New to mining, some questions

[lucent]

Hi

So I started bitcoin mining this week, was curious what it all was about.
I'm using f2pool.com and cudaminer. I havent done any mining on my own computer but I've done it(doing it atm) on several stationary computers in my school. I currently have 4 running over night in my school. But earlier I had 15 at the same time, but I guess some teacher went and shut them off or something, im not too sure since im home and not in school, probably shut them off because school was closing, anyway.

The miners are running at around 40 to 50.5 khash/s on quadro 2000 graphics cards, quadro 2000 being the graphics cards my school chose because good for CAD work. http://www.nvidia.com/object/product-quadro-2000-us.html link to the gpu.

I am monitoring the workers on F2pool and I see a number "rejected" get increased on all of them, atm around 30 rejects per worker, so around 120+ total.

So questions.

How much is 50.5 khash/s?
How bad is it?
Can I increase the khash/s amount easily?
Is the GPU that I'm using able to use and increased khash/s rate?
Is having 15 workers at the same time with 50.5 khash/s good?

If you think I have misunderstood anything about btc mining from the things I wrote please do tell me, I'm all for learning new things!

stop what you are doing now it is a crime.  you are robbing power for 15 computers and at the rates you get hashing it will take 1000 years to earn 1 btc.

I run a machine like this

a sp20e   it gets 1.4th  or about 28,000   times what you are  doing.  I earn 1 coin in  70 days

Okay so the hashrate is really bad, is it because the GPU's are bad or because I have done something wrong? Feel strange that it would take 1000 years to earn 1 btc

GPU mining is dead, you are completely wasting your time.  A standard miner today does 1TH, or two millions times faster than what you're doing, and that's just one box.  Most people use several miners.

Buy a usb miner, they'll do 2GH and cost less than $20 if you just want to play around.  Or buy a used S1 for $20, 180gh.  Or a used S3 for $100, 450gh.  But the tech you're using isn't gonna do squat today.

And by my calculation 1000 years is much too small an estimate.  I calc that it will take you approx. 127,161 years to solve a block with that setup.

Ah I see. This stuff is fairly interesting and I did kind of feel that what I was doing wouldnt accomplish much, though I didnt realize it was this bad.

I might buy an usb miner as you said

Hey, you're definitely that guy who posted on /r/bitcoinmining about this "as a hypothetical idea", and then promised you would never-ever try it.

Looks like you deleted your reddit account and tried to delete all your posts. Way to cover your tracks, bro.

It is very interesting, I mine just as a hobbyist for now, I don't want to spend the money to buy the gear it would take to turn a profit today.  The little USB stick miners are fun to play with, like the antminer U2 or bitfury nano fury.  Look on ebay, I got mine for $20-$30 there.  The antminer U3 is another fun starter machine, I have 1 and 2 more on the way, they'll do 50-60gh.

Haha interesting but im really not this guy, my reddit account is /u/confusedgrasshopper, dont know if that's gonna prove anything but I can assure you that I would never care if what I did was "unethical" or whatever, just doesnt match my personality  

And while this guy does have a smiliar idea as I already implemented he is talking about implementing them on the startup directory, what I have done is different, I created admin accounts on the computers and set up a script that turn the computers off right before school starts, all this happening while I have clicked "win+L" causing programs to continue while logged out. Same gpus as me but as I said in the original post they are good for CAD.

I have not seen a thread like this for a while.

This is kinda entertaining and it reminds me of some portugese friends that just got into mining.

They set up 200 computers to run on a school and they made nothing from it.

More productive than what my friend did in college, which was to steal a bunch of unused computers from a lab .
