Newbie with CPUminer

[lookingforlight]

Hello everyone
I am just now approaching the world of Bitcoin mining; I dedicated a machine to this task, it's an Ubuntu Box with a CPU miner running.
Anyway, I don't think it's working the right way. I configured it to run linked to bitcoin.cz pool, this is my conf file:

Code:

{
	"url" : "http://api.bitcoin.cz:8332",
	"user" : "[myuser]",
	"pass" : "[mypassword]",
	"algo" : "c",
	"threads" : "4",
	"quiet" : "false"
}

And I get, as output, a lot of these:

Code:

...I am afraid this is not working the right way

Grab pooler's cpuminer source (https://github.com/pooler/cpuminer), build it.
Mine litecoins or any other scrypt-based currency.
Sell it for bitcoins.

It must say "accepted" or "true".

It was also my thougth. Only I was curious to know why.

So far as I understand it you'll probably pay more for electricity than the (current) value of the coins if you're CPU mining, mostly because they get harder to mine as more coins are mined and a lot of BTC has already been mined.  BTC might increase in value though which would offset this.  Another thought is that if you mined one of the other types of coins which are still easier to do, and you picked one which gained in value then it could work out very nicely if you held the coins (or traded them up for more), even with CPU mining over time.  As for BTC mining on your PC, that will become less profitable if a lot of ASIC machines come into use around the world because a PC is much slower so the electricity bought to mined coins ratio is worse, even with GPU mining.  There is of course the point that if your computer is going to be running anyway then it might as well be doing something useful.  Of course though I could be wrong, being wrong half the time is a hobby of mine, lol.  If it wasn't then I'd have a lot more BTC by now

You can turn on detailed protocol logging with -P option. It will give you full info on work and shares.

Thanks for your suggestion people, I appreciate all of it

Anyway, after a couple of considerations, I am trying mining Litecoins... obviously slow since is CPU, but hey, is fun

CPU mining isn't quite worth it anymore

Well, some people may have access to spare servers and free electricity)

Even then, I think you have a hard time justifying the mere time and effort it takes to get them started on cpu mining.

It depends on how much hardware is available. I've seen a post by administrator of some university computing cluster somewhere on the Internets (maybe here, on Bitcointalk, I can't remember). He had thousands of CPU cores, large portion of them idle all the time. 10,000 cores give ~50MH/s (for scrypt!) which is about $500 per day! And at least the same worth electricity bill for the institution
