TL;DR Coinshift (http://coinshift.com/) is a new kind of scrypt multipool that isn't so damaging to the ecosystem. Come mine with us!

The Problem
A typical profit-switching mining pool diverts all of its hashing power to whichever coin is most profitable at the moment. When that profitability calculation changes, even if another coin is only slightly more profitable, the pool will abruptly switch its hashing power to the next coin.

This is bad for the alt coin community for a few reasons. It causes huge spikes in the network hash rate for the top coins, causing waves of blocks being generated too quickly with few meaningful transactions in each. The large sums of coins getting dumped onto the exchanges all at once causes huge drops and overall volatility in the coin price. Finally, once the dump occurs and the pool has moved on to pillage a new coin, the previous coin is left stranded with an artificially high difficulty and slower than average block time, which delays transactions until enough blocks generated to readjust the difficulty.

The problem is one of misaligned incentives -- the incentive to mine on destructive profit-switching pools is too great. Coinshift's mission is simple: find a more sustainable way to mine altcoins profitably.


The Solution
Coinshift’s algorithm ranks all the alt coins who are more profitable to mine than Litecoin, and distributes its hash rate across them with a strong bias towards the more profitable coins. As the coins profitability changes, the algorithm shifts some of its hashrate over to the more profitable coins.

This is great for the ecosystem because it helps miners follow changes in profitability without causing them. At the beginning, our allocations will look spiky like switching pools. Over time and as more miners choose Coinshift, our hash allocations will settle closer to equilibrium and help to smooth out hashrate spikes.


Basic Pool Info
* Pool fee will be 2%.
* We pay out every day if your balance is >0.001, so you don't need to trust us with holding your coins.
* Stratum servers in us-west, us-east, and eu-west, and asia-pacific (Tokyo)

Transparency
Our goal is to be as transparent as possible without undermining the security or profitability of the pool. To that end, we're sharing quite a bit on our stats page (http://coinshift.com/stats/), including BTC/Mh/day. We're collecting a lot of interesting data, so we'll continue to share as much as we can.

API
We've got APIs for pool performance, performance history, and account history here: http://coinshift.com/api/

Questions?
We'd be happy to answer them here, or on Twitter (http://twitter.com/Coinshift)

3.3 ~ 3.4 % of fee ? WOW

Thanks for the feedback. Months ago we started this project, Middlecoin was more or less the only game in town. As a result, we designed our fee structure to match theirs.

During those months of work the competitive landscape has changed -- so it makes sense to re-evaluate the fee structure. We're going to reduce the base fee to 2% and absorb the trading and tx fees so we've updated our site to reflect that. Also, the fee is 0% while we're in beta!

You've got my hashes!

Looking forward to seeing this pool grow - you've got the right mindset and finally created a pool that can help level out the ecosystem.  The big shift to multipools has very much negatively affected the landscape of the alts and it's only going to get worse.

[EDIT] For the record - 0% intro and a 2% is more than reasonable - especially considering the server costs these days. 

What time are the payouts each day?

   I cant find on the site the Bitcoins per MH/s: daily profit estimate.

Bump. Nice job finding that Litecoin block.

Definitely following this pool with great interest. With the failure of so many recently-launched coins, coupled with the fact that renting out rigs is more work for very little additional profit, I'm back to looking for a good Multi-pool. I'll throw around 10 MH on this one and see how it goes :]

Do you have statistics on current payout per MH and past history? Couldnt find anything

I'm testing this pool out now. What DDOS measures do you have in place?

I've used middlecoin, wafflepool, scyptguild, trademybit, and poolwarz so far. I like this so far.

100% accept rate and ~25ms ping is good.

On the Stats & Graphs page, I'm terrible with color coding so I'm wondering if you plan on implementing something similar to http://poolpicker.eu/?

looks interesting. i'll give it a try

"We strive for transparency, so we make it a priority to share as much information as we can."

Will you also have a page on block info?

Past 300MH/s just after 2 days; nice.

Nice idea,

I am getting around 11% reject rate, why is that high?

Also:
Since the pool is using Vardiff, it is a nice idea if i can see my miner's current diff on my stat page.

Any stats on BTC/Mh/day?

Profit yesterday for me was 0.01186 BTC/MH/Day = 171% LTC profitability.

that is amazing compared to all other pools right now...

Pointed 5Mh/s to you, make us proud.

You've got my attention. Will switch to you soon once my scrypt ASIC miners arrive.

As a precaution, be prepared if the pool increases 20x overnight ;)

Could you please add a total balance (confirmed+estimated) line.

Thanks.

giving you a try, have added 3 mhs to your pool :)

^ agree, total balance would be good!

Absolutely.


Yikes!

Do you have plans to implement some of the suggestion on the first page such as BTC/MH/Day, LTC Profitability %, interactive graph, block info?

I like the profit-shifting idea.

Pointing 4 rigs your way now (4.5M, 2.2M, 1M and 450K) for a few hours. Let's see how it goes!

Are you guys having some issues with scaling? I "should" have an average of 23MH on the site right now, however, the past 6 hours or so I'm averaging around 17MH. Last night it was fine, however, right now I'm losing like 25% of my hashing power.

Another 2.75Mh coming your way

I pointed 60% of my hashing power here. We'll see.

I really like the idea..
2.5Mh pointing to this pool

Pointed 4 Mh/s your way  ;)

pointed 8Mh/s now to test

I have ~25Mh/s again if my test are good

I like the idea. I don't have much so i'm going to contribute with what I have: 0.75 mhs.
Is there any way to estimate profits? btc/mhs/day?

Would be nice to see estimated profits. Also it would be nice to see an estimate for unconfirmed blocks (I am assuming these are not included on the user stats page).

Yeah, not sure if profit will be where I expect it to be... after 4 hours mining with ~8Mhs I have only 0.0013 exchanged and 0.0018 unexchanged, so I should expect about 0.0186BTC/day with 8MH/s? That's only 0.0023BTC/MH/Day  ???

BTW, the reject rate across 4 rigs is about 3%, which is acceptable.

Perhaps, posting the profitability will improve the transparency?

Bah, lightweight:

Did I miss instructions for individual workers?

what time are payouts done (in EST)

1BTCADDRESS.worker_name for username

Individual workers are fine for me. They are on the stats page. But not really useful to show them on a same small graph. Needs a better graph with useful guide lines.

Balance is very low for me too. Confirmed and estimated together is 1/5 what is should be.

No need for separate workers. Well it is still beta but just looking at my CGMiner screen shows me high diff as well for a short time, just before a disconnect.

Thank-you kindly, that got rid of the 54K pool difficulty. Now seeing more sane values.

Sorry guys. In the afternoon as we approached 500MH we started to have some orphaning issues. If you started mining < 6 hours ago then you got the short end of that stick. It's stable now, but we've removed the mining instructions from the site until we can put in a scalable fix.

Overall BTC/MH/24h was .005 which wasn't all that bad considering the numbers I'm seeing on poolpicker.eu, but still very disappointing. We're working on it 24/7. I've barely slept in days!

Thanks everyone for risking your hashes with us. We're determined to make it worth while.

Edit: also the high VARDIFF targets will get rolled back once we sort out the performance problems. 54k diff --- how many cards do you have in that box!?

How many people are in your team?

6 x HD7950 in that rig, but 10 rigs total on your pool. Separate workers seems to have resolved it as the highest diff I have across the 10 rigs now is 3.66K.

That's all good, but if you really want to provide full transparency, as you claim, you need to have BTC/MH/day published. Otherwise, this could be one of those "good idea but poorly executed".

BTW, I scaled down from ~8MH/s to 1MH/s for now...

Agreed 100% I'm still following this pool and I'm excited to see where it goes, however, $25 in profit on 23MH over 24 hrs doesn't even put food on the table haha. Definitely dropping back a bit until you guys get it figured out.

After mine 6 hours I've got a % of 0,00589BTC/MH day

Assign less hashrate to those small coins, maybe it is better if u have a history of mined coin and how much hashrate assigned to them and what was its result.

Also please add more profitable coins. There are numerous coins pool is not mining.

Any update guys??

http://coinshift.com/static/logo-med.png

Coinshift added (http://vardiff.com/pool/coinshift-com/) to mining pools database
Good luck, miners

lots of stats and graphs - great. but is it possible to show us the real profit graph for few past days or anything so we could easily see the % of profit over straight ltc mining.

no payout today?  edit: Just got it  :-)

We just posted a "thank you" 0.25 BTC bonus block to the pool.

We wanted to thank everyone that risked their hashes on our idea. You guys stuck with us when the going was tough and we can't thank you enough for it. With your help we think we have a chance to make a difference in the altcoin ecosystem.

We've fixed all the scaling issues we had early on and we think we're about on-par with the other multi pools as profitability (we'll see over the next few days). We still have a lot of ideas on how to improve profitability, too. We've added the BTC/Mh/day graph to the site, and we've even added some apis (http://coinshift.com/api/) for those who want to graph it themselves. (Disclosure: the bonus block did affect the profitability graph)

We'll be posting another .25 BTC block tomorrow afternoon for the newcomers and those that tried us but had to switch away due to low profitability. Swing some hashes our way if you think our cause is worthy. We'll try to not let you down.

Thanks, from Coinshift

Do you have plan on adding more coins?

Absolutely. We'll be adding a few more coins this week.

Bonus block is going out in 3 hours, make sure you're mining for at least an hour before!

ive been sticking around for the past 5-6 days. ive never used a profit switching pool (mainly because i don't support their toxicity) so i can't compare profits. overall i think payouts are low, although altcoins have been in a rough spot lately... but i genuinely believe we will iron out our issues and support your cause. keep up the good work. my 2.5 mh/s is here to stay.

Been mining here for a few days now with 510kH/s, but I'm getting a very high difficulty since the past two days. My hash rate graph jumps up and down from 200 to 1000kH/s. Any plans to implement manual diff adjustment? (like -u BTCaddress.worker+difficulty as on P2Pool?)

What's your address? I'll check on yours specifically.
Ideally you wouldn't have to do anything manually and vardiff would take care of everything. Our VARDIFF target is 1 share every 25 seconds, which over the course of the day should result in very low variance (60*60*24/25 = 3456 shares per day).

If yours variance is bad, we could consider lowering the vardiff target or adding manual difficulty adjustment.

Some updates:

We resolved all the problems with rejects earlier this week. Reject rates have been very low now for a few days.

We added two more coins today, FLAP and HNK. We'll be adding more this week.

Our main focus right now is keeping profitability up, but the altcoin market is really sagging. Profit-switching is really killing the market, but we don't think we were too late. Come join us and let's balance out the hashrate!

when using stratum-mining-proxy, all my BTC addresses result in "Invalid payout address".
i use mining_proxy.py with options "-cu <btcaddress> -cp x"

edit:
sirs, my apologies;  it turns out that pooler's version of stratum-mining-proxy fails, but the slush's does not.
case closed.

Can you reply with or PM me the address you're trying with?

Thanks for looking into this. I'm seeing more like 1 share per 1-2 minutes. I've sent you a PM with my mining address.

We're up on http://poolpicker.eu/ !

You're right, you're submitting once per 60 seconds. We'll deploy an update today/tonight that will fix that.

Thanks for the report!

Profitability just spiked! Did we score a few DOGE blocks?

Yep we hit a DOGE block!

We pushed an update last night that resolved the issue that justme27 reported. If you got a string of quick shares and VARDIFF pushed you up a tier, it would never let you back down. We can also consider lowering the target share time to 20 if people still think that's a problem.

Please keep up the feedback, it really helps us improve the pool!

With last night's update we also added some more secret sauce that should improve profitability. We'll also be adding two more coins later today.

Happy mining!

Keep up the good job guys.

indeed and mh/s on your website dosen't match poolpicker.

It feels fishy... Is profitability really at 0.00722/BTC per MH/s while Clever's is at 0.00590?

I'm wondering too. Admin announced that they had some secret improvements last night.

It went up right after they hit a Doge block.

I see it's been fixed, thanks! Share rate is steady now and the hash rate graph starts to make some sense :)



My counter is at .0032BTC confirmed since the last payout (< 20h ago), with about 500KH/s. So that seems pretty accurate.

if they got that result with just a block of doge, what will happen with a lot of doge/ltc blocks ;)

seems really interesting

We did hit a very lucky doge block without investing much hashrate towards it last night, so the performance will appear elevated until that passes the 24 hour threshold. The graph and that number are real, but remember that the graph shows performance over the *last* 24 hours and isn't a predictor for the next 24 hours (I expect we'll continue to perform on par with the other pools).

I'm sure someone who's been mining over the last 24 hours can confirm. Also you can see the block exchange in the detailed stats view (http://coinshift.com/stats/#more). We try to be transparent about these things.

In other news, we just added an API for retrieving individual user stats: http://coinshift.com/api/
We hope someone makes some cool stuff with that! Forum sigs, anyone?

any one else not really seeing the similar performance #s to the ones listed for trailing 24 hours?

i'm willing to give this pool some more time, but as of now (~17.5 hours in) I'm only getting about .0057/.0058 btc/mhash/day across 2 different rigs and not the roughly .007 as listed on the stats page.  I included payouts, confirmed exchanged and estimated unexchanged in my calculations

I'll check back in a few hours once my full day comes around.  I really want to believe in this pool since it is doing what a lot of the other pools should have been doing in the first place.

Would it be possible to represent profitability with additional details beyond trailing 24 hours only?  Maybe break it down hourly for the past N hours or something?  Does the  API support that time granularity or is it only on 24 hr ranges?

I'm mining for 14.5 hours (Since last night) yielded me about 0.00432, thats about 0.00719 in calculation.

Lets see what will happen in the coming 24hours

figured I would chime back in.

reran the #s at 24 hours and i ended up with .00610 btc/mhash/day ... which was exactly what the stats page was listing at the time.

guess i just hopped on at the wrong time and missed the higher earning hours that drove the trailing 24 hrs # so high.

either way, i'll leave my rigs here for a bit and see how it goes in a few days.

Thanks for the update, boxofspuds. Sorry you missed out on that awesome Doge block  :-\

We just added 2 more coins: Feathercoin (FTC) and Smartcoin (SMC). More to come!

We also looked in to taking advantage of the ghash.io promotion. We've written a proxy client to take advantage of it, but they've already reduced the rewards to 1.25. Looks like Waffle may have diverted some hashes to it, which may mean we'll see an improvement in profitability on the other altcoins. We'll keep an eye on it, let us know if you have any preferences.

please add earthcoin & flappycoin ASAP

BTW Could you please add an API to get current hash distribution of the pool?

We've got Flappycoin! Added it a couple days ago. Will look in to Earthcoin.

API info: http://coinshift.com/api/

Edit: misunderstood. Yeah we can add an API for that, will get back to you.

We lowered the threshold for DOGE to activate to ~400MH. So far, so good! Variance will be higher this way, but DOGE is currently by far the most profitable coin. If we have a long slow period we'll toss some of our own coins in to supplement. We'd like to grow past 1.5 GH so that our variance will become manageable while mining on the bigger coins.

Keep on hashin'!

Yeah, saw that.
I Suggest please add Earthcoin & Anoncoin. These are very profitable time to time and other pools take advantage of them.

Bad thing is that admin of coinshift is online for about 2hours every day. He/She is not around more time. We put a msg and we get a reply on the next day. i dont like this.

I have some minor bugs/annoyances/questions:

- The "Current Allocation" circle doesn't seem to correspond with the graph right next to it. Even worse, the circle shows something entirely different when you hit F5 a few times, but the graph doesn't change accordingly. Example: https://i.imgur.com/fB7ngve.png
- The choice of colours on the coin graphs is pretty bad. Many coins have the same or very similar colours, making it hard to tell which is which. The colouring is also not consistent, different colours are used on each chart.
- Why is the BTC/MHs/day figure on poolpicker.eu so different from what's displayed on the site itself?
- Why does payout happen approx. every 25h now instead of 24h?
- Why are some coins exchanged pretty much instantly (DOGE) while others take all day? (FLAP)

And a little feature request: Would it be possible to show which coins an individual miner has mined on the "Account Info" page?


All pretty minor issues, but still I feel it's worth reporting/asking about :)

That one surprises me! Most of the time we're not spending in the forum we're working on improvements on the pool. But, we'll make more of an effort to reply on the forums here. You can also follow us on Twitter (http://twitter.com/coinshift/) as we post smaller updates there sometimes.

These are all great suggestions (many of which we're aware of). Currently we're focusing primarily on the behind-the-scenes stuff (focusing on profitability, new coins, server stability, etc). Once we're pretty confident all that stuff is sorted out, we'll put some more work on the UI of the site.
* The allocation graph is correct, but the "current allocation" pie chart is really buggy. I almost want to take that out until we have time to fix it
* The colors will get fixed when we switch to a different graphing library. We're going to pick on that allows you to mouse over to see exact values
* Poolpicker grabs the data from our api (http://coinshift.com/graph/api/v1/performance/30d). He only samples one point off the graph, I think.
* We're going to switch payout to another time of day so that we can make it more consistent. Unfortunately Cryptsy (and other exchanges) won't let us auto-withdraw at the moment.
* A few coins (FLAP, LEAF, LOT) are pretty hard to exchange quickly because the value per coin is <10 satoshi. If one of those coins isn't selling fast, we can't knock down the price because going from 6->5 or 3->2 satoshi per coin would be a bit hit.

We can definitely add coin values to the miner page!

two question:

1) could u add an API to get current hash distribution of the pool?

2) Do you have any plan on adding more coins?

1) We're considering that, there are definitely concerns as to whether that could create competition problems. What would you think that would be useful for?

2) We'll be adding 2-4 more coins this week. I know you're interested in EarthCoin! If anyone else has suggestions we'd love to hear them!

I would suggest not showing which coins we are mining at all, even in graph form. Let the other pools figure things out on their own.
I've switched completely to this pool. I rely like the profit switching concept, and it seems to be working out just fine.

1) I was thinking about making a real-time stat for me and other users. maybe you can provide this api with some delay, for example hashrate distribution of last minute, not current minute.

2) My suggestion list is: Anoncoin, Earthcoin, Mooncoin, Fastcoin, Reddcoin, Netcoin, Nyancoin, Infinitecoin. Please add these 8 coin to increase pool profitability even more than any other pool.

Pointed one of cards here, will switch the other after I get paid from other pool.  I like the idea.

Any plans on making accounts and ability to select which coins to not auto-trade?

Just wanted to thank you guys for making a pool I don't feel guilty for mining at.

Would it be for a future feature being not trading a certain coin? Like if I want to bank DOGE?

Thanks guys!

No plans for that at this time. We chose early on to not require signup and instead payout automatically to the BTC address that you mine with. That choice is unfortunately incompatible with choosing to keep certain coins.

There is very little lost in the trading fees, though. You should be able to convert the BTC you earn back in to any currency you'd like fairly efficiently!

Congrats on getting 1GH/s :)

Right now the profit is flatlining though... I see the coins disappearing from the unexchanged graph but they don't reappear on the exchanged coins graph. What's up with that?

Pointed my second card to your server today!  Was previously mining at middlecoin and for whatever reason I get at least 3x the amount of shares with your pool than I did with middlecoin.   So far im quite happy and plan to continue mining your pool.

If i have profits less than 0.001, when I'm going to receive my payout?

Thanks!

What is the plan with DOGE now that they hammer difficulty as soon as a pool points at them?

I see that it's coinshift is about 86% DOGE right now.

That was from the unfortunate crash of Flappycoin (which as of now appears dead). Most of our unexchanged balance at the time was in Flappycoin, which is hard to sell effectively because it's value was only 2 satoshi and the exchanges don't have sub-satoshi pricing. The price eventually dropped to 0.00000001, so we sold most of it for half as much as we were showing in the unexchanged graph. As of now there are only sell orders for Flappycoin in the exchanges, no buyers.

Ideally we should have stopped mining Flappycoin earlier since it wasn't exchanging well. We've suspended both FLAP and LEAF because their prices are too low to exchange reliably.

We're learning, and we'll continue to improve our autotrading intelligence.

What happened to FlappyCoin? Did something drastic cause it to crash? Can't you exchange Flappy to LTC then to BTC?

That's what's great about a shifting algorithm. As the difficulty rises, we can gradually pull back from a coin and place those hashes on others, as long as there are other coins that are more profitable to mine than LTC. With enough hashrate and the right algorithm, we could even settle into a hashrate equilibrium, where we see an end to these massive spikes.

Our goal is to balance two competing factors: sustainability and profitability. The basic concept is: when one coin is more profitable than another, how much more hashrate do you give it? Right now we've got our shifting algorithm in "aggressive" mode, meaning it's more concerned about profitability. That helps us ensure that we can compete with other pools and attract miners to join us in our quest. Over time and as we have a more significant hashrate, our plan is to to see how much we can turn the dial back to sustainability without sacrificing much profitability. That will be better for the whole ecosystem and should actually improve everyone's payouts.

The difficulty swings from multipools was too much for it, I think. It's being delisted from some exchanges. Some people are still holding out hope!
http://www.reddit.com/r/flappycoin/
https://bitcointalk.org/index.php?topic=464743.3480

I'm sending 30Mhs to CoinShift, and it was reporting a lower hashrate but that was ok (~27Mhs). Now, for a few hours, it's reporting less than 20Mhs (including rejected hashrate).
Am I the only one to experiment this ?

I have 1.5Mhs pointed to coinshift and now in the pool stats it seems to be 1Mhs...

I also have problems with which you're saying... I think that there's a problem in the stats and payment... I don't receive anything (yet) and the pool says that is paying 0.00749 BTC/Mhs/day so it's obvious that i least i need to have ~0.0001 lol

Im on a .5/m hasher but have received payout the last two days.  I have noticed the  hashrate stats are incorrect, sometimes  higher and sometimes lower.

I like this pool the most out of the top five at the moment. Fast payments and a cool concept of shifting load instead of going 100% on one poor coin.

The thing I noticed so far is that multiple worker configs have a problem. If you set up youraddress.worker1 + youraddress.worker2 etc., the combined hash rate is always lower than what you'd get while not using individual worker addresses. Or that it is just a display glitch on the frontend.

BTW guys, please try to make the line colors in the graphs more static. Not a big issue but they tend to "shift" color on every page reload so far. :)

Does expiry, scan-time, queue have any effect?

Can you PM or post your address so I can look at it? What server are you onWhere are you located?

That makes sense.

What I really am curious about is how you calculate profitability with their instant difficulty shift. As I am sure you know, (this is for the class :P) DOGE now instantly adjusts difficulty in the hopes to cause unsophisticated multipools to hop on, then instantly hop off.

Are you saying that you calculate the profitability for Coinshift after the "expected" difficulty spike before we start mining?

If so, makes total sense. Otherwise I am curious as to how it stays worth mining.

Thanks!

Hehe, yep we're aware of that. It's super annoying, but so far we've been prioritizing backend fixes rather than working on the UI. I promise we'll get around to that very soon.

There may be a quick tweak I can do that will make it better today. But in the longer term we want to switch those graphs to a better graphing lib.

* Can you share your address or link us to your account page? At 0.5MH you will have some variance, so you should be seeing hashrates from 1.0-2.0MH which over the course of the day average out to 1.5

* How long has the 1.5MH been pointed there? Since we're mining a lot of DOGE at the moment which has higher variance, (blocks come every 1-2 hours) you will have to stick with it for at least 24-48 hours to see a fair report

Here you have: http://coinshift.com/account/1FrzQeGqWrKzwLGv9uMPVxbe9DyTs4RNQW

I can't see anything in "Estimated Unexchanged" :(

I'm seeing the same pattern as EricKennedy to say the truth. Hash rates have fallen down for the last 3 hours or so even though worker efficiencies are rock solid here. Not whining but there's something to look at over there guys. Hopefully just a frontend problem.

Edit: Fixed now.

Confirmed.

Also, it seemed to only be on the display. Payout was constant.

Guys, thanks for reporting those issues. We were able to get it fixed -- sounds like two of your have confirmed it's looking good now.

@Eric your hashrate should now be reporting properly again, please let me know if it isn't.

Thanks @coinshift for solving the problems!!

But 1 thing... the Current Performance (trailing 24h) it's 0.00847

Is it correct?
Thx!  :D

Looks like we've had some good luck today  :) DId we find another DOGE block?
Waffle is also up today, but not as much as we are!

Yep, DOGE has been performing quite well for us today!

We deployed a hash allocation algorithm change last night that we hoped would improve profitability. It performed really well overnight -- we'll see over the next 12 hours whether that was luck or a marked improvement.

I'm sending approx 23Mhs to Coinshift, and I'm seeing around 16Mhs, and it's dropping...
When I'm hashing on CleverMining, I see ~22Mhs which is fine.
Eric

Getting lots of 'job not found' on the EU server. Something up?

Pool 0 is Coinshift EU
http://puu.sh/7CckO.png

Somethings up one of my cards has 156stale and 62 on the other, first time its happened since ive been mining here.

some observations after another 24 hrs mining here.  I had moved off to another pool previously, but came back and had a balance of 0, so this is fairly accurate.

right now the api is returning
"value_per_mh_24h": "0.00576"

but my actual calculations for btc/mhash/day is roughly .0064 and .0063 across 2 different rigs

I've also noticed we've been in a decline in profits for a few hours  :'(

In the meantime, I do have one request.  Would it be possible for the api page: http://coinshift.com/api/stats/performance/ to also include total payouts in btc?  I'm not looking for a "for the day" total, I'm just looking for a "since the beginning" or "from this day forward".  Essentially something that will not/never be set back to 0.

I'm writing some scripts to pull out pool vs rig performance, so it would be helpful if there was a way to determine much btc was paid out in total. 
as it stands now, I can tell how much MY last payment(s) were (all time payouts on miner page, payout_sum on api page), but I have no idea how much in total was paid out to the pool.  As far as I can tell the "Current Pool Balance" from the stats Page/value_24h from the api will get zeroed out every time there is a payout.

-spuds

After this night's run, all reportings are ok.
I'll keep you informed if anything happen.
Eric

@coinshift

I think this is something you might want to integrate into the system. It would support the general idea of the pool. Some free profits with merged mining. They don't do exchange and that's where you'd come in with two efficient techniques + auto exchange.

http://manicminer.in/docs/mining

P.S. Check your inbox. Thanks.

Seems like the bottom dropped out of the market after the ASICs were pre-order-able. Ugh.

*edit - Random thought.*

Interesting observation from watching the allocation of hash and profit/MH.

It seems like the coinchoose algorithm is fighting hard to not allocate a lot (80% +) to DOGE, but is finding hard to not do so.

We keep bouncing from a balanced distribution to a all on DOGE to keep the profit levels ok. Almost as if there is a lower limit of "throw the balance out the window" for profit MH/day.

Quick math,

DOGE = 0.00000122 @ 2:57pm PST

Estimated DOGE per MH/day = ~3537

3573 * 0.00000122 =  0.00435906 btc per MH/day

So... hmm.

Guess the market is just shit. lol

Site down??

No but I guess while the system is preparing to send or while sending out payments, the site becomes slow sometimes. That's what I thought it was. It can be a coincidence of course.

put in the url without the www and it should work.

I'm glad you're watching closely, it's definitely fun to follow. The multipools cause this effect. Just look at this graph of the DOGE difficulty, for instance:
http://coinshift.com/graph/coin/difficulty/DOGE

With constant swings of over 50% difficulty, DOGE oscillates from being very profitable to very unprofitable. We have the amazing advantage of being able to fill those troughs with hashes, and start to gradually pull back as it rises above its midpoint, but you're right in that we struggle to find other coins to allocate hashes to. We're not always able to find other coins that are doing better than LTC. That's a fundamental problem with the ecosystem: they've been battling the multipools for months, and they're starting to lose.

We'll be adding a few new coins and retiring some old ones this weekend. We think that should re-invigorate things a bit! Always open to suggestions, but coins that are traded on Cryptsy tend to work the best (both in terms of BTC volume per day, and the ability to auto-trade).

Current candidates are REDD, NET, AUR. We'd like to reintroduce NEC since it seems to be doing well, but we can't seem to peer well with other NEC nodes so we get a lot of orphans. Anyone know of a node list for NEC?

Thanks, that's embarrassing! Fixed.

Updates for today:

We pushed out an update that should improve our hashrate headroom dramatically. If you were previously on the EU server having having issues with not seeing your full hashrate, that should be completely resolved now. Sorry for the inconvenience, and please let us know if you try again and still have issues. We're currently processing ~3,000 shares per minute, and should have no problem scaling up past 50,000+ (fingers crossed).

We restored the EU VARDIFF to the previous target of 1 share / 25 seconds. It had been increased to 1/35 temporarily to reduce strain on the system.

We've also dropped the min VARDIFF target to 64, and it now moves in smaller increments (also 64). That should help us to support those of you with smaller rigs.

Tomorrow we plan on adding the coins we promised for this week, and removing some dead coins. If all goes well on the stability/profitability side, we'll also have some time to put in to the UI and API.

I think the best thing to do is to see what altcoins other multipools are adding into their switcher. For any switching pool to be effective you have to keep ontop of what new promising altcoins are coming out and add them quickly to your switcher list. For example, trademybit.com does a very good job keeping on top of this if you look at their list -- it contains a lot of recently added scrypt coins. ipominer.com is another one.

At the least you should be adding spaincoin and ecc to your list because they're on the profitability train at the moment. My 2 satoshis.

Also, consider adding a multiport for scrypt adaptive-N coins. Once scrypt asic's start coming out, probably several months or sooner from now, there will likely be a migration to asic resistant coins. trademybit is the only pool I'm aware of that currently offers this. None of the other pools like wafflepool, clevermining, middlecoin etc. have this feature.

Hey Coinshift,

Any possibility to add a running total of how much BTC the pool has paid out to the api page http://coinshift.com/api/stats/performance/?
thx

If we just put this picture instead will that be OK?
http://img2.wikia.nocookie.net/__cb20090506185112/uncyclopedia/images/f/fa/Dr_evil_one_million_dollars.jpg

Edit: Just kidding, yes I think we can add that to the API. Will post when it's done :D

We are strongly considering scrypt-n as an option for expansion soon. Stay tuned for news on that, but you should expect more expansion in the scrypt coins first.

We're tracking a lot of altcoins for profitability and we'll be adding a few this weekend. If you have concrete reasoning for a specific coin or two, let us know!
To be frank, the coin must be exchanged on Cryptsy to be worthwhile to mine. Other exchanges just don't have the trade depth or the API to make it worthwhile.

what is the Worker Difficulty?

hashing for 24 hours, average 3.6Mh payout 0.013BTC, sorry leaving, cann't pay my electricity with this profibility

VARDIFF. Min 64. Diff will adjust so that you submit 1 share every 25 seconds

Just checked my stats on Coinshift after 24 hours mining and my confirmed + unconfirmed balance is 20% lower than I would expect with my hashrate from your pool stats.
Is there a time lag on these figures?
I really like the idea of this pool, and don't want to leave but as someone else just posted, at the moment a lot of us are barely covering our electric (or not if my stats are correct) and I will have to reluctantly go back to Clever if this is not sorted, where at least I know I will get what the pool stats  say. :-\

Hmmm, that's very strange. The block payouts are PPLNS, so it would take about an hour to get up to full speed -- however that would only account for ~3% over 24 hours. Please post or PM me your address and the hashrate reported by cgminer so I can look in to it further.

Added 3 new coins today: AUR, KDC, RDD.

These coins have been near the top of the charts for the last few days, so I think they'll do very well. More coming soon.

What happen i cant access coinshift dot com

The site is entirely 404 error pages at the moment...

Interested to see how long this lasts.

Edit: back up... didn't take tooo long.

What about Anoncoin & Earthcoin ?

@coinshift

I've a question:

For example, now that i am writing this post, pool is dedicated 96.5% on AUR and 0.73% on DOGE and remains on others.
Since pool has 2.5GHash, 0.73% will be about 18Mhash. It is obvious that 18Mhash cant find any DOGE block. So i think the pool algorithm should consider coin's difficulty into it's dedication's amount too (i like to call it hashrate efficiency).
It is wiser that pool assign those 18Mhash to RDD or GDC since it can be more efficient on those coins difficulty [OR] assign enough hashrate to DOGE side.

What do you think?

has anyone mining on this pool been affected by the whole client redirect hijacking going through some of the other multipools?

Left for 18 hours and checked again. It is still lower than expected, so I'll keep an eye on it.
My address is18i78kvyuxVrRVufXUTs9qpLbBGmrygqSx.
Hashrate on cg miners for 3 rigs adds up to 10.4 mhz

How many btc a day with 1300 kh/s ( scrypt ) .

Nothing like that for now..
Mining is not affected.
We have trouble on and off accessing the main page however
Still better than having redirect and got your hash stolen.

I have realised I one of the cards has been down on one of my rigs. Think I have sorted it now.
I will stay with you if I possibly can. The way you mine is the future. The old autoswitching pools are damaging the whole cryptocurrency landscape.

I ve been mining for around 8 hours hours and so far the BTC/MHash/Day is ~0.05 not 0.058-0.062+ that is advertised by the website

How would you handle the switch between scrypt-n and scrypt? I am unaware of a way for the client to be aware of the pools change in type. If there is... excited...

Scrypt is Scrypt-N (with N=10), so the stratum protocol would simply need to be extended to allow the server to communicate what Scrypt N value to use when hashing a given block.

Try for longer then 8 hours...  The BTC/MHD published on the site is over the last 24 hours, so it won't be accurate for the last 8 hours.

---

Is CoinShift using some fancy logic to avoid wasting hashing power on Tag?  TAG has some really stupid prevention measures that prevent blocks from occurring 'too' often, based on the time between the last 6 blocks.   So even if you're solving valid blocks, the network will continue to refuse them until that time lock has passed.

---

Any plans to add FlutterCoin (FLT) or SpainCoin (SPA) ?

what happens on the site?

good question, site was runing yesterday

I think it's getting DDOS attacked.

that's alot of attacks today, a big exchange is also getting hit today :

Crypto Rush @TheCryptoRush
We're going into maintenance to attempt to stop this DDoS attack! ETA 30 mins.

Middlecoin also got hit I believe today

Do the mining still working and be accepted during the 404 ?

I should not take the risk mining there right now

Mining is unaffected. The web servers are completely isolated from stratum.

404s are resolved now. Sorry about that.

thanks! keep up the great work guys

Just saw my miner hashing from last 11 hours with no accepted and hence no hash on site. Same happened when wafflepool was atacked hence I shifted here. Not sure what do now. May be need to shift to some unknown small pool for few days till hacking solution is sorted out.

why the profitability is lower than litecoin?? why not pool is mining litecoin now?

I see there is a lot of estimated unexchanged balance since yesterday, about half of total. Is this another dead coin or maybe just unresponsive exchange api?

Front end is occasionally 404-ing again... Mining seems unaffected though.

Why are you hodling all that AUR? Dump quickly before the mega-crash! :o

Down to 0.004BTC/MH/day doesn't look good...

why pool not mining pure ltc right now?

I think earning is stuck for 12 hours now. ALmost like not mining anything What's up coinshift ?

The the AUR is still immature. Multipools keep stranding it at a super high diff for 5-6 hours: https://aur.cryptocoins.at/explorer/chain/auroracoin
We've disabled it for the time being since it's so difficult to exchange.

We skip any coins that we can't expect at least 1 block per 1.5 hours. However, with the market the way it is, we've bumped that to 2 hours so that LTC will activate.

We've been investigating these reports... Were shares showing accepted on the miner? What software and version?

@coinshift

I've a question:

For example, now that i am writing this post, pool is dedicated 96.5% on AUR and 0.73% on DOGE and remains on others.

What do you think?

There's an echo in here.. echo in here..

Last night, I tried to get on this pool and it kept coming up dead on sgminer.  I'll double check my settings but was there an issue last night?  I tried the backup and the regular address. 

That's a common question. Since finding a block is an independent random chance, you shouldn't slice up the hashrate and try to look at pieces independently across small time periods (in this case, the instantaneous DOGE hashrate). Statistically there is no benefit to maintaining some "minimum" instantaneous hashrate on a single coin.

We do manage the pool's "hashrate efficiency", but it matters only in aggregate across all the coins we're mining and across a longer time period. In other words, you should look at the weighted average of the coin difficulties, not any one coin. For example, imagine we had 2000 altcoins, all with the same difficulty as DOGE. We then allocate 0.05% to each. If you look at an individual coin you would think the probability of finding a block would be quite low. However, in aggregate, we'll actually find blocks quite often -- this is because the risk/reward ratio for each unit of hashrate is profitable.

Another way to think about it is thinking of it over a longer timescale. Instantaneously at some points it was .73% DOGE and others it was 80% DOGE, but over the course of the day it averaged out to 700MH/sec.

Whatever you are doing now you're doing it wrong profitability is below ltc and has been so for more than 24  hours.

Been running cgminer and my avg hashing rate is 2.833Mh/s but combined accepted/rejected hashrate per your site seems to be hovering between 2350 and 2500Mh/s.  I'm fairly new to mining but having tried out Middlecoin, Cleverming and WafflePool for a couple days each, they all virtually nailed it.  Any suggestions as to why I'm coming in below and/or what to do about it?

Compare pool reported hashrate to WU, not hashrate.  See if that matches more closely.

What's your address? I'll take a look. If you could post a screenshot of your rig hashrate that would be helpful too.

Nowhere to upload an image to at the moment but a screen copy as of 12:33pm, PST.  I did drop the Intensity down to 18 from 20 and that has seemed to matchup with the site a little better (as well as produce far fewer rejected).

Phzi - Pool hashrate as of this moment is 3091.675 Mh/s.  Website is 2301.8 Kh/s with a rejected of 54.8 Kh/s.

Damn!

Thats a good WUE!

We had some luck with that eh?  ;D  If only it was always like that.

How much longer are we going to sit with this unexchanged balance?

Yep, fair enough. We've been very disappointed with the performance over the last day. We trimmed out some poor performing coins last night and things are much better today. We'll keep you posted.

Now BTC / DAY ?

The AUR is finally mature so it will exchange today.

We're at .00498 right now which is good considering we're above Wafflepool and CleverMining (as of this very moment). I expect we'll get a bit above .005 today.

Your reasoning for not mining LTC when below LTC profitability is sound but those others don't have a clue even when they have the power to mine it. I hope you reach enough hash rate soon. I'd like to suggest that you make the preparations to do what others can't, when the time comes.

Pointed 3.6MH/s your way to see how your pool works out for me.  If it's good over the next 24H, will point the rest of my hash power over.  I like the idea of the pool, it makes sense.

Everything looks OK to me -- perhaps when you checked the site you were on the lower end of the variance. When I checked your hashrate was reported as >2900Kh: http://cl.ly/Uh37

The site currently reports the hashrate as calculated over the last 20 minutes. There is going to be some variance there, which is why you see the graph oscillate between 2300 and 3000. Maybe we need to increase that so it gives you a better picture of your actual hashrate. The problem there is that we don't want it to take a long time for new users to see their hashrate ramp up. There is definitely a way to make it work for both, so we'll work on it.

To double check I calculated your hashrate over the last hour:

I send you PM and tried to contact you via twitter:

Hi-
Why is my unexchanged balance going down but my exchange balance is flat lining?   It rings true in the numbers that are also shown on my stats page as well.

https://i.imgur.com/ikoQaBl.jpg

AUR is currently stuck (very slow blocks) and quickly dropping in value at the same time.

So from what i understand it's better to mine LTC than using this pool, right?

My payout is not coming  >:(

"We _finally_ exchanged the AUR, but for way less than we expected when we mined it. Felt terrible so we doubled it out of our own pockets."


That is really nice of you guys! I didn't see a post about it here, so thought people should know. :D


Two questions:

1 - Will that come in a separate payment or get rolled into our normal ones? It will be hard to tell either way.

2 - Can we add LTC to the rotation? Since we compare against it as a benchmark it would make sense to incorporate it into the algorithm so that in the event alt coins are doing really bad, we can supplement it with LTC. If the Coinshift algorithm is smart enough it should be able to do this and keep things balanced. :)

There aren't enough uptodate scrypt coins on the switcher. Please add a link to this thread on your "about" page. Consider going with a fee of 1.5% instead to give your pool some kind of incentive to mine there. At the moment coinshift is doing substantially worse than clevermining.

Also show the profitability calculations of how coins are being selected. eg. Something like coin profitability vs LTC like your example under "about".

Clevermining reporting .00461 BTC/mh/day on thier website at this very moment.
CoinShift reporting .00496 BTC/mh/day.

I don't see how that means "substantially worse". If anything they are the two closest matched profitability wise and it really comes down to luck and hashrate and personal preference between the two. I see no reason for your argument.

I don't know why there are so many complainers about this pool. I, for one, will be pointing my hashrates at CoinShift for the forseeable future. The feature that does it for me is the lower daily minimum payout. Every other pool I looked at has a 0.01 BTC minimum for a daily payout. CoinShift is set at 0.001 BTC. I'm not the kind of person who's got a warehouse somewhere with a massive number of mining rigs. I'm just hobby-mining with my gaming rig. 300 kh/s is not enough to get 0.01 BTC in 24h, especially if I use it for gaming instead. But it IS enough to get 0.001 (just a little bit more than that, actually) every day.

I literally signed up to this forum for this one post. I was tired of seeing everyone complaining about not enough btc/mh/24h. Fuck, try doing it with 1/3 of a MH! Quit bitchin', you're all getting paid to do close to (but not quite) nothing! This pool is about saving the coins, if I read the Mission Statement right, and not about being the most profitable, though they're trying (and managing) to keep up with the rest of them.

If Pool X or Pool Y is so much better than this one, go hang out on THEIR forum page. Stop giving bad reviews that wrongly influence people away from CoinShift.

Oh, and @Coinshift, whoever you are, you can rest assured that your pool's total hashrate will never drop below 300kh/s. It's not much, but I'm not going anywhere :) Except for a couple of my smaller hashrate miners, just to fill the minimum at the other pools I tried.

Hi  Coinshift- 

I have not received a payout in a couple days.  I just want my remaining balance as I have stopped mining.   I've emailed you but have received no reply.

Please send me my balance so I can combine it with the BTC I already have and cash in.

But my wallet, Blockchain.info, and other explorers like Blockr.io and Bitcoinchain are not seeing this transaction on the chain.

https://blockchain.info/tx/b2026de0976e8512841b51cb512ad22ff1350065af49855eca686208a33683a0
http://bitcoinchain.com/block_explorer/search?search=b2026de0976e8512841b51cb512ad22ff1350065af49855eca686208a33683a0

Usually if the issue is just with Blockchain.info, the other block explorers show the transaction, but in this case, none of the explorers show that transaction.

Is there an issue with your bitcoind instance or payment system?


UPDATE: Nevermind... the transaction finally hit the blockchain and has 2 confirmations, but it took a long long time to get there. 

Well, I hope switching hash this way will help the market as a whole, because profitability sucks balls no matter which of the switch-pools I mine at.    :-\

Thanks for relaying that. It was a huge bummer -- fortunately AUR has hit their hard-fork which halves the block time (and maturity time) in addition to adding a better difficulty adjustment algorithm. Hopefully we'll see that coin get much healthier over the next couple of weeks and we can re-enable it.

It was rolled in to your normal one -- if you mined some of the AUR you should have seen a sharp jump in your balance.
LTC is in the rotation, but only if we hit a certain hashrate threshold. The problem we have with LTC is that our hashrate isn't quite high enough to mine it without luck being a significant factor. We had a period of bad luck while mining LTC that dropped our BTC/MH below the LTC line, which drops our hashrate even more and the problem compounds! However, things have definitely stabilized recently and our hashrate is doing pretty well.

Hi Clocker -- your remaining balance has been sent, thanks for mining with us.

Adding two more coins tomorrow, let us know if you have suggestions!

Keep in mind that they must be traded on an exchange with a trade API and have a fair amount of volume in BTC.

Couple questions:

Is there something wrong with the website? Some of the graphs on the stats page (both pool and personal) are not loading, and the page itself never finishes loading...

[EDIT] Never mind. A restart of my laptop fixed that particular issue...but not the other one...

And, if not, is there some other reason the graph (and my wallet) shows no payout today?

bcboy

^ yeah no pay out today or its extremely delayed?

@CoinShift

I have a suggestion:

I'm not sure how difficult this might be to implement, but there's something I noticed when I switched on debug mode for my miners today. Keep in mind that I run each miner instance (minerd, cudaminer) as a different worker id, and each computer as well. Every miner, when it connects for the first time, gets a diff of 256, and then adjusts diff to the miner after a share (or a few?) are submitted. With some of my workers, it takes a long time for that to happen at 256. Yes, I know I could always combine them into one worker id, but then it would be more difficult to track each thread's performance, and nearly impossible to identify at-a-glance which one is not mining; this helps keep downtime to a minimum.

What I'm wondering, is it possible for the pool server to 'remember' the last known diff value for each miner? Or, perhaps implement the d=x schema I've seen at other pools?

bcboy

Just got my payout! I guess somebody was late to work today?

You need to relax about your payouts. lol

And you need to relax about your bossiness? ::)

It's not like I've been here for months, bitching each day if it's even a second late. I mentioned it once. Well, twice, when I got it...And I wasn't the only one.

I was joking mate...

Well, either that was a very subtle joke, or I just didn't get it...

Perhaps, this is another example of missing <sarcasm></sarcasm> tags? This is text. Tone-of-voice doesn't translate that well...

Eventually everyone turns into a bitchy boy

It isn't eventually yet. I've made a grand total of four (now five) posts. I've been a member for only three days. I know everyone likes to pick on the new guy, but feel free to move on to the next suck--I mean, target...

something happened earlier today where my hashrate was cut in half, it appears its only showing my one card and cpu miner hashrate not the second card.  My address is 1YQh5CQWz9eEtVCLxcTHmjqNqrdtTYxZU  Please let me know whats going on.

Sounds like an impossible question to answer from the pool operator's side.  Whenever the pool is almost 100% litecoin or doge, my hashrate is exactly as expected.  For other coins with more variance my effective hashrate drops as much as 5-10%.

My chart holds steady as far back as I can see it (been mining here awhile).  Just have that 4 hour dip in half for some reason, not a big deal could be a lot of things.  Doesn't hurt to ask though.

There's been some hash-redirect attacks on other pools, lately. I don't know if this problem affects coinshift, but it might. If it hasn't already come back online, the first thing I would suggest is restart your miner software, or perhaps the whole computer. That should get your hardware pointed back at coinshift, if it was redirected...

Use the latest version of Kalroth's cgminer fork and add this to your config, just in case.

"no-client-reconnect" : true,

This!

I'm using an nVidia card, so I'm using cpu-miner and cudaminer. Is there an equivalent definition for those? Is it even an issue?

Now that I can see all the chart for the day the hash dips down in a straight line over several hours?

Most likely you have something wrong going on with the system. It could be caused by so many things, it's impossible to make any suggestions other than monitoring it closely to find out what it is.

Are your cards cool enough so they don't throttle?
Are you load/balancing with another pool?
What's your ping? Your connection might be dropping.

--
No idea about nvidia versions bcboy.

I haven't seen it happen to me yet, and I haven't seen any posts about it by nVidia miners. Maybe its like how there's more viruses for Windows than Mac. Not NEARLY as many people use nVidia for mining as those who use AMD (and therefore cgminer). Target the larger audience, so to speak.

Figured it out!  Last night the monitor wouldn't resume after sleep so I checked the connections.  I didn't screw I the dvi plug and the kitten got behind the pc and left the plug barely making a connection lol.   Must of kicked screwed everything for up awhile!

You'd be spot on if it wasn't a protocol related exploit. It affects even ASICs if the pool is compromised. :)

--
omgboss, if you're on Windows 7, disable ULPS so that you won't have to connect a monitor or a dummy plug with resistors attached to keep your GPUs alive. You're lucky them cats didn't cause more damage but keep them away from the rig. lol

The plug that came undone is my primary card for display that I also mine with.  I use the faster card in the second slot, doesn't need dummy plugs or anything.

So, theoretically, I'd have the same risk as the AMD-miners? Thank God for stats pages!

So I just went to check out my payout for today on the coinshift site...it says the payout was made as usual.

However, when I went and checked my wallet, there was no payment made to me :/.

When I click on the tx ID link that takes you to block explorer, it says transaction not found. Clicking on any of the previous tx IDs from different days shows valid transactions on the blockchain.

Anybody else having this problem? I would really like my bitcoin that I earned >:[

Same here, any solution ?

Um, yes? The solution, apparently, is to not have kittens...


Good thing you read the whole thread, huh?  ::)

Anybody else notice how last night's work is almost completely unexchanged?

Not that I don't trust him, but it's been a LONG time since I've seen a post by CoinShift. This would be the perfect time to speak up!

[EDIT: The majority of my unexchanged just paid out a few minutes ago. Is this the same sort of thing I saw at Middlecoin, Shift? A manual trade to get the best value? Should we expect to see more of this?]

I would like to see some of my proposed suggestions implemented. Especially the part on keeping on top of new altcoins released. You can be lazy and just see what ipominer.com is adding as a guideline to save some research effort.

Are the stats not working?  Current balances haven't updated since the last payout.

X2

I'm new to this so I'm apologising ahead for my noobness but what's going on? Why is it "flat lining"?
Or not updating, don't know what's the best way of describing it, but I've checked as much as I can and there seems to be nothing wrong on my end, it's mining, chugging away and nothing but a straight line...

Edit: I can't honestly be accurate, but because I keep on checking the stats, I think it stopped changing around 3 hours after the last payout?

Wondering the same.. there's huge estimated unexchanged spike now in the end of the flat line. Same wonky graph on personal and global level. Some coin causing trouble? Like we've mined single coin for hours which just all suddenly got mature.

There's been all sorts of strangeness going on with the stats the past couple days.

On the 10th, I saw a huge rise in unexchanged, with no rise in exchanged, until very suddenly, it all got exchanged. Then, on the next payout, I only got a partial, with about a third of my balance not getting paid out. The next payout, I got everything, like normal, but then it all flat-lined, as several people have mentioned already. This morning, I found that my unexchanged had jumped up quite a bit, to about the level I would have expected if it hadn't flat-lined.

I'm not really sure what's going on, if its a problem with the pool itself, or just the stats. And because we haven't heard a word from CoinShift about it (I've been checking reddit and Twitter, as well as here), I have to admit I'm starting to lose confidence in this pool.

Where the hell are you, Shifty? Talk to us! Enquiring minds want to know!

One thing I really liked about this pool was the communication.  Now with the lack of it coupled with low payouts/incorrect stats I've already pointed one card somewhere else. 

You're not the only one. The pool's hashrate has been steadily declining all day. I'm not ready to go elsewhere just yet, but if this continues for too long, I'm going to have to do so...


WHERE THE HELL ARE YOU, SHIFTY?!?!

Finally! Word from the Shiftmeister!

https://twitter.com/CoinShift

"Something is blocking the unexchanged stats from updating, we're looking in to it. Holding back the payout that's solved."

ugh this is how middle coin started... then he banished completely i hope i am wrong.

Not much news since the last tweet.. at least stats are showing something is moving somewhere.

It's funny you went from up there...
To....

 
So much for stop complaining and quit bitchin  ::)

Yes, well, if I didn't feed the trolls, they'd starve. Clearly, you've been fed. ::)

You will note that my original statement said "I was tired of seeing everyone complaining about not enough btc/mh/24h. Fuck, try doing it with 1/3 of a MH! Quit bitchin'."

And this isn't about btc/mh/day. It is about something being broken in the pool. The two are entirely unconnected. And, given the severity of the current problem, I feel it is quite normal to want some answers.

What surprises me is that you have so little to do in your life that you feel the need to track mine...

Good day. I said good day!  :-X

Eventually everyone turns into a bitchy boy...

And some, into a broken record?

So much for signing up for just a single post... Re-Read everything you said in that post...

*sigh* Why am I such a troll-magnet?

Whatever, man. You don't like what I have to say? Stop reading it. Problem solved.

Profit is good today...coinshift is doing a great job  :)

Yes, today was awesome.

Seems like all the multipools are showing better numbers. Looks like we've lost a few miners to new pools...we're less than 2 GH right at this moment...

That's what happens when you don't keep up with newer altcoins that get released -- which I've been clamoring to coinshift they need to do. I don't even see whitecoin or asiacoin on their pool rotation list, what the hell is coinshift waiting for? An invitation?

I agree on this.

I'm mining at ipoMiner, quite interesting, they are always ahead on adding interesting coins, one of the first getting WC and ASC

Yes coinshift please mine those two asap....

Today we added Fluttercoin and Whitecoin.

We can add one or two more today. Asiacoin would be hard since it's not traded on Cryptsy, but we'll run the numbers and see if it would be worth it.

Anyone know what which "secret" coin Wafflepool is mining with random rewards in the 250,000-300,000 range? Will add it ASAP.

Happy to hear from you!

@Coinshift  - Really like the idea of the pool, and have been happy with my results mining the last 2 weeks.  Like the VarDiff and the lower payouts.

Was wondering tho if it would be possible to add a simple chart bellow the graph with similar information in plain text.  
Just something like:

Worker |

Avg MH/s |

MH/s current |

Reject Avg |

Current Reject

Make the average over the last 12 or 24hrs, something like that.

Reason I'm asking is the graph is great, and the total MH/s is great, but my workers hash speed is very spread out, and its had to tell what my slower works are doing with just the graph.  If my total MH drops, it would be nice to see which worker is being slow and see if I need to do something with it or that computer. 
And I like the fact the graph is an image, loads great on smart phones so please don't change that into one of those interactive ones.

My payout today was not recieved by my wallet.

http://blockchain.info/tx/268af44752fec4d58e9ec7b9df78da485b177ceb659ea30bd774982f06385b11

Transaction not found.

Wallet: 12FEXEDRdDQBQUyKE9p8FncbvLmLokoBpZ

The transaction was broadcast just fine.  Blockchain seems to be missing a lot of unconfirmed transactions lately.

http://blockr.io/tx/info/268af44752fec4d58e9ec7b9df78da485b177ceb659ea30bd774982f06385b11

Be patient, it should confirm eventually.

Interesting. I closed and reopened my wallet client, and there it was (unconfirmed)!

First time that has happened to me, so I was a little concerned. Thanks for the tip about blockchain!

Didn't get a payout on 25th Friday, and today's payout -26th- was 1/3 of the Confirmed Exchanged.
What is going on? Can anyone shed some light?

Same, looks like a lot of the un exchanged got traded though

what wallet are you cats using?  I recently had to -rescan on the bitcoind and then rebuild/rescan inside of Armory.  Took care of my unconfirmed payouts.

I should have explained better, its not a payout that is missing from my wallet, the payout from 25th never happened, nothing came nor shows from "coinshift's payout history" to me. I had Confirmed Exchanged to be paid, but nothing was. It continued to build up, and then on the 26th, only around 1/3 of the now current Confirmed Exchanged total (Friday's mining plus Saturday's) was paid. And it just keeps on piling up. It's not a huge amount, but if it continues to build up and just gets "left behind", eventually will matter

EDIT: Problem solved, just got a payout at 3am.

Most likely it's not relevant any more but on the 25th of April Cryptsy added: " BigVern @cryptsy: New Markets Added: CINNI/BTC, COMM/BTC, AC/BTC"
Apologies if I'm overstepping but I do like the concept of this pool.

Whats the deal with Coinshift? Payouts haven't been on time (or happening at all) the last couple of days? It was at 17:54 every day for a week straight and now I haven't gotten one in 36hrs+

I don't mind waiting, but some word from them would be nice.

http://twitter.com/CoinShift


There was a payout late last night...hopefully everything is back to normal :)

The pool had a huge reject spike and a second smaller, is everything ok now?
EDIT: Another even bigger now, how do I interpret this, what does this means?

Is the pool down? Getting a 404 on Coinshift.com

http://coinshift.com/account/12WSWR23fBaPy24cyjSZTzUTpKB5BdWBL8/

Hi, if you look at the link above, you'll see there's some unexchanged BTC for a couple of days now, is there any reason why it's taking so long to confirm this last little bit?

Thanks.

I have been using this pool for just under a month now.  I like the stats, I am more profitably than when I was mining litecoin directly.

My biggest gripe:
We pay out every day if your balance is >0.001, so you don't need to trust us with holding your coins.

While they do pay out every day (when the payout system is working), I am not fully paid out.
On multiple occasions, on payout, I am leaving behind a fair amount of BTC.  .008 in one case, which is 8x the amount of their minimum payout balance.

Look here:

http://www.pendulus.org/images/balance.png


(Exchanged is dark blue, unexchanged is light blue)
Notice on 04/30, I had a full payout and the graph bottoms out.  Every day since, I have not.  I emailed them about it, and they said they were looking into it.  I emailed them about it again, and I've never heard anything else.

I want to report that today I received a full payout. It appears they have resolved the issue!

WHats going on with unexchanged?

I thought it was my stats till i looked at the pool stats.

Estimated Unexchanged  ???

Mine looks like yours tooo.  I  don't like the low payouts lately

Anyone else getting connection refused?

I still have a small amount confirmed that's not been paid for quite a few days now.

Minimum daily payout amount is 0.001 -- what is your current balance?

Current profitability is 86% ltc.  The FAQ says if nothing is  more profitable than LTC then they mine 100% LTC.  Why isn't that happening?

Haven't seen any updates here in awhile.  With Scrypt getting much less profitable and heat becoming an issue in the Northern Hemisphere, are there any plans to make a Coinshift X11 pool?

I want to try to avoid announcing any announcements, so let me just say this: Yes, we're working on supporting other algos. In the mean time, we're mining at 163% which ain't half bad!

Thanks for that. Also, I'm as guilty as any when it comes to complaining before complimenting.

So let me go against human nature and say, I really like the new statistical interface.
Specifically:

  * I like the way the hash graphs are broken out by miner. (I would love to get this in the API)
  * I like the ability to hover over the graphs and get the data from that time point.

Thank you for these enhancements!

Glad you noticed!

Yes, we've switched to a nicer charting system that is a bit more detailed and shows you more information when you hover on the graphs. It's still a little rough around the edges but it's definitely an improvement.

We also split out a graph for each of your workers now, which was a highly requested feature. Sorry that took so long!

@jgauthier I will get you an API for that today

Hello! Just wanted to say I'm liking the new graphs as well.  Thanks for all your work.

I am having an issue however.  My total hashrate is reporting about half the value it should.  My individual worker hashrates are correct however.  In fact, the total hashrate is lower than my fastest individual worker!

My miners appear to be working normally, I just want to be sure that I am being credited for the correct total.


Account is 1Q2TQcmESrVt9qGtKQYQGfcVXBKkJxny9e.  Thanks for any info.

Hello,
I want to ask you why in your pool I have too many hardware errors (hw) than other multipools?
I have noticed that I receive that many hw when share difficulty increasing.
I have A2 Terminator scrypt miner.
Thank you.

Because the difficulty is going too high for the A2 miner. I'm seeing a difficulty now of around 10048. The longer an A2 works on a share the greater the chance of it getting a HW error and dumping all the work.

Would be nice to specify a difficulty at Coinshift to allow for this, my A2 likes 2048 or 4096 difficulty shares best.

Thank you very much for the informations.
Could you tell me how can I specify a difficulty at Coinshift?
At the other pools you can set it in password d=xxxx, where xxxx is number between 128 and 65536.

how long does the VARDIFF take to reach its optimum difficulty setting? been on for 2 hours and it still hasnt stabilized. im using zen miner/zencontroller on 5 Furys. i emailed support and they said my Diff is too high. (1920) mine needs to be at 512. why cant we set it manually?

Thanks for the feedback, we weren't aware of those HW issue problems. We will add a manual difficulty setting this weekend.

Cheers!

We added three fresh coins a few hours ago. Our internal BTC/6h graph is showing over 125% -- should see the 24h graph rising to meet this over the next few hours

It was a good spike. Now we're at 82% LTC. 

I've asked a few times, but not really got a response.. Why aren't we mining LTC 100% like the FAQ says?
18% is a LOT.

We do mine 100% LTC if our hashrate high enough and the other coins drop below 100%. However, even if we're mining another coin that is ~102% vs LTC, due to luck and spacing between blocks we may fluctuate between 97% or 106%, for example.

The more significant drop we saw today was due to Cryptsy's API being down ALL NIGHT. (https://twitter.com/cryptsy/status/481236514459095040) With their API down we have trouble estimating which coins are the most profitable to mine and we ended up not spending our hashrate as efficiently as we would have otherwise.

Honestly I spend about 20% of my time dealing with/working around Cryptsy's problems. Their wallets go down, stop accepting deposits, APIs go in and out and return stale data, etc. Last night I got pretty pissed and called them out publicly on their shit:
https://twitter.com/CoinShift/with_replies

But I doubt that'll help much -- and it's not like we can switch exchanges easily, the other ones just don't have enough volume.

Good to know! I will correlate Cryptsy and Profit. It sucks everyone is so dependent on them.  If they are go go under, that's a big problem!

had over .001 and wasnt paid out today.

Should i post my btc address?

I think that developing a Coinshift X11 pool is not a good idea.
1st: I don't like the idea of multipool
2nd and most important: Creating a multipool for an algorithm full of FPGA?

I've noticed the VARDIFF is far too high for my gridseed blade, and a lot of work gets missed and rejects are too high. Blades like to run at diff 512, since there are actually two independent modules, rather than just one submitting the shares. Unfortunately, they cannot be split into two independent miners. Since it get's treated as as one, the VARDIFF goes too high and efficiency goes right down/ Has the option to manually set diff been implemented yet? Because this is otherwise a really nice pool. I've been looking for somewhere to switch to instead of nicehash, because I'm sick of spending most of my time getting work restarts, instability and constantly being retasked to different users.

Good news: you may now set a manually difficulty setting by using d=<diff> as your password.
For example:

The 2% fee includes everything (exchange fees, etc.), right?

65% LTC profitability
0.00039 BTC/MH/Day

Cryptsy is up, the other coins have dropped well below 100%. The hashrate is 1075.634 MH/s.
Should we be mining LTC yet?

I think it's a good idea.  I'd like to continue to use coinshift as a service.

Unfortunately, here's the reality:

I have a GPU rig that does ~3000Kh/s (scrypt)
I have GSDs and Zues that do ~10000Kh/s.

I moved my GPUs over to an X11 pool (nicehash)

GPU Payout 24/h:        0.00448848
CoinShift Payout 24/h: 0.00360998

The GPU rig which is 1/3rd of the scrypt hashrate has pulled in more BTC in a 24h period.
It's not always more, but usually it's pretty close. 

What are your recommended diff-settings for variously sized miners (hash-rates)?

I think that's better without writing diff, don't you think so?
What's the main difference of setting up miners with:

or

switched to here from westhash as they are just getting less n less for payouts...but after 24hr my exchanged balance was around .032 btc but i only got paid .006btc? i'm sure the answer maybe in this thread somewhere but i'd just rather ask :) looked at the FAQ...just saw something about .001

Coinshift,

There is a problem with coinshift.com changing coins.  Currently our profitability is at 80% mining AUR and HIDDEN and according to your FAQ, if LTC is more profitable, it will mine it;  how come we are not mining LTC now?

Well I guess that Coinshift no longer supports his stuff since there is no real contact address for his site and no response here...

time to switch pools then since he is not supporting his site.

I've had an unexchanged balance of .002[and change] for over a month.  I've emailed them twice with 3 weeks in between.

No response.  I really liked this pool.  I'm disappointed that they never seem to mine LTC when other coins are less profitable, and the responses for support are falling on deaf ears.

A shame. 

http://coinshift.com/shutdown/

Good luck to all involved with their future endeavors.

sorry to see my favorite go down.
