The very first Bitcoin investment trust proposal is sitting on SEC's table. Hope it can get approved and goes to the mainstream retail investors:

http://pdf.secdatabase.com/956/0001193125-13-279830.pdf
http://www.secdatabase.com/CIK/1579346/Company-Name/WINKLEVOSS-BITCOIN-TRUST

The regulation might be a good thing as more people and organization can invest in this new type of currency.

If the mining of the XPM is not limited to big whales, and thus less price fluctuation, we will see better adoption of XPM and brighter futures. To most investors, the price fluctuation is risk. Investor does not like risks, and day traders are not investors.

hmm hp10 blows up on my core i7 795 box..



Just fyi, i tracked this down.. some how I added some text to my primecoin.conf file .. I think I had it open and adjusted some info but had some random chrs on one line, so yea this crashed the app.. prob shouldn't do that, but if your seeing something similar maybe look in your config..

selling 100$ aws amazon web services credit-code
pm me with offers Smiley

I am not sure if it works anywhere else other than your own account. If it does - I am dead wrong! and would kick myself for turning down a similar offer earlier.

Sounds like sieving has some kind of diminishing returns. However, does the returns for the primecoin mining overall scales more or less linearly with computing power (e.g., same architecture, higher clock speed)?

Quite a bit, I wouldn't dare to speculate on a quantitative figure. At least a few blocks a day on average. Question is, can you make a return on it, since it looks like (based on the the OS, W7?)these CPUs would be running in 'desktop servers' that you probably purchased.

i have a 5639 dualsocket server , running ubuntu 12.04 amd64 primecoin-hp10 
and here are my results :
primecoind getmininginfo{
    "blocks" : 138481,
    "chainspermin" : 46,
    "chainsperday" : 3.77730295,
    "currentblocksize" : 1000,
    "currentblocktx" : 0,
    "difficulty" : 9.82679260,
    "errors" : "",
    "generate" : true,
    "genproclimit" : -1,
    "primespersec" : 3931,
    "pooledtx" : 0,
    "sieveextensions" : 6,
    "sievepercentage" : 10,
    "sievesize" : 1000000,
    "testnet" : false
}
in comparision here is hp10 on cent 6 , dual 2650s :
primecoind getmininginfo{
    "blocks" : 138482,
    "chainspermin" : 55,
    "chainsperday" : 6.34229883,
    "currentblocksize" : 1000,
    "currentblocktx" : 0,
    "difficulty" : 9.82675713,
    "errors" : "",
    "generate" : true,
    "genproclimit" : -1,
    "primespersec" : 6681,
    "pooledtx" : 1,
    "sieveextensions" : 6,
    "sievepercentage" : 10,
    "sievesize" : 1000000,
    "testnet" : false
}

you can only overclock it in single cpu configuration , not dual socket ! , what do you mean does it worth it , if it is 90$ a month , with current prices , that's unlikely to return the investment . if you are purchasing it , do you need it for any other reason ?

thanks
but my question is : L5639 costs about 90$ ,dual 1366 socket motherboard is about 120$
is it worth for mining XPM ??
i think that i only purchase L5639 for mining purpose  Grin

The difficulty will increase to 10.0 soon. Not easy to make a return on current price.

yes,L5639 works fine on 1366 desktop motherboard,you can overclock it easily

I don't know of any dual socket motherboards besides the SR-2 that have overclocking features. They're all server boards.

got my first block on hp10 with stock settings after 3 days, mining on a core i3 with -1 idle priority (usually, when I leave the computer, I find a block). but i'm keeping my PC turned on 24/7, not doing really well.

Then consider yourself lucky. I spent three days without a block on an i7 3770k.
I have given up for the moment.

I have gotten improved performance since the hp10 update on my desktop. I got two blocks on the 26th and one tonight on my 3930k. Before that I was just getting a block every four or five days. At the same time, it could still be a lucky streak since I have had mixed luck mining on it previously.

Don't just trade, get paid to Atomic⚛Trade !!!

That's a great sample size and statistical analysis you've provided there. It could've easily been due to variance (luck) alone. I wouldn't read too far into it.

Without any way of benchmarking I am not sure how one would answer this.  All we have is chains per day (cpd). Those appear to scale linearly with cores (up to 12 at least) on the same architecture and would increase with frequency but no idea how much (i.e. is 3.2 to 4.5 10% faster or 40% faster) .
