Believe it or not I still be Laptop CPU Solo mining and usually end up with a few of these:

PROOF OF WORK RESULT: false (booooo)

But it's just for fun while I'm working on the computer. You never know you could get lucky and get a nice surprise.  ;D

Please don't do that, you are spoiling your laptop and the speed is pathetic..

CPU mining is ok but what coin are you mining?

I am, but not using laptop as the heat go as high as 90C......

I'd rather buy lottery ticket with electricity costs

Actually CPU mining is the most profitable out of all 3 category. ASIC, GPU, CPU.... of course you need to know what you should do with the CPU mining and not just mine BTC directly...

Huh?

Solo mining BTC at 1.2 MHash/s

I'm currently mining Protoshares on CPU. It's quite profitable actually.

I still CPU mine alt-coins like HBN and IFC because I have the computers on anyway.  The other scenario I have is where I'm GPU and ASIC mining bitcoin on a machine and want the CPU to do something instead of just sitting there.

There are profitability calculators out there you can use.  But don't expect to make more than pennies a day per machine even with the most profitable alt-coins if you are just cpu solo mining.

I know what you can do!

Go use your CPU here:

Make sure to include the referral by IPU077019 part.  Do not deviate off course or it owns my referral link , which would be bad, since  it gives you magical powers

People are mining Protoshare with CPU and make decent income....

Can you please explain more?

I mined this coin from launch using my fx-8350 and a phenom II x4 from launch solo then later got free trials of windowsazure and ocean to cloud mine via different pools, made myself around 4BTC in the last week but the difficulty has skyrocketed and I suspect the price vs BTC won't continue to rise as it has for much longer so I'm out now...... I'm sure there's still money to be made but you could have missed the boat

I'm mining betacoin with my CPU's at the moment hoping it will hit an exchange at some point.

All this time and I only get one referral?  Sigh.  My i7-960 makes about $1.50 a day at ipuservices

Care to expand on this?  What figures?

I still do CPU mining as well as ASIC and GPU mining.

For CPU mining, I am running 3 x Intel Core i7, mining primecoins.

Where to exchange ProtoShare to USD?

Me and I still think that CPU mining is more profitable then any ASIC on the market...

I am and the reason why I am doing CPU mining cause it is profitable. YES trust me, only if you know what you are doing....

What are you mining though?

this

You can find answers all over the forum, Protoshare is one of the best CPU coins right now....

after a quick search of their forums

Want To Buy  PTS 2000PTS  @0.0013BTC

this was posted today & closed, so apparently got filled.  according to the post, at that time it was equivalent to $9 (i guess more now since bitcoin price is up)...  so maybe 1/2 a cent?

i think that's probably less than the $1.50 I can get from other place

i recall having all my servers running protoshare mining on that first day and got 2 orphans and 5 stales... which would have been...  350 protoshares..  this in about two hours.  i imagine the block difficulty is a lot higher now, probably don't get all the orphans and stales anymore either, but, still..  i fail to see how that's profitable if you pay for electricity

Big question for me: will the GPU miners make a comeback at $1000 with 600 million difficulty?

According to this thread (https://bitcointalk.org/index.php?topic=281279.0) they're back in the game above $1000. For about 10 days  :D

Still, makes me think. If the price rise can keep driving the profitability of GPU's back above water, there are alot of GPU's out there... and a vastly more aware/informed public re:Bitcoin price direction and US congressional hearing etc etc. Hmmmmm..........

i mine sometimes for fun but its worthless atleast for me.

I am also using CPU mining (for the second day only, so very new), for mining litecoins.... but results somehow fails to come.

I use 7 of the 8 cores of my AMD FX-8320 (overclocked the turboboost to 4.11Ghz) to mine for primecoins since my protoshares client can't find any peers to download the blockchain...

i can assist with that

use addnode=5.9.24.81

oh, it took me about 15 minutes to fix

had to download some new version

primecoin

To answer the question, people with free electricity and adventurers

I too am mining Protoshares with my CPU and have made decent profit. I have been mining since day one though when the difficulty was really low.

Who ever start on the first day profit the most, I wish I started on first day just like bitcoin..

I was mining on day one and all I got was a bunch of stales and orphans... but even if those had gone through..

Where are you selling these for a decent amount?  Is the price higher than the 2000PTS  @0.0013BTC   I quoted before?   If not, I think quarkcoins are even worth more than that..

is it profitable to mine protoshares?

It was, now it is borderline.  I am finding Quarkcoins profitable.
Look for the $100 amazon deal in the alts forum and anything will be profitable until your $100 credit is used up!

I only got 0.01 pts after mining for a day

LOL are thoose ppl who are still mining with CPU

It is profitable, but only if you know what you do and with low electricity costs.

wel explane how to do that would be nice for everybody who wants to get started right away  :)

Lol
It will probs just hurt your computer and cost you alot in energy

Check out pts and primecoin..

I mined a few PTS over the past few days, but i haven't even calculated wether it was profitable. What's the price for pts right now?

What are the alt coins that are still profitable to mine in CPU?

primecoin and quarkcoin are cpu-speicific coins and cant be mined any other way save cloud servers.

Primecoin is a good way to mine with the CPU (and exchange for BTC). It is quite profitable compared to mining BTC directly.

started with cpu mining yesterday, found a primcecoin block in 20 hours, feels good

They say that every little bit adds up  ;D I heard that CPU mining is best done collectively on work computers that sit powered on and idle.

+1

Maybe is, but isn't that the GPU mining is more profitable than CPU?

Youre better off using your laptop to mine something easier, like litecoin (still not that easy, or an.other crypto) which you can then exchange for btc if needed.

check out coinwarz to find the most profitable scrypt coin.


 ;D

I'm currently mining Quarks on the CPU. Using droplets from Digital Ocean to make a better profit. Just going to mine a few to keep it in a wallet and hope that it gets big one day.  :D

very little can mined

Less than a year ago I mined LTC with CPU. Now the coins I mined back then are worth a lot more than the power costs! So if you mine some low dif coin and hope for the price to rise it could still be worth it.

Started mining it today on my i5 760 desktop :)

Please don't teach people bad speculation.  It never makes sense to mine at a loss.  The only to mine the actual coins at a loss would be if you cannot buy them (ie have no access to exchanges).  If you think the coins are going to go up, then it would be cheaper to buy them.  If they go up next year it doesn't matter whether you mined them or bought them (other than maybe a feeling of satisfaction).  If you mine at a loss you're spending more $ than you need to (assuming you have access to an exchange).

My computer is AMD A8-3820 APU
Is it a slow cpu to mine?

I am, on the bitcoin testnet.  Since the difficulty level is just '1', cpu is still sufficient.  We need funny-money to test our bitcoin software, etc.

I'm using testnet-in-a-box (d/l from git) and it's running fine; only problem I have now it trying to get my money - it seems to not be making it into my wallet, I think because they are still in either an 'unconfirmed' or "immature" category. 

I'm still doing it on my work computer while I'm just sitting here at work.  Just getting a small steady alt coin stream of little cash.  Why not I figure

They don't exists ! Perhaps it is more appropriate to say: people who steal electricity
Why to assume such a risk ? Better buy BTC/LTC, wait for a good price, then trade for a nice profit!
It is more safe too!

My electricity bill is a fixed amount per month, so whether I mine or not the costs will be the same.
It's not free electricity but it's not a theft either.

Where do you stay?

Some people live in hotels/motels for extended periods of time. In this case, electricity is included and can be considered a fixed cost.

Uni dorm

CPU mining is still very profitable even though you don't have free energy... you just need to choose the right coin....

So, which one is the right coin?  ???

Primecoin

and pts...

I mining PrimeCoin only if I work on my computer, so I expect it is free because my computer would be on anyway

these days you can start earning a very lucrative business if you have money you can win every time :)

Cpu mining is so last year  ;D

I wonder when people will say that about gpu's...

I didn't know that CPU mining was still a viable option.

Its still not free cause you consume way more electricity when your cpu usage is 100%...

Hey guys .. nice forum post, looks like there right place to post.

Anyway .. lets say you can get a server with 128 cores .. and you mine primecoin at current rates, what would be a good average earnings per day?

Or something like 8 x 8core server. 64 cores.
http://www.ricardo.ch/kaufen/computer-und-netzwerk/server-und-zubehoer/sonstige-server/gateway-8x-8core-2-00ghz-128gb-2tb/v/an740571332/

Its only like 700 swiss francs .. thats around $500 USD i think .. will the machine pay for it self anytime soon ?? :-)

Would it be enough to cover energy cost? 

It's hard coz I can't seem to find good cpu mining calculators.

I like the idea of primecoin or CPU coins, but is idea just going to cost me money?

Thanks guys

You bumped a thread that was over 7 months old, which in crypto terms is almost 3 decades old.  CPU mining more or less ended when XPM has GPUs take over the hash.  I mined XPM on CPUs until Feb, after that it became pointless.

Your 128 core server can't compete with GPUs.  Look at the alt mining subforum and you will find Claymore's GPU miner for XPM.  CPU mining would not even cover power costs (also XPM is tanking in price).

:-) .. thanks for the quick answer .. so basically, CPU mining is finished then.. forget the whole idea ?

What a shame if thats the case, all those cheap 128 core servers going to waste. lol

Well some people have access to idled extra rows of cabinets old servers in a noc, free power and hardware equals time to get creative with mining low diff alt coins.

 ;D

How came people are still mining with CPU. Heck, I wonder why they still are mining with GPU even. If you consider ASIC market right now even a low end cheap ASIC will be a lot, and I mean A LOT of faster than any normal GPU, CPU mining. I don't include situations where you have unlimited resources and  power of course. But if you want to be mining hipster you can still mine with CPU ;)

I cpu mine with an old gaming rig i have. I get 56khs per core, and I have 4 cores. It's not to bad. I mine darkcoin. X11 seems to be the only thing worth mining. ASICS are taking over everything else.

No one,bitcoin

Hi, so do you think that this server might pay itself off anytime then?
http://www.ricardo.ch/kaufen/computer-und-netzwerk/server-und-zubehoer/sonstige-server/gateway-8x-8core-2-00ghz-128gb-2tb/v/an740571332/

I mean, does mining darkcoin pay for the power bill at least?

Not me anymore  8)

Right .. so its probably the power bill that stops it from being profitable, coz 1 good GPU is $600 + and the server I want is 128 cores for the same price.
The hardware costs are about the same. Am I still seeing this wrong?

This is pretty much the only case for CPU mining.  Finding some random altcoin that everybody has lost interest in and consequently the difficulty has dropped.  Of course at that point the coin is to be considered dead and won't even be listed on an exchange.  Those are dead coins, zombiecoins.  Examples would be Kittehcoin and Lottocoin which are now worth less than a Satoshi each.  You could CPU mine those dead things and hope for a revival if the dev puts time into it - basically gambling.

But if you have that much free time, I would make my own scam coin, premine 80% of it like BCN, and then promote the hell out the scam.  Is it immoral - yes.  Is it what almost all the scammy altcoins are doing - yes.

So just curious anybody out there still CPU mining protoshares.  Is it still profitable?

While protoshares may individually worth a lot they are damn near impossible to mine unless you have a botnet or some 500 machine farm.  I used my wife's office computers for a month (i5s) and I think 8 of them made less than $4 - about a penny a day per CPU.  A botnet owner could make money with it, but most botnets could find a more lucrative source of income like hired DDoS - botnets and DDoS are both illegal activities BTW.

I am still cpu mining but profit is dropping each day...

Add me to this list  ;D

Solo mining in the hope that i hit a block and then i will be rich!! :D

Seriously though, power is fairly cheap where i am, so i hardly lose anything!

Good question! :)
Currently I'm mining XPM on CPU. But it's interesting if anybody have better coin to mine on CPU (based on experience not theory ;-)
btw: good CPU coins site: cpucoinlist.com

I've been mining Monero on my CPUs for a little over a month (right about the time difficulty jumped up) and my CPUs are still turning a profit.

I switch off between Monero and Dimecoin when I have some free cpu time. Im not expecting to make much from dimecoin, but I have hopes that Monero might go up in price someday. Either way its only when the computer has to be on and has free cpu time.

Started playing around with CPU mining again (nostalgia from 2012) and was looking at cryptonote coins (Bytecoin, Monero). Using a 12 core Xeon, I get about 135 hashes a second. Some miner on minergate.com is getting 10 kh/s, which translates to 0.05btc a day. 

Other than a botnet personal army, anyone have any strategies on CPU based mining to maximize profits?

What miner are you using? I get 265 H/s from an i7 3770 using Wolf's miner with threads=1/2 of cores (physical or virtual if it has HT). Having AES-NI is a plus as well as running on Linux instead of Windows. But that's just what gets me the best results. Xeons seem to be different to tweak than desktop CPUs. And no, you're fairly limited unless you have a lot of CPUs to work with.

Here's a somewhat useful chart: https://docs.google.com/spreadsheets/d/1MI-ic0Os25hgGUImW54sUIjZY_pUNQNa_W8Se5pRGBs/edit?pli=1#gid=0 (https://docs.google.com/spreadsheets/d/1MI-ic0Os25hgGUImW54sUIjZY_pUNQNa_W8Se5pRGBs/edit?pli=1#gid=0)

I was using wolfs miner. I'll check my settings again too.  Thanks for the spreadsheet link!

I also just saw someone has a GPU miner now too (Claymore)... It doesn't seem like thee CPU-only algorithms last very long.

Well my entry is still the 2nd Fastest single system out there at least on this list. Held #1 for quite a while.

Strato

4x E5-4650 server gives 1534H/s with wolf's miner.

Interesting thing: if run by default (64 threads), I had about 1050H/s.
Running at 32 threads (4x E5-4650 is 32 threads) I get 1534H/s.
So, beware of HT CPU's, and running too many threads!

This has been documented on nearly all CPUs.

I actually get better results running 3 cores on a 4770k vs 4 or even 8.

HT kills returns - and it's best to leave room for overhead.

So if you have 6 logical cores - 12 in HT; best to try 5.

Strato

OK I fired the laptop cpu miner back up, wish me luck!  ;D

I use Claymore's CPU miner on Minergate (http://bit.ly/1l6hUPe) and I'm getting about 260 H/s on i7 4770.

Is cpu mining more profitable compare to gpu?

I seriously hope that you are kidding me right now?
No, it's not even comparable, you won't even be able pay for the electricity used. CPU mining is dead.
(GPU mining is not profitable either btw.)

So they are comparable... profitability of both of them sucks  ;D
