Port 8080 is now open, for people behind restrictive firewalls. It does the same thing as port 3333.

Also, I disabled the coin that switches after like 30 seconds of mining it (SPT). I didn't realize it was disconnecting people.

That's because it's not worth it for you guys to hop on Spots. You only get a block or two then get bounced back out when it retargets

Ouch, that brings up a good question. Is it really worth mining NVC and selling at whatever price it is in x days? Prices fluctuate enough from hour to hour. Throw days into the mix and it just gets worse. I'm wondering if maybe we're not actually losing as a result.

As far as I know, it will fluctuate up just as much as it does down. I guess the question is how much variance is ok, for a profit increase? If NVC is 2% more profitable than the next coin, but might fluctuate 20% before it gets sold, is that ok?

Hmm, I haven't watched the prices over time. An idea, if it is fluctuating a lot but pretty much stays within two ranges (let's call them MIN and MAX) is to wait until the price is closer to MAX, then sell them off. If the price is closer to MIN, hold on.

I'm not sure how feasible that is with your selling script, though. If the range between MIN and MAX is constantly changing (ex. there are massive swings happening on the coin still), I think that'd be a new thing to evaluate.

And if the MIN->MAX differences are pretty small, just roll as it is because the loss shouldn't be too big.

...and now
[2013-08-18 20:52:17] Network diff set to 59.8M

 What coin is diff 59.8 million?!?  Anybody?

Take care


That one is Litecoin.

And the 21.2M one you linked earlier is Novacoin.

 My litecoin client says diff is ~913 and Novacoin ~340 so where does this discrepancy come from?  Does h2odysee apply some constant fudge-factor to throw us off the trail of which coin the pool is currently mining?

It's how cgminer reports the network diff, middlecoin just follows it.

 So I am also running a second instance of cgminer for Bitcoin and it reports a network diff of 50.8M - I appreciate your willingness to help but I'm just not understanding.

I read somewhere that cgminer reports network diff at 65,000 times the actual diff for other coins.  Why?  I dono, just seems to be that way.

 Thanks samfisher.  I pointed my miner at a few different scrypt pools and it appears as though the displayed diff in cgminer is difficulty*2^16 though I still can't understand the why.  I think I'm going to accept that there is a difference and let it go now Wink  At least I can figure out which coin we're mining on middlecoin.com now!

Thanks H20..   It looks like another subpar payout today...All be it not as bad as yesterday..  Why is my mmature Unexchanged Balance (estimated BTC) so High?

Because we have a bunch of NVC blocks that will mature on tuesday, I believe.

I would suggest to add a FAQ to the first page, to avoid people asking the same questions again and again.

Difficulty 1 Litecoin (read: Scrypt) shares are set at 65,535 ("FFFF" or 16^4).

Edit: to clear confusion a bit (as to how an even * an event = an odd. It's because technically 16^4 is 65,536 but since the computer reads 0 as the first number we subtract one (65,536-1=65,535).

this is a good pool, but 512 of difficulty is too high with low difficulty coin and my 480 Kh/s gpu:

do not have time to find a share, which already found the pool to the next block, resulting in a restart of the work by the gpu with a consequent loss of earnings from that block.

To be accurate, it's 65536, which is 2^16.
Meaning right now it's 88k/65536= 1.342 which is: DigitalCoin.

I have the same problem, my hash rate is reporting at about half on the website mining DGC, not due to stales, just that it is inefficient to use such a high setting.

From pool information on CGminer:

 Reject ratio: 2.9%
 Efficiency (accepted / queued): 14%
 Discarded work due to new blocks: 10896
 Stale submissions discarded due to new blocks: 0
 Unable to get work from server occasions: 40
 Submitting work remotely delay occasions: 0

I'm back at a 47% reject rate. I see some people are above that and some are way below. I just don't get it. With some of the coins I have a 0% reject, others go up as high as 60-70%. But I see some people (with high hash rates) that are always very low rejects, regardless of the coin.

I'm not sure what causes the reject rate but I think the 512 difficulty not using VARDIFF causes the  "Discarded work due to new blocks:" to be high and is killing smaller GPUs profit on those low difficulty fast block coins.

Wow that's some hashing power, more than enough for a 512 diff.   

I had a high reject rate with my 2x 7970's until i traced the issue to a crappy ethernet switch.  Not sure what the interaction has exactly, but I moved that rig on to my gigbit switch and the issue disappeared.

If I move to FTC/LTC/NVC/etc. I have a 0.1% or lower rejection rate with vardiff. Usually the vardiff ends up being set at around 260 and I have a steady 6.6 MH/s. As soon as I swap back to Middlecoin it all goes downhill again, Sad.
