[XPM] [ANN] Primecoin Release - First Scientific Computing Cryptocurrency

[willittobe]

Anyone know offhand, if XPM is worth mining on say, 5 celeron G530s (~900 PPS each?) at the current price, taking into account electricity? Or perhaps there is a calculator for this?

Solo or pool?

Solo or pool?

Either- I suppose the big difference there would be variance.

You'll have to tell us your electricity rate, my crystal ball is broken.

[atariguy]

In my opinion, XPM is only worth doing anymore if you've already got a computer sitting there on but not fully utilized.

Heh, yah. And those aren't cheap to fix.
Just about .10 / kwh - usd

GPU miners, so probably meets that definition.

[dreamwatcher]

I have started testing the new server environment.

As a result the test Primecoin Explorer(and eventually the release explorer)

Has moved to its permanent address:


xpm.cryptocoinexplorer.com

or

I am roughly at break-even against electricity with my older Core 2 Duo and equivalent Xeon CPU's. However I pay 3x more for electricity than you. So you are off to a good start. If you have newer CPUs like i5 / i7 or any Xeon from the last 3-4 years or AMD equivalents then you should be well past break-even.

I have an i7 running and it's only found 2 blocks so far this month.

[FoldingTime]

I have an i7 running and it's only found 2 blocks so far this month.

Sounds about the same as mine.

[ReCat]

I started mining with my rack server and I found 1 block on the second day.

[Pentel]

With my i7 running only 5 hours per day on average.  I got 3(Three) blocks this month(so far) and 2(Two) last.
So yes about right.  

EDIT: 4(Four) this month.

End of the day, it's luck more then anything else, I mean I got 2 block's within 10 minutes of each other, this month!!!!  Never happen again to me!

Is there a public display of the total Primecoin Network "Hashrate"?

Maybe this is the closest you're gonna get right now:

When you guys talk about your i7's, keep in mind that the product range is huge and wildly varies in performance. Might be best to give the model and frequency.

For example the Intel Core i7 610 @ 2.53GHz is about 20% as fast as a Intel Core i7-4770K @ 3.50GHz and about 1/7th as fast as a Intel Core i7-4930K @ 3.40GHz.

There is no simple convertion between diff and hash rate estimate like there is for SHA-256 or scrypt.

It might be possible to estimate (with a significant % error) an 'equivalent-FLOPS' but keep in mind that mikaelh has mentioned that prime mining is mostly integer maths operations not floating point ops. So I think such a metric would be pretty useless. I don't know enough about those metrics to say if there is even a good way of measuring and comparing integer operations.

A better idea might be to select a CPU that you have, consider its chainsperday value, convert to an estimate of the real probability of finding a block assuming zero variance at a given decimal difficulty value eg. 9.86:

0.8 * (1 - 0.86)

 and then work backwards to figure out how many of those CPUs in total the network is equivalent to.

Why do you think Primecoin slumped down so deep this morning?  
 I was buying last week when it dropped below 0.25 becuase I thought it was funnny cheap but when I looked at the price this morning I was shocked. It slumped down without any correlation to bitcoin or XPM mining difficulty (or am I wrong?). How deep it could decline further??

There's not a single reason why it would stay this high. A month from now we will be at 0.0002 or something, mark my words

[Trillium]

Part of the reason is mcxFEE on mcxNOW. As the market price of 'FEE shares rises people are selling XPM like mad to get in before it bursts. I believe eventually it will stabilize and the market will return to slightly higher XPM exchange rates (but we're never going back to >0.005, I suspect).

[markn]

I think XPM was always overpriced - it shouldn't be that expensive if you can mine it for much cheaper.

But the novel nature of it made it like a lot of noobs weren't able to mine it with a few clicks. There are now many documented ways to mine, including pools, so it's over.
I am now pondering selling my last XPMs, which I kept it case the price ever went up... However renewed interested in a GPU miner (with development financed by big GPU miners) could reduce the supply and thus make it worth a bit more.

I am stone sure it grows back to 0.005 or 0.006 because XPM proved to be strong coin. I wonder how someone couild sell their XPM for current low price only in order to buy expensive MCXfee "stocks" which seems very overpriced now.
I am buying all cheap XPM with all my bitcoins because I believe demand stays at the same level but supply could stop suddenly today or tomorrow and it will cause evaluation at least to 0.005.
I was scared to buy MCXfee for 0.5 BTC because I thought its already too high and for 0.75 its even more overpriced. Why I should buy such "stock" for ONE bitcoin when shares from exchange would generate me only a fraction of % of my invetstment If MCXnow was like bitstamp with licence to exchange coins directly to fiat it would be anything else but MCXnow is not so famous.
However I wish all profits to people who bought MCXfee for 0.1 btc becuase it was risky investment, the price could also go the other way and could drop to 0.01 btc. (what I expected)
