just put my old sp10's on here to see what I get lol. 2 of the hash boards on the S7 smoked last time I tried to fire it up so am contacting seller...wish me luck with that

what asics are you running Kano?

Ah OK, not a 'setup' problem, sounds like something a lot worse unfortunately

[kano]

what asics are you running Kano?

I have 2 Canaan Avalon A7s
One of the original 6THs ones (721) and one of the newer 8THs ones (741)
They show on the website for everyone to see under Workers->K.Workers and Workers->K.Graph
i.e. that's my Workers

The graphs show:
I usually mine about 16-18 hours a day, but also often all weekend.
Every so often other people point miners at my account and I get a spike of extra hash rate also
(like it shows about a week ago on the graph)

[flminer]

the difficulty rate for my workers is at 0. What would you recommend that be set at?

[flminer]

have been looking at Canaan also. They seem to have less problems and thus more reliable than bitmain.

[kano]

the difficulty rate for my workers is at 0. What would you recommend that be set at?

Unless the miner has bugs with difficulty settings (some older Bitmain miners did) then it's best to just leave it alone.
The pool will adjust the difficulty to get around 18 shares per minute.
The difficulty itself has no expected effect on earnings, the only expected effect is on variance.

So, e.g. if you set it to 1,000,000 you'd send less shares and the shares would be a lot higher difficulty, but would average out to being the same total difficulty. But due to being higher, there would be more variance in when you find shares.

[flminer]

found my answer about the difficulty setting.

[flminer]

was looking around pool site when you posted that

Hello Kano...Thanks for the quick reply. Looks like Ive found a home for my miners. A few of us here in Las Vegas decided to start a small set up and see how it goes. We all realize its a long term investment thing and understand that it may be too hard to mine from a basement... We have resources to add more Hash Power if need be... Problem I see will be during summer here in Las Vegas...but plan on using dryer ducting to route hot air directly outside. Will be registering new workers ASAP we have 2 S9 units that are coming on the March 7th Batch...They say 14.5 TH/s   we shall see. May have more questions in future but I am a quick learner... Instead of putting my money in slot machines I put it into Bitcoin atm machines and buy Bitcoin, winner every time!

Welcome! Just some unsolicited suggestions on the dryer ducting... I'm currently testing a setup in that way with (3) Avalon 741 miners, each with a 3d-printed 120mm fan to 4" dryer duct adapter and semi-rigid ducting. After lots of reconfiguration, I have them at stable temps in a 4" => 6" (6x8 wye) => 8" (8x10 wye) => 10" (trunk) running directly to a 10" wall cap to send the hot air right outside. Also helps to reduce some of the fan noise in my "semi-commercial" datacenter room. The most critical tips I can give are (1) put the miners as close to your exit wall as possible to reduce/eliminate any angles, especially 90deg ones, in the ducts. If at all possible, just give them their own exit vent. (2) it's critical (for the Avalon or the S9's) to keep room/inlet temps below about 28-30C and make sure you have fresh air coming in somehow (inlet vent/AC/etc.) because of the negative air pressure (3) give these things plenty of airflow. 10" duct is already pushing the limits of my three miners in terms of restricting airflow.... my HVAC guy was blown away (pun intended) when I told him these "computer fans" can move 250CFM per fan at top speed. A better solution if you have the space would be a hot/cold channel... you could host a lot more miners in that configuration and just have a big fan at the end of the hot channel sending it outside or feeding back into an AC unit. Good luck! Curious to hear what you come up with in the Vegas summer as I'm in the midwest.

Had another short passthru dropout again at 07:24 UTC - this time about 30 (of about 800) users failed over and reconnected.

Alert
I'll do a passthru restart in about 40 mins (08:30 UTC) since I notice there's been some network bug fixes (finally) in ckpool git yesterday that may relate to the failures.
Hopefully it's the passthru that's the cause of the failures and not the pool itself, since I've not fixed the deadlock in the main ckpool code yet so I can't update it past last August yet ... I'm still working on the ckdb blocksummary changes that are taking a little longer than I expected.

This restart should simply be a reconnect for most miners, but for a small percentage it will simply be a failover and fail straight back again.

Anyone mining on a node (NYA, NL, DE, SG or JP) will not be affected at all.
The nodes of course aren't affected by the short passthru dropout either.

Passthru (both) restarted without a hitch.
User and worker counts are back to what they were, so seemed to have most if not all reconnect without failover.
Hash rate is back up to where it was just before I restarted the passthru.

Mine on

been 19 minutes since last block  could we do back to back?


also price is pushing  1150  with diff only at .5%

A nice morning today.

It's good to see our block streak continues!

On the SG node, there was one of those node glitches at 10:07 UTC
Everyone (of the 9 users on the SG node) reconnected immediately, but it was a failover and fail back which takes 5 minutes in cgminer.

Hi all,
I have been calculating how good is all this mining sorcery. I calculated these tables that actually do not help to trust tht mining is a medium/long term profitable activity. I am loosing faith.

In my world of wonderful any net profit below 1€/day/THs is financial madness. I have barely been making this sort of income but I thought that I just had to be patient in order to see some improvement. This ratios (on the table above) however show a dark future especially with the expectected increase of Total hashing power after March and subsequent increase of difficulty.

Please comment any concerns about the point or my thinking with the numbers, but let me highlight that this is NOT a post against how the pool works or if that other pool is better or anything of the sort. be nice.

can not help you since  information needed is not given by you.

Your information  needs to show us what you pay for power.

Here is a clue if you are at 10 USA cents a kwatt  it will be hard for you to make money.

So plain and simple  what does your power cost

12 USA cents?
11 USA cents?
10 USA cents?
 9 USA cents?
 8 USA cents?
 7 USA cents?

higher then 12 cents  you will almost certainly lose
lower then 7 usa cent you should make some money



IF YOUR POWER IS FREE:

The difficulty of finding coin means nothing.
The price of btc means nothing.

BUT if your power costs a lot you are pretty much dead.

To simplify I used to earn 1-1.5 btc per day back in 2012   but coins were 6 dollars and the diff was low .    i had a free power deal and  split the coins with the guy giving me the free power.  we earned around 100 coins each  worth about  800 usd for all 100.

But if the power was full price we would have spent 2000 usd on power.

A couple of mistakes in there

Time isn't (usually) a factor in rewards.
If the pool hash rate halves, then the pool will find half as many blocks, but your reward per block will double.

The factor that is relevant is difficulty.
As difficulty increases, your expected reward decreases in proportion with the difficulty increase.

Also as Phil has said, electricity cost is one of the main big factors in determining your return.
The other main ones are cost of hardware and reliability of hardware.

Aside: Time becomes a factor if we don't find enough blocks per difficulty change, since then more of your rewards are affected by later difficulty changes.
