Took a look at UTC, and like you said, current profitability is way down, and the network hashrate is only about 8 Mh/s (if my rough estimate is correct). Still haven't had time to look at JPC more than take a quick look at its [ANN] page, but it looks intriguing.
Quick question for you. I'm sure you've seen it often since you're into following these things up close. I've only 'noticed' it before (or at least I think this is the same thing) when real payouts have not matched expected payouts - I've chalked it up to other possible factors like inefficiency or outright pool skimming. However, yesterday, on DGB the issue was so obviously a network issue that I delved into it and discovered something very strange.
DBG was stuck on block 131993 for over an hour and a half, and I started looking at the block chain and I noticed that it had been taking progressively longer to find blocks, with
only an average of 10.66 blocks found per hour over the previous 24 hours and only an average of 19.25 blocks found per hour over the previous 5 days. That's extremely strange for a coin that's designed for 60 second rewards (60 blocks found per hour). As far as I can see, when going back and comparing when slowdowns occur, there is no correlation with difficulty what-so-ever. As far as I can see, the coin seems to get 'stuck' at random intervals.
http://explorer.cryptopoolmining.com/chain/DigiByte11,066,400 theoretical total coins per day = 461,100 total coins per hour = ~153.7 coins per hour at 1 MH/s or ~3688 coins a day, exactly what is reported as "Est Rewards" on What To Mine.
At 10.66 blocks per hour those totals fall to 1,966,130 coins day = 81,922 hour = ~27.3 per hour at 1 MH/s or ~655 coins a day (~1183 a day at 19.25 blocks per hour). That sure smashes whatever profitability there might have been to begin with! And, as I said to start, I'm not sure this is an isolated case.
Do you know or have any ideas about what causes this to happen?
Add:
Last 24 hours since block 191994 (purposely leaving the 1 hour and 45 minutes from 191993 to 191994 out of the mix): 8.25 blocks found per hour, for a total of 1,521,630 coins at an average of 63,401.25 coins an hour yielding 21.1 coins per each 1 MH/s of hashing power, or 507.16 coins on a daily, 24 hour basis.
HORRIBLE.BTW, I'm also wondering why CoinWarz and MiningPool.co both report around 1/6th the network hashrate that What To Mine reports (if those were correct, then a 1 MH/s miner would be getting around 24,600 DGB on a daily basis if the theoretical 60 x 24 x 7685 was actually happening). How are these discrepancies explained?
Independent of the actual network hashrate,
there's no arguing the fact that only 198 blocks were found in the last 24 hours on a coin that is coded to deliver 1440. What explanation might there be for that?
