This is over the 12 months which obviously the difficulty was much less 12 months ago with a lot higher BTC rewards back then (and lower dollars since it was under $3k). Using the spot price of BTC when the reward was earned, I made $1189 in December and am already at $338 this month. As I mentioned, that is the past which has no bearing on the future. I have not had anyone do a detailed review of my numbers and math. If you are interested in confirming both, I am happy to share the details. If you look at the past week CDT of 0.00015486 and quarterly of 0.00012451, the difficulty change has made an obvious net earnings change since it is less than half of the yearly per day average.
Minergain - I'm currently running about 100 S9s, with 10 more coming online Friday morning and 11 Avalons on order. I recently switched from Slushpool to Kano due the fee difference (and discovered a much nicer user community as a bonus). For me, its just business - I will make more at Kano than any place else I've found at an acceptable variance. Kano's example was 7 BTC difference, but does it really matter if its 7 BTC, $5000, or $1000 over a year? Its still more. |

You NEED to use the 208V lines - the AP3++ PSU can not fully power an S9 on 110V. Likely you will see 2 of your hash boards work fine, and the third have errors until you upgrade to that 208V power.

Yes you can, the controller does not know which physical slot a card is in...

Concur. My farm has also been Bitmain based, but I placed my first order for Avalons yesterday. Post like this one go a long way to making me feel like I made the right call - despite the flood of coupons from Bitmain trying to keep us from switching.

I would beware any announcement that happens on April 1st - April Fools Day.

The best way to calculate for me, seems to be to take btc invested to purchase equipment and use that to find your ROI based on total btc. Many miners use btc to buy their equipment so its fairly simple to go back and look at btc bought vs. earned. If you spent .5 btc on equip, when will you reach that to ROI? Its a bit more easy and fair imo, than to use pricing as that fluctuates so much and a hundred dollars last year is a tenth of what it is this year.
I've mine Bitcoin as my primary source of income, transitioning from a hobby to a job back in November. The post above is accurate. However my method just considers all previously spent BTC on equipment as a sunk cost. e.g. I can't undo it, its history. My "Happy Factor" is now simply making enough money per month (as displayed by Awesome Miner under the Coins tab - where electrical cost are subtracted for me) to live on. My "Really Happy Factor" is when I can put a bit of cash away for rainy days and a bit of bitcoin away for replacement equipment. December was a "Stupid Drunk Happy" month <smile>. |

I'm still fond of the thought that the current lows are due to last year's "Bitcoin Millionaires" in the USA discovering they owe a boat load of taxes that they didn't put money away for. As such, they are panic selling their remaining bitcoins to pay those taxes. Time will tell. Filing date is 4/16/18. Lets see what it is shortly thereafter. That said, governments out to suppress Bitcoin as a threat to their fiat currency, despite the recent G20 statements, can have a field day with this news: https://www.theguardian.com/technology/2018/mar/20/child-abuse-imagery-bitcoin-blockchain-illegal-content |

I doubt Theymos would do that.
Try buying a copper membership and then ask him.
In process. Even if he doesn't, supporting this forum is worth that small fee. |

Wondering if its possible to merge profiles?
For personal reasons, I've abandoned my old Sr. Member account (although I still have access) and started using this one.
I would like to have that account disabled and the Activity points merged with this account.
Is that possible?

So in general, we only have to hope for a block found every month and hope for that expected 100% to be hit.
I think that is a bit pessimistic - its more like a block every few days right now. March has found 9, and its only the 20th. |

They won't shutdown until well over 100C - your temps are fine. I think the cutoff is 115C.

Just received my 6 S9s from Bitmain. Now what to do with the 4 I don't have room for?  List them on e-bay or one of the selling threads here. Might as well recover what you can from them. |

It does not matter to electronic hardware if power off is from a front panel button, yanking its power cord, tripped off by a circuit breaker, or a nuclear power plant crashes. To hardware, that power off is same.
Except for methods that cause surges... Letting the power supply drain down is a decent way to prevent that. |

|
|
for anyone placing a large order from Bitmain to the USA, did you need a customs bond?
I used Fed-Ex for a large order (well over $50K) and did not require anything other than registering my name, address, and SSN with Fed-Ex. ok... perhaps my e-mail too. |

Just power down the power supply, either via switch or unplugging it.
|

Your middle board is failing.
Please confirm your running your power supply at 220V, or otherwise explain how you power your miner.
Try downgrading to the April firmware and see if that helps.
Don't worry about blocking out your userid. The worst that can happen with that information is that somebody uses your credentials to mine and donates their hash to you while doing so.

Bitcoin.com pool has ZERO fees and pays highest PPS..(NO VARIANCE means NOT getting fornicated by 6 & 900% blocks and PPLNS EXTORTION ramp up/down bullshit)
Poppycock. Bitcoin.com charges 0% against the reward but keeps most of the fees for themselves. Back when fees were 10% of the block, he was advertising 105% payout - the 100% base plus half the transaction fees. If you look in his terms and conditions, he even calls that out. Last time I read it, it had a clause along the lines of "105% payout so long as transactions fee represent at least 12.5% of the block reward". From their FAQ: BTC: 100%
BCH: 98%
The extra block rewards come from transaction fees. For example, if the block reward bonus is 105%, the 5% comes from transaction fees.
We do change the block reward from time to time based on how much the pool is making in transaction fees. When the pool starts to see more TX fees coming in then we will raise the block reward again. The change is for all miners on the pool. In the past the block reward we give has been as high as 120% So he paid as "high" as 120% of the block reward, presumably back in December when transactions fees were in the high 30% and mid 40% range. e.g. He was making 10-20% on every block found back then. Not zero. |

Also, you might want to pay attention to the fact that the length of time for them to sell a batch increased a LOT when they moved to the "require payment in BCH", even though Bitcoin price was still rising at the time and demand was still INCREASING.
Instead of "sold out in a few minutes with massive website clog delaying the sales" they went to "needed a few days, then needed weeks" to sell out a batch over the next 2-3 batches after that - DESPITE a still huge demand level.
Not quite true. I bought my 14TH units on 9/27/17 and believe they were the last of the BTC accepted orders. Within days of me placing that order they had switched to BCH. So all of the 2 minute sell-out actions that happened in December and January were under the BCH flag. I know it has cost them a few sales... I was about to buy (12) more a couple of weeks ago when I found myself 0.25 BCH short. By the time ShapeShift converted some BTC for me, my order had timed out. By the time, a few days later, when I got the associated coupon situation under control, BCH had dropped so far it didn't make sense to buy. |

In my opinion, more or less in order:
1) Lowest fees - currently believe that is Kano.is at 0.9% with transaction sharing
1a) Shares transaction fees - back in December, fees represented close to 40% of the per-block earnings at one point
1b) Any pool that does NOT share transaction fees should be rejected from consideration (which, unfortunately, is most, if not all, Chinese based pools)
2) Reasonable variance - you need to get paid often enough to be happy. This is a tough one. Comparing two pools that pass rule #1:
Slushpool - finds a dozen or so coins a day
Kano - finds a coin every few days
.
.
.
solo - only an option if you have several thousand miners or are good with getting a paycheck once a year or so or maybe never.
Variance is the close cousin to "luck". The luckier a pool is, the more blocks it finds relative to its hashing speed, and the less variance it will have. But its not a real thing! "luck" could change any microsecond.
"luck" is just mathematical statistics - over a long enough time period, all pools will average out to 100% luck.
You need to understand variance: A big pool finds more blocks, but distributes the earnings out to more miners. A small pool is just the reverse: it finds fewer blocks, but pays those earnings to fewer people. Over the long run, rule #1, well, rules.
3) Wind-up/Wind-down time - most pools use some leveling algorithm. Using the two above examples:
Slushpool - about 4 hours
Kano - about 12 days
4) User Interface. Slushpool wins hands down over Kano - but you pay over 2X in fees to have that privilege. That doesn't matter much if you have a few miners. If you have hundreds, the difference can be thousands of dollars a year.
Notes:
A) In the long run #2 & #3 really don't matter much. Both pools show your hashing rate in minutes, payouts just lag on Kano compared to Slushpool, but would continue longer if you changed in the future
B) Bigger is not better. Sure Antpool is #1 in size, in no small part to Bitmain using their own pool (no fees for them!). Your profit will be determined mostly by rule #1 - lower fees mean more profit.
C) More, smaller, pools is healthier for the blockchain. If you can live with the variance, support the pool with the longest average payout you are happy with.
D) For pools with long ramp up times that are relatively small, like Kano, you MIGHT suffer due to difficulty changes while you ramp up. For smaller pools, make sure you understand what happens to your efforts (based on their scoring system) when a difficulty change occurs.
Personally, as I thought this over, I decided to switch my 1.3PH from Slushpool to Kano.

Yeah... your miner is using DHCP and changed its address...
