Difficulty increase as clearly been slowing down for the past 48h clearly showing that the number of blocks found is lowering (as most of us miners sadly experienced).
Only = +0.01888007 which is ridiculous compared to what we were used to see that was around +0.07 a day if not more. The lowering started around 08/08. Lyddite will surelly have a nice graph for us
This is resulting in a huge increase in price which is great for us miners having to cope with lower and lower blocks each days especially since the last 48h.
I was about to close my little farm, might keep it up a little more...
My luck has turned for the worse also but 1-2 blocks per day is ok.
This will be a kind of pain point for Primecoin I think. The increased price on the exchanges probably will keep miners motivated despite the diminishing returns. Many more miners will be necessary to push the difficulty up to 10.
From what I have mined over while the difficulty has been > 9, about 10% are 10-chains, the rest all all 9 chains.
The high performance primecoin miner has had many fixes and optimizations over the past while and I believe that there if probably little left in terms of low hanging fruit there. Now that the "fractional difficulty" for 9-chains is high enough, tweaking roundsievepercentage, sievepercentage and sievesize for the best efficiency is where one should focus if one continues to mine intensively.
For those who are new to linux and the bash shell and are curious to find out what kind of primes have been have generated by their miners, here's the oneliner to I used.
primecoind listtransactions "" 100 |grep blockhash | sed -e "s/.* :/" -e "s/,//" |xargs -n 1 -I '{}' primecoind getblock '{}' |grep primechain
Append
| grep [CN]09 | wc -l
to the above line to count your 9-chains and
| grep [CN]0a | wc -l
to count your 10-chains. The "[CN]" in the grep keeps 09 or 0a in the latter hexadecimal part of the data from being counted. If you have more than 100 transactions in your account then increase the 100 to something greater than the amount of transactions for that account.
