For a long time, Primecoin was 'the' CPU coin along with a few others.  But, I haven't really seen much as far as the 'most profitable' cpu coins to mine; its all ASICs and GPUs.

Are there any coins worth mining with just CPU?

I think none? Maybe I'm wrong but it can't be profitable. Try to find here something that will suite you (http://www.coinwarz.com/cryptocurrency).

That's what I mean - there have been a lot of development around 11x, 13x, 15x for GPUs and ASIC developments for SHA-256 and Scrypt, but what about CPU mining?  Is it just completely unprofitable to CPU?  Or is there an algo I'm missing?

Edit - Maybe a better way to answer my question is with a question; 'Is anyone CPU mining? And if so, what coin/algo are you mining?'

You will find few and far between.  Most cpu coins are able to be done with GPU's (don't want to say all becuse i could be wrong).  I would do some roi as normally these day's most will run more electricity then you make on CPU / GPU.

Currently GPUs can mine on both SHA-256 and Scrypt so sadly there aren't any CPU-only coins.. Unless someone would like to make one up?

There are other algos beyone sha and scrypt.

Some coins claim they are CPU only, never stopped to verify if it is true or not

Sure there are other Algos but are there any coins based on any other than SHA and Scrypt?

Best cpu coin right now is monero... but it won't last long as someone is developing extremely fast GPU miner for it..

I think it's useless to use the CPU to mine, I fear we are rapidly damaged the CPU, is it better to buy a tool, or use the VPS for cloudmining

You are right it's useless and it can damage your your CPU too if you tweak the settings too hard.

Don't know about profit but u will surely lose ur pc if u mine with it..

Try with the Jackpot coin, it should be one of the best coins you can mine with the CPU at the moment.

Nah, GPU miner is better for jackpot coin..

Theres only one coin that you can mine with cpu and make bank - MONERO.

CPU/GPU mining at the moment is 1/1.  Mine while it lasts..

I used to mine quazar coin since day 1 using my i7 CPU, but then I stopped mining as the difficulty keep rising. More discussion about CPU mining can be found here https://bitcointalk.org/index.php?topic=775193.0

The stupidity of people here who automatically assume that CPU mining will automatically destroy your PC is too damn high.


Running your CPU at 90-95% with decent cooling (i.e. doesn't go about 80 Celsius - and stays in the mid-70s most of the time) won't noticeably hurt your laptop / desktop's lifespan.

XMR was good for CPU until the GPU miner came out. And then the price crashed and no longer worth the hassle mining

I think only Primecoins for CPU mining.  ;D

I've noticed this as well.  And it doesn't seem to be on too many exchanges yet.  I heard that cryptsy couldn't add it because it the wallet address length was too long?!?!


I've been considering mining Primecoins for months - but it seems like the price continue to drop.  Has there been any new development to the coin?  Or is it also (eventually) doomed to the GPUs?

CPU mining is neither profitable nor good for CPU. You would rather get your CPU damaged.

Well, I have several old computers that are 'ready for the dumpster' and I don't really care if they experience any kind of damage.  And with winter right around the corner, I wouldn't mind a small loss for the extra heat.  I just know that cpu mining was the 'new' and 'coolest' thing when Primecoin came out, but now that doesn't even seem profitable.  It doesn't seem like there are any 'popular' CPU coins right now.

So no CPU or GPU mining possible profitably.

There are some CPU and GPU which is profitable but your electricity need to be dirt cheap...

'

Dirt cheap as in free.   CPU and GPU mining is for the nostalgic or college kids that have the university paying for electricity.  The mining industry has matured beyond CPUs and GPU.

I'm afraid you're right - its kind of scary isn't it?  Wasn't one of the key concepts of all crytpo-currency that everyone 'owns' it and was able to mine it?  That way there are 'millions' of peers rather then a few big 'monopolies' that 'controlling' the currency.  Everyday it seems like there are fewer and fewer (bitcoin) miners and most other currencies are following suit...  Is a crypto-world safe with only a few dozen 'big' miners?  I've been pondering it for quite awhile...

Manitoba - 6 cents kh/r.

-20C to -40C winters.  3 vid cards & processor equal a nice space-heater.  Sure keeps my feet toasty, and oh the clocking you can do at -40.

Sounds quite harsh, but unfortunately I must admit that you're right. The only coin right now could rescue home/small time miners is BURST using PoC.

Monero is best for CPU right now right?

There was a lot of other coins with more profitability, but the volume is quite low. BSTY, XMG, CoinShield for example.

The decentralisation was one of the main objectives of crypto coins.
But now its already centralised, in some months it will become a completely centralised one.

But it will remain decentralize for algo that is anti-asic. Hopefully darkcoin would have asic so quick...

The main problem is: as long as you mine using mass produced hardware, of course it will not be profitable.
It's just an implication of how the system works, to be profitable you must have more power than the others and this is unlikely to happen as they have access to the very same hardware, with difficulty equalizing everything.

Back to the point.
What is the 'best' coin to mine with CPUs?

I've been looking at XMG a bit... but I'm not at ease with their "fork every other week" approach.
Following.

X11 doesn't have ASIC soon but FPGA already raped X11 to the finest.

Monero.....

XMG the coin of magi is good for CPU miners, since there is no gpu miners for the algorithm M7M.

Sorry but you're entirely wrong ;)

Can you link me to those FPGA thread handling X11?

Whats special with in for GPU mining?

ahahaha !! this is good!!!

damage cpu used for mining????

maybe GPU VRAM damaged if use it for mining and you use it at 80°C!!!!
but not CPU!!!

  ;) ;) ;) ;) ;)

Currently the best CPU mining coin might be XMG / Magi (https://bitcointalk.org/index.php?topic=735170.3040)

Give a try to BSTY or Slimcoin. They are more professional, IMHO.

Still mining monero with my CPUs. Doing great..

There is no best coin, just look at the options and compare the computing tasks involved in feeeding different kind of coins. Gridcoin for example is a good option to mine with a CPU. Miners can choose BOINC projects to partake from, tailored towards their hardware. This means that payout is in scale, or even the same as with GPUs.

Have a look on Primecoin Ψ (XPM) cryptocurrency, i'm using only CPU miners connected to http://pool-prime.net/ ...

Have a look at Spreadcoin:
https://bitcointalk.org/index.php?topic=715435.0

No Gpu, No Pools, Just Solo CPU mining ftw.

Thanks for sharing, but the algo is x11?

Yup, it's a modified X11, dev calls it Spread X11.
Here's the whitepaper:

And here is a spreadcoin vs bitcoin comparison in terms of features:

Also, here are some hashrate examples:

If you want to fry your CPU then go ahead.

If your CPU would fry with mining, than it's you fault.
No CPU will fry with mining if it has adequate cooling.

Even if CPU has proper cooling but still its not worth mining , profit would be pennies .

only at launch some coin may be profitable with cpu, some designed one that need dedicated code

I'm pretty sure my CPU won't fry at 55C.

Question: 
If there were no asic's or fpga's would Bitcoin be profitable to GPU mine?
If there were no GPU's would Bitcoin be profitable to CPU mine?

Right.  Supply and demand plus difficulty.

i guess i could go both ways with this thread,

CPU mining is ok i guess. But it doesn't cost very much to grab one or two grid seeds.

i bought 2 of them around 65$ for both on ebay. (including the psu. most dont so they can be cheaper if you already have it)

You can buy higher end stuff like block erupter cubes and all the crazier stuff but i decided to start on a mini miner budget.

i use to cpu mine but my quad core got so hot being a laptop it was cheaper to buy asic scrypt miners and a fairly cheap hub.

just my thoughts. Correct me if you need too.. i'm fairly new to mining threw asic my first miner was a set of 5 block erupters haha

Good luck having fun with them. I'm sorry but you're late for the train. You could mine for fun now, but forget making money with this. The gold rush time is over.

It's better then nothing. I still mine riecoin on my Intel Core i7-4770 (with free electricity).

If you are looking for a currency to mine that only has cpu mining supported i would check out pirate-coin go to piratecoindub . com you can mine for doubloons using the qt wallet! They will only allow mining until it cant be done on a CPU/OR GPU anymore.

Does anyone know what the i7-4790k gets mining YACoin now? I need it to do 400 hash/s for it to be worth it...
