Can you please add an automatic exchange service to BTC or LTC and an accurate profitability statistic in BTC or LTC the account gots in 24h 48h and 1 week.
And also an average the pool gots in 24h in BTC/mh/d for complieance of comparison with other pools.

I use 5 for the harder coins, 10 for the easier ones.

By harder, you mean higher difficulty, right?

Yes that's correct.

Would be nice for me if we had a once a day payout of all coins.  So less dependant on the amount of each coin, more on the frequency.  Since so many of these alt coins are worth so little per coin, some of these payouts are for so little BTC equivanance.  For me, can't speak for others, I'm mostly about tracking my per day profits and the closest I can do with that, unconfirmed shares aside, is to allow the coins to go for a 24 hour period and then sell them all out.  With the caviet that they are 1 full coin or more to not incur extra fees when withdrawing.  Just thinking out loud.

I could add something like that.

[jabba1]

How many miners can mine on the same accound and same worker with differend ip adresses without getting blocked or broke something ?

Unlimited.

Throwing 2.2MH/s at the pool now.   I've flustered myself enough with the brand-X multi scrypt pool and statistics ad nauseam and I'm resting my hash here for awhile.

I don't think this would be a good idea. If many people cash out all their coins at the same time to auto sell on Cryptsy then the coin's value would quickly drop. I cash out my coins roughly based on their value:

NVC 1
FTC 2
MNC 5
WDC 65
DGC 12
LKY 100
ARG 14
PXC 42
MEC 36
CAP 14
CGB 1

You misunderstand the point. Cashing out your coins from multipool daily doesn't mean you are going to sell them. That's a choice. Cashing them out at a certain quantity and selling everyday is no different than if my coins go to Cryptsy once a day and then I choose to sell them.

Please send Flound maybe 60+BTC or 3000+LTC for the work you are asking him to do just because you want to be lazier.

Be well.

Hi flound.  Have you got some orphans you forgot to clear out of the CGB pool?  I've had an unconfirmed balance of .2360 for about a week.

[Aurum]

My rejects are running 38 to 47%      

And a miner died of an unrecovered stratum disconnect  

[raveneye]

Flound,
MEC is about to reset the block reward again.  At block 63000 it will drop from 125 to 75.  This will likely happen tonight or tomorrow some time (current block is 62003).  Given what happened last time it reset, I wanted to make sure you were ready for it this time.  It might even be good to disable it from the MP until it resets to help it through the transition.

It has a really weird retarget function.  It recalculates every 9 blocks with a weighted average of the last 1296 blocks mined using a bizarre impulse response distribution.  This is what causes profitability to climb for a couple minutes when MP switches to it, and continue to drop after we switch off it.  It is one of the reasons it took so long to recover when the reward dropped from 250 to 125.

Restarted miners and 30 minutes later dead again from unrecovered stratum disconnects.

Am I the only one afflicted with this scourge?

This was a definite issue last time...but is corrected as long as MP is running the updated client. Difficulty will be adjusted using Kimoto's new "Gravity Well" and this kicks in at block 63005, I believe. I'm looking forward to seeing it in action.

Can you post your settings?  And which pool are you using?

Yup, we should be good on the flip this time .   It will make megacoin more "hop" resistant, as well.  Multipool is only going to mine it when its profitable based on the price, the difficulty won't matter.  It may actually cause some problems for multipool because it will only be able to mine a few blocks before the difficulty quickly adjusts.

Flound, do you have multipools MEC client updated?

[raveneye]

First of all, Flound needs to update the profitability calculation to use 75 coins instead of 125 coins at the right time.  Coinchoose and Middlecoin will have to do the same thing.  Otherwise, one of them will grind your profitability down to 60% of other coins.  If you don't believe me that this is done manually, scroll through the multipool and coinchoose threads and see how many times the developers have to be told of the change.

Looking over the new algorithm for MEC, I don't have a lot of hope for MEC.  It looks like a clever developer trying to be too clever, and I think the result will be bad.

As I understand it, the algorithm works like this:
Next Diff = (Average Diff over the last N blocks) * (150 seconds) * N / (Actual Seconds for last N blocks)
where N is a number between 144 and 4032.
The "clever" part is that N gets smaller when the diff changes quickly and N gets larger when the diff is stable.  The idea would be that when there is a quick change in hash rate, it reacts quickly.  When the hash rate is stable, it reacts slowly.

The problem is the first part of the algorithm has momentum.  This is one of the things that caused so much trouble with the transition at block 42,000.  Even after the MP switched off around block 42130, the difficulty kept climbing for about 70 more blocks (which took 2 days).

For example, if N is 144 and the coin-hoppers mine a fast 50 coins and switch off the coin, those coins will still be counted in the average used for the next difficulty while the faithful have to grind on 94 coins themselves.

The change in direction will also increase N, causing the permitted change to be smaller, and allowing those 50 fast-mined coins to linger even longer, forcing the faithful miners to spend even more time trying to create even more blocks necessary to bring difficulty back down.

The idea was clever, but not practically applied.  If instead of using block counts for PastBlockMin and PastBlockMax, he had used Time (i.e. PastSecondsMin and PastSecondsMax), then used blocks/hour instead of hours (seconds) per block for the calculation. That way if the coin slows down to 2-4 blocks per hour, it doesn't take days of grinding to get the 50-100 blocks needed to push the fast blocks out of the window of consideration.

Hopefully, I am wrong and it stays profitable to mine for the faithful and keeps producing blocks.  Unfortunately, I think that every time it gets marginally profitable to mine, MP, MC and CC will slap it down and create problem like it had with block 42,000 where transactions don't confirm and 2 guys are stuck mining it for days waiting for it to recover, only to get slapped down and have to repeat the cycle.

To be honest, the simplest solutions are often the best:
Retarget every block
Diff Adjustment = (Target Seconds for last 10 blocks) / (Actual Seconds for last 10 blocks)
If (Diff Adjustment < 0.99) New Diff Adjustment=0.99
If (Diff Adjustment > 1.01) New Diff Adjustment=1.01
New Diff = Last Diff * Diff Adjustment

Coins that make frequent small adjustments have been the ones that have dealt best with Multipool/Middlecoin/cgwatcher.  They tend to stay very profitable all of the time, and then build up a strong base of dedicated miners which stabilizes their hash rate.

[raveneye]

Yup, we should be good on the flip this time .   It will make megacoin more "hop" resistant, as well.  Multipool is only going to mine it when its profitable based on the price, the difficulty won't matter.  It may actually cause some problems for multipool because it will only be able to mine a few blocks before the difficulty quickly adjusts.

You consider it a good thing that as soon as it is hit with any amount of hashing power, the difficulty will explode and make it un-minable?

Oh, and your MEC block explorer is down.  500 Error.
