It seems like Dogecoin has climbed up again to 1:th place on cryptsy again. +29.48 % up from last day. We are still mining it.  Grin

the next person who mentions coinwarz or dodge should be banned. if you are so smart, solomine or find your own pool and exchange everything manually but don't bother us with your wisdom. thxs
mining its simple math not religion.
op making good profit thanks to all miners, i think there should be room for suggestions and improvement and not just following blindly.


The OP is making good profits because he's good at what he does. There is no "simple" algorithm for predicting what a coin will be worth after mining it for a day, or even an hour... especially if it's not being moved at the exchanges. Also, the coin being mined by the pool is not made public, and h2o has indicated several times that he will not reveal it - that's pretty much "following blindly" and judging by the 200% growth in the last week, plenty of miners are willing to do just that.

If you don't believe the operator knows what he's doing after the last week or so there is probably nothing that can convince you that he does, and you can go mine somewhere else. I'm all for suggestions and improvement, but complaining that the pool isn't mining the right coin is pretty stupid after last week.

It doesn't matter if he says what the coin is in public, you just have to compare the working difficulty to the list.

I never said it was hard to figure out what the pool is mining, just that the coin isn't published. More to the point, his algorithm for switching isn't published.

Is it just me or is anyone else getting low accepted rates for the last 48 hours, has the graphs/stats changed maybe its not updating as fast as it used to?

I've come to the conclusion that It's not even worth mining until the switching algorithm is fixed. It's like finding a penny every day. It's been two days, surely it could have been fixed :/
There were some disconnect issues yesterday, however, since then I haven't had any issues. Payout today is already up to 0.1 for me, with 0.22BTC looking like where I'll end up... My hashrate is around 0.5-0.75MH/s under where it should, however, this could just be due to stales / pool variability.

I'll have whatever you're smoking ... 0.1 to 0.22 btc on 500-750 kh/s a day ... just wow Smiley)

Apparently you are already smoking. Read again Wink

Grin I'm running around 10MH/s on Middlecoin right now, however, most of the time I can find myself 9.2-9.6 MH due to stales / rejects :]

Hey guys,

  I know it has been talked about here before but it seems my CGMiner is reporting 840Kh/s with 0 rejected so far but the website and the python script on this board are both reporting much lower.  

  How long does it usually take to report accurately?

  Scott.

You can see that the diffuculty in cgminer is same as dogecoin on cryptsy. Also block time matches as well, its not hard to figure out what we are mining.

does anyone know why I'm getting these dips in temperature?
They seem to be for only short periods of time and I've only caught it in the act once but the voltages drop, the clock/memory cores drop and therefore the temperature of each card as well.

any ideas?
Most likely this is due to work temporarily not being available from the pool. The dips usually last until the next block is detected, then the cards heat back up :]  The problem is if the machine gets "stuck" idling and doesn't restart work automatically. Having multiple pools should in theory fix this, however, yesterday was still a little rough, with miners needing to be manually restarted.

ahh ok, thanks, I guess that makes sense!

  Scott.

The reported hashrates are based on your accepted shares over the last hour before the UTC timestamp on the report. If you had a high rejected percentage, or were unlucky and found fewer shares than your hashpower normally would, or if the latest report is 2 hours old (happens sometimes when the server frontend lags), then the reported hashrate won't match your CGminer values.

If it's within 20% of your nominal value, then I would not worry about it. It averages out over time.

Did the website change?

I can no longer isolate my address by using the format:

middlecoin.com/#<my address>

It just redirects me to the top of the main page.

Also, I've noticed very slow accepts/min as reported by my miner.

Hashcows it flies, at like 5-10/min but here it's like
Less than 1/min. Is that due to the lack of VARDIFF? My Hashrate seems fine.

Yes it's because of VARDIFF. With it, your difficulty can be as low as 16 and you would constantly be sending in shares. But here it's fixed at 512... you send shares in slower, but they are worth more. (averages out in the end)

Yup, it's done primarily to reduce the server load - even at 512 we were having some issues with the insane growth Middlecoin has experienced over the past week.

So is there no way to isolate my performance besides doing a search of the main page for my address?

I can't do that via mobile

use this, its the most mobile friendly solution i have found. i did not create this.

A lot of new people are asking about hash rate on the server not matching what they see locally.  There are others wanting to know why the temp or fans seems to fluctuate more on middlecoin than on other mining pools.  Both questions are kind of difficult to explain, but it really boils down to variability.  The server has no idea what your hash rate is locally.  What it can do is look at the number of accepted shares you transmit and come up with an approximate hash rate that might be expected to produce that many shares based on the difficultly of the current work.  There are times that in the short run you are lucky and get many solutions in close proximity to each other.  This would make it appear that you are hashing more than you actually are.  Other times the opposite happens and even though you are hashing at full speed, luck makes your solutions take longer than average and the server shows a rate lower than you are actually hasing.

This variability is compounded by the fact that middlecoin sets a 512 share difficulty rate and the pool automatically changes what currency it is mining from time to time.  In the long run everything will always even out to average, but if you only look at short periods of time it starts to look odd.  Slower miners will really start to notice this when the server switches to currencies with low difficulties.  Many times blocks are being solved on these currencies faster than your hardware is able to submit shares.  This can cause slower miners to see a lot of stale shares, or seemingly go long periods of time without submitting a valid share.  Again this will all even out if you look at things over a long enough time period.

Another factor that might be confusing people on their hashrates and accepted shares with middlecoin is a change made to cgminer.  If you are using the latest version of cgminer, any time middlecoin changes to a different currency it appears to cgminer that the pool went down.  In reality the pool is not down, it is just switching to a different currency.  If you have a fall back pool set in the latest version of cgminer it will switch to your fallback and will not switch back to middlecoin for five minutes.  This means that every time middlecoin switches currencies you switch to another pool for five minutes.  Cgminer waits for the pool to be "stable" for five minutes before switching back to your primary.  I'm not 100% certain, but I believe this is any version of cgminer later than the 3.5.X branch.  I know on 3.5.0 it will reconnect as soon as it sees middlecoin up, but on 3.7.2 it will wait five minutes.  You can either run the earlier version of cgminer with a fallback pool or run the later versions of cgminer with no fallback to avoid this problem.  Other people may be able to chime in with another work around.

There is more to it than what I've mentioned above, but I hope this helps some people understand that mining on a multicurrency pool like middlecoin might be a little different than they are used to on other pools.  You also have to factor in the fact that the different currency rates are always in flux so it's hard to nail down what a particular hash rate will earn on a particular day.  All you can really do is look at past performance and make approximations.
