there are only 2 coins that you can cpu mine for (some) profit: primecoin and quarkcoin. as long as they don't offer gpu mining

Do you know if it's still possible to do CPU mining for Litecoin? It seems like there's a lot of talk about GPU mining for LTC, although I thought I remember a mention that LTC was supposed to be less resource intensive than BTC.

its actually the opposite, more resource intensive. a cpu on bitcoin such as the i5 processor i have gets about 5.4 mhps, where as on litecoin the same cpu gets about 4.8 kh equating to a 10% of what it can get on bitcoin. however on scrypt jane, this same cpu gets 50 khs, making it cpu mineable.

That is correct and the good news is coders are having slight difficulty making GPU miners for these coins so CPU should be good for a long time still

To respond to the topic starter's last question (are there still miners that will do CPU mining):
Yes there are. At least the client provided by Bitminter still supports CPU mining out of the box.
However, while still included, it is not being actively developed and hence it will be quite slow.

I tried it once, just for fun, on an Athlon64 X2 3800EE (dualcore 2Ghz) and it did around 300Kh/s.
Compared to Bitcoin.it's hardware comparison page, this is very low and with a good miner it should be able to do around 1.5Mh/s (around 5x faster)
(source: https://en.bitcoin.it/wiki/Mining_hardware_comparison#AMD)

Still, compared to a GPU, it just doesn't cut it.
Even a low power Radeon HD7750 (120Mh/s) will outrun any CPU, even if it's an 8core Intel i7 (70Mh/s).
Then you should consider the fact that a Radeon HD7750 will only draw about 50 watts when running at max, and that is only a third of a Core i7.

It just isn't profitable, that's the whole reason why people have abandoned CPU mining for Bitcoin and Litecoin.

You could mine Fastcoins or another newer coin with a CPU.

Even the question itself is phased out. Sorry you are very late to the party of CPU mining. Try again after you invest a time machine.

If I had a time machine I would go back to early 2009 and bring my laptop along (which incidentily was built in 2009) with my Block Erupter. It would have made all the cryptonerds who were mining back then crazy and me very rich! Then forward to August last year and buy as much AM shares as I could afford (at least 10 board seats worth). Grin

Or maybe go to the future first to see how everything will pan out in the long run. Cheesy

You can use pooler's cpu miner if you would like to give it a go. It will not mine fast but if electricity is free and the computer is on already something is better than nothing. With the Alt-coins you will be able to still get some shares accepted by a pool if you join one.

mistery: blocks are endless?

bitcoins: are limited?? (they have a cap)

someday... something... will happen!

Miners are paid BOTH the block subsidy + transaction fees.

2009 - 50 BTC subsidy + ~0 BTC tx fees.
2013 - 25 BTC subsidy + ~0.25 BTC tx fees.
2017 - 12.5 BTC subsidy + ~?? BTC tx fees
2137 - 1 satoshi subsidy (0.00000001 BTC) + ?? BTC tx fees.
2140 - 0 BTC subsidy + ?? BTC tx fees.

Primecoin was a blast at first with CPU. Lots of fun were had. But now even it is slowing down pretty quick.

Once GPU is made for it(assuming it happens) it will blow CPU away.

No, not really. But you could cpu new coins when they come out

Cpu mining is done. Difficulty is way too high now for it to be viable. If you want to use a cpu miner, best advice is to go for LiteCoin.

CPU on litecoin barely does anything anymore. If you have a CPU, go to primecoin or quarkcoin.
