.  Let's assume that you've got a mining farm setup with 100 batch 19 S9s.  That would give you about 1.35PH/s of mining power.  As of this very moment, that kind of hashing power would expect to make about $940 a day.

Now consider all the other costs associated with that.  Let's say for the sake of argument that you've got really decent electric rates at $0.04 all in.  So, those S9s would cost you $139.71 a day to run.

Wow, sounds great, right?  You're making just about $800 a day in profit!

Sure, but that number is very fluid.  Bitcoin difficulty goes up?  Your profits go down.  Bitcoin price goes down?  Your profits do, too.

Let's throw another couple variables into the mix.  Let's assume that BTC remains steady at $704 per coin.  Let's also assume the network grows 5% per difficulty period and you're mining on a pool with a 0.5% fee.  Uh-oh... you're never going to pay off those S9s.  After a year and a half you're still about 16BTC in the hole and that hardware isn't earning enough to continue to run.  Maybe you sell it all off and cover the costs.  Maybe you don't.

As I wrote, mining isn't a get rich quick scheme at all.  It's a very complicated and challenging market with ever changing conditions.  It's exceptionally risky to get into, and tough to profit from once you do.

Other than the credit card payment, isn't this exactly mining rig rentals' business model?  Hardware owner sets price for control of his rig and duration of contracts.  Person interested, pays X coin for Y time and gains full control of that rig, pointing it wherever he wishes.

LOL!  The nerve of some people.  Please feel free to smite the heathen.

Good luck on your friend quest

So many things wrong here...

1) The bible didn't say anything.  It's a book.  It contains written words.
2) There is no book of "2perter" in the bible.
3) You actually have the audacity to put "i am god" in your profile picture/text.  I'm certain that any god would be proficient in all languages and know proper grammatical structure including punctuation, capitalization, spelling and form.

Opening a mining farm requires a considerable amount of capital up front.  Not only do you need the hardware, but you also need a space to run it.  You need enough power at a very reasonable cost to drive it.  You need cooling, cabling, shelves, switches, routers, etc.  You also need people... electricians to wire things, HVAC to cool things, contractors to build things...

Mining isn't a "get rich quick" scheme.  It is a game of margins, especially when you're dealing with scaling to a "farm".  The hobbyist miner (i.e. someone who's got a few pieces of hardware around the house or in the garage/basement) might be able to offset some of the costs a little easier.  For example, using the heat produced by the miners to supplement their winter heating costs.  It's a heck of a lot easier to swallow losses when all you've dropped is a couple thousand bucks.

According to mmpool, there is no merge mining currently.  NMC is paid out based upon pool reserves - not minting new NMC blocks.

Unless that's been updated, and I missed the post... will let mmpool provide the corrections if I'm wrong
