Hey Flound.. have any idea why the difficulty is so high atm? It's almost twice what the hashing on the network is. Seems backwards.. more hash power = higher diff supposedly yet the diff is zooming these last couple weeks beyond hashing growth.
I've watched it go from 38M to 42 to 48.6, back down to 41.8 and today its at 50+M.

Which coin are you talking about? Ahh.. sorry, LTC. T. Oh, I'm not sure you're reading the graph correctly.. LTC difficulty is actually over 800 now, there is a second axis that difficulty is plotted against, on the right side.. It's not the same as the hashrate. |
|
|
|
it all appears to be down?
I'm making a few minor changes, so the website is down atm. All pools are up except NVC currently. |
|
|
|
What happened in the last LTC round? nothing shows under uncomfirmed, and it didn't carry over to confirmed.
Actually you're right, on 378792 it looks like there was a DB error while running the payout script.. Unfortunately all the shares for that block are gone and the payouts were not completed properly. I don't really have a choice right now other than to pay it based on all the current shares in the DB. If you've been on all day your reward should be about the same. |

question. Would it be more profitable to pick a "winning" alt coin of your choice and mine that specifically? Or jump around to different/ currently popular alt coins when difficulty changes etc etc.
If you believe a new alt coin will become the 'next' BTC or LTC, you're welcome to mine that coin exclusively and hold it until that happens, however, you could accumulate more by mining whatever is most profitable and trading it for that particular alt coin of your choice. |

well i find the multiport to be switching quite regulary to MNC, due to low payouts because of 2 MNC per block, which is pretty useless, or today, to NVC, which is useless aswell, because it takes ages to hit a block  The multiport takes the block reward into account when deciding which coin to mine. MNC only rewards 2 MNC per block, but we find a block every few seconds when the multiport is on MNC. 2013-06-28 01:22:15,388 CRITICAL interfaces # Block 000000008dede75b55424ee500e93cd698f96cec62d877afa4a3828d77dc948f ACCEPTED

NVC difficulty is much lower than LTC. If it's taking 'ages' to find a block it's due to bad luck. I believe when the multiport was on it earlier it showed an average block time of about an hour. |

ltc value went up at btc-e last hour and we still mining nvc...
2013-06-26 15:02:21 Profitability calculation now uses an average from several exchanges. We should no longer experience flaky behavior on the multiport when one or two exchanges are down.

Which coin are you talking about? |
|
|
|
|
Someone brought up this idea in IRC today, would anyone be interested (enough to pay for) a 'personal' multiport, where you could select the coins you wanted to mine?
|
|

yeah stratum on port 7777 has been dropping in & out for the past 12 hours, a real shame This issue should be solved. The script now checks to see how long we've been mining a particular coin, and if we have more than a threshold (currently 10 minutes), it switches to the new coin immediately. This should at least partially solve the 'flapping' issues we've been having where the port switches between two coins because of very minute changes in price. I'm also working on a much more robust price determination algorithm that will use averages from multiple sites. Of course, it doesn't help that vircurex, btc-e, and bter are all down right now. |

I also fixed a bug recently that was probably hurting our profitability -- there was a bug in stratum where for some reason it would start handing out inhumanely high difficulty shares (like with diff of 3000+) to some workers. So I put a cap on the scrypt vardiff at 256. I've also reduced the minimum share difficulty to 16 on some ports so the slower miners could submit shares faster. I plan to do this with all of the coins that have vardiff enabled.

Is it just me, or is the multiport somewhat unstable today?
I've got my miner set with port 3334 as my first failover pool, and I've noticed it in use on several occasions thus far today.
Setting a failover might cause issues. I've found that when multiport switches currencies and I have a failover, it switches. Make sure your settings are set so that when multiport "comes back up" that your miner goes back to it. It goes down for a few minutes during currency changes. It only actually goes down for 2 seconds, it shouldn't be a few minutes, although I have seen up to 30-45 seconds on my miners. I bet there's a value you can tweak in cgminer to control how often it checks to see if the higher priority pools are back up. |

Is there a place to see what formula you use to see which coin is more profitable to mine? I don't seem to agree that FTC is the best now. Coinchoose says the same look at coinchoose adjusted for stales, it agrees. Going with a straight profitability is fine if you can expect 100% PPS somewhere for each coin, but if you're counting on finding blocks then stale/orphans have to be factored in as well as faster coins causing more rejected shares. that all lowers the actual profitability, i'd be interested to see flound's actual stuff though. While agree to a point with what your saying I think some of these estimates are off. Wdc according to coin choose and here sits at almost a 30-50% decrease in profitability due to stales/rejects/orphans. From my experience mining wdc exclusively I only get about 8.5% stales/rejected and know there isn't that many orphaned blocks to make up that difference. I've actually made quite a bit more revenue mining wdc instead of FTC for the blast few days since my actual results are much much better than what multiport suggests. I also would love to see what calculations are used to figure in that profitability. +1 I would also be interested in seeing what percentages are being assumed for the stales and orphans. WDC: mysql> select count(id) from winning_shares where confirms=-1;
+-----------+
| count(id) |
+-----------+
| 882 |
+-----------+
1 row in set (0.01 sec)
mysql> select count(id) from winning_shares where confirms>120;
+-----------+
| count(id) |
+-----------+
| 12842 |
+-----------+
1 row in set (0.00 sec)
So we have 882/12842 orphans. That's 6.8%. DGC: mysql> select count(id) from winning_shares where confirms=-1;
+-----------+
| count(id) |
+-----------+
| 205 |
+-----------+
1 row in set (0.00 sec)
mysql> select count(id) from winning_shares where confirms>120;
+-----------+
| count(id) |
+-----------+
| 3006 |
+-----------+ 205/3006 also = 6.8% (interesting..) So, the profitability calculation should subtract around 7%, minus whatever stale percentage we're currently at. Right now that's normally around 5% from what I've seen (I don't have historical stats on this, though, and the number of shares kept in the DB for WDC and DGC is fairly low due to the low difficulty.) I'd say 15% for both should be fairly conservative. We're currently at 20% for DGC and 25% for WDC. (The extra 5% for WDC was based on it having slightly faster blocks than DGC) |

Sort of an odd bug: My payout threshold is set to 99, but payout today occurred at 95.
That's.. strange. Higher payout thresholds are available now for all coins.. (up to 999) forgot to announce that. |

Setting a failover might cause issues. I've found that when multiport switches currencies and I have a failover, it switches. Make sure your settings are set so that when multiport "comes back up" that your miner goes back to it. It goes down for a few minutes during currency changes.
From what I can see it does appear to be switching back to the multiport eventually, I just noticed once or twice today that it was mining on failover for considerably longer than the minute or two it typically takes to switch coins. Yeah, I noticed this earlier. It's a result of a bug in the switching code. I'm going to fix that tonight. Basically what was happening was it was doing the 'switch' every 2 minutes, even though it was staying on FTC. |

Implementation of profitability or auto-switch history would be nice. I mean something like 25.06.2013 1:00: LTC profitability is 1.42, switching to LTC
25.06.2013 1:32: FTC profitability is 1.55, switching to FTC
... It's on the list. |
|
|
|
Something is up with FTC: I can see multiple blocks with the same # of confirmations. Is FTC under another attack? Is there a fork?
If so, it should taken out of the multipool auto switch.
Nope, just me being a bad programmer. Edit: This isn't related to the downtime.. I'm not sure what caused that, feathercoind was just hung.. |

FTC pool was down for a couple hours.. It's back up now.

LTC hot wallet was empty, I just sent some LTC to it, you should be able to withdraw LTC within 20 minutes or so.
