Is it worth mining bitcoin with CPU?

Zero, no, sorry.
The network is too powerful for a single CPU to have a chance.

[Sniar]

You would be lucky to get even a cent with a CPU at the current difficulty (Even with free power)...

[Shattered]

Without question, the answer is no.
You would literally be better off standing outside trying to catch nickels falling from Mars.

Definitely not worth it today. It used to be that CPU mining was worth it, but that was back in 2009 and 2010. By late 2010, CPU mining became obsolete because GPU mining was developed. Then in 2013, ASICs were developed which made even high-end GPUs obsolete.

To put it into perspective, your CPU would be capable of ~6 MH/s while consuming 80W of power. A single USB Block Erupter which can be bought for $8 used on eBay can achieve 333 MH/s while consuming 2.5W of power. Even so, that Block Erupter would only earn you ~150,000 satoshis per year (worth about 30 cents) assuming that the difficulty doesn't increase.

I'm getting about 6,000Khash/sec with a 6-core, 3.33GHz Xeon Mac Pro.  I tried the -4way switch but it didn't seem to help.

Its not worth mining any coin unless the coin is new, from a joe pov.

A few satoshi, CPU mining is a thing of the past. GPU took over CPU mining late in the 2010. ASIC took over GPU at around 2013, the smallest ASIC miner, USB block erupter can mine Bitcoin more efficiently in terms of power consumption and space requirements. You can try mining GPU and ASIC resistant coins but there is no guarantee that the price will crash and you would lose your profits.

Perhaps ethereum whenever it finally gets released can be mined on a cpu.

[Bizmark13]

Yeah, I forgot to say that it should be possible to mine CPU and GPU mineable altcoins and then convert them to BTC using an altcoin exchange such as Cryptsy. You wouldn't be mining Bitcoin directly, but you'd earn much more BTC this way. Here is a list of CPU mineable coins:

And here is a site where you can compare the profitability of mining different coins:

Don't bother mining any coins that use SHA-256 (e.g. Bitcoin, Peercoin) or Scrypt (e.g. Litecoin, Dogecoin) since these are dominated by specialized ASIC hardware.

I used to mine Primecoins on my two CPUs. Was fun to get the blocks, I think the reward was almost 20 then. Then the difficulty kept rising and I shut them down when it crossed 9.

I doubt there is any profitable enough CPU coin these days.

[fryarminer]

I had to check the date that this was posted. Twice.
Excuse me now while I got outside and wait for nickels to fall from Mars.

Look under the altcoin annoucement page. You will have better luck mining newly launch cpu coins and then convert it to btc rather than mining btc directly, which basically yield nothing.

Mining bitcoin. Nada.
Mining altcoin. Sure

[nextblast]

Good rig... but not for mining btc, unless you could build a time machine.

[dsattler]

Check out the "Monetary System" (MS) of Nxt, there are some coins which can only be "minted" by CPU.

Here is a link: http://nxt.org/about/monetary-system/

[elephantas1]

Good rig... but not for mining btc, unless you could build a time machine.

yeah the difficulty increasing even though the price dropped hard its totally not worth mining it

[cakir]

You can mine XMG and sell them for BTC.

[tss]

no sorry.  you're a few years too late. 
what does it work out to? .2 cents per month?

[elephantas1]

You can mine XMG and sell them for BTC.

yeah you can but you will get cents for it which will not cover you electricity fees

[wadili89]

you will be lucky to buy a lolipop after a year of mining probabely you are 4.5 years late do visit hardware section to buy a miner to get start

[bitwarrior]

You might try using your CPU on mining bitcoins sing this link thread https://bitcointalk.org/index.php?topic=929196.0
It can get you some small amount of bitcoins but it will not amount much.

You can best try fetching free bitcoins from faucets instead than mining bitcoins using CPU. Others are suggesting by mining other altcoins which is quite possible and then exchanging them for bitcoins.

good luck!

No and it isn't worth with GPU too. Forget btc mining, those days are over. :/

[nwfella]

Absolutely not worth it.  Unfortunately insofar as mining bitcoin is concerned you are literally several hardware evolutions behind the times.  Even the next two evolutions (GPU's followed by FPGA's) are absolutely not worth mining with and if you take a look at the Mining speculation forum you'll find that even asic's that are over 3 or 4 months old are pretty much out of date and not expected to ROI at present.

For mining btc? i think 1-10 satoshi
if you want to mining, try altcoin

[ronaldo40]

better use of mining tool, because the cpu is not intended for mining, fear not last long. but if the results via cpu comparable (large), could possibly be considered CMIIW

[Bitdonator]

Forget about that, you cant earn Bitcoin with CPU mining...
you can only loose money on electricity bill.

Better option for you is to find profitable CPU altcoin, and exchange
mined altcoin for Bitcoin....

or simple visit faucet websites... you will earn much more than
with CPU mining

faucet list:

[kwaasteniet]

How much money will i make in a day with this cpu:

Probably 1 sathoshi.
Don't waste your time and electricity with CPU mining. You can better visit faucets with that CPU. With this set of faucets you can earn +/- 20,000 satoshi/hr. It is not much but 20,000 times better than with CPU mining.

[pooya87]

because of the current high difficulty you can not use cpu for mining bitcoin you can take look here for some info https://bitcoinwisdom.com/bitcoin/difficulty

[totoy]

  go mine wth your cpu 

[Dread Pirate Roberts]

you should buy a special miner to mine bitcoin as fast
if you only use your pc or higher part it will not helpfully

[Anillos2]

Look at these graphs:
http://bitcoin.sipa.be/

In 2011 (December) CPU mining gave very few mBTCs every day...
Now It's even slower.

If you like to mine, try another coin or purchase ASIC hardware.

[redsn0w]

How much money will i make in a day with this cpu:

No , obviously no. It is not "suggested" and profitable mining bitcoin with cpu. I suggest you to avoid it....

[MEPHuk]

If you want to mine with your cpu, check this post out (might be a bit out of date, but will give you a general idea) - https://bitcointalk.org/index.php?topic=267664.0

Hope this helps
