Hi there!
Im running a little Office with some employees. Since its a little Office, all power costs are included anyway.
Lately i thought to do some bc mining while the computers are not in use (~15hrs a day).

Configuration(s):
6x i5-3570K @3,40Ghz + Radeon HD 7950
1x i7-2700K @3,50Ghz + Radeon HD 7970 (my boss computer Smiley)

What i've read so far: If i would do "single mining" with each, it could take several months to unlock any 25btc key.
So i thought about doing pool mining with all the computers.

I compare some data from https://en.bitcoin.it/wiki/Mining_hardware_comparison to get the total mh/s:
6x HD7950 = 6x500MH/s = 3000MH/s
1x HD7970 = 650MH/S

Means a total of 3650MH/s with all my office computers.

Now my question: I did read that pools usually pay you for your "work", means by your MH/s, correct?
So would it be worth to add each computer to a pool?

Which pool would you suggest? How much would i get in average by running each machine for 15 hours a day?

Im new to bitcoin, its somehow complicated since its "very different" to anything i've seen so far.
But i want to get into the boat Smiley

Please help me and give me some hints, i fear im absolutely lost without...

BitMinter offers BTC mining and NameCoin mining at the same time Wink

Just my 2 cents

Bitcoins > You.

Thanks for your reply.
However, im very confused by "NameCoin".

It says (on default stuff) that i could mine monthly:
B22.02   $51.81
within ~8hrs and all my computers.
So about 16hrs would just be the double, ~103$ monthly.

Since the value of BC has raised up to 110+something yesterday, these numbers dont really fit.

So; why it says B22.02? B = BC or BTC? Confusing!
Also; doesnt the reward usually depends on the pool? Or does this NameCoin site calulates with "single mining"? http://beta.ivc.no/bitcoin/namecoin/

I would definitely suggest you look into Slush's or BTC Guild pools.

I would also suggest you get the permission from your employer to run the bitcoin mining on the machines.

Guilds are what i am looking for!
Since the chances to get any reward by some computers is almost zero, i rather use their work to get some "fixed" rates from those so called guilds.

I would use run the mining only outside of office times, there is no harm at all.
Also i do not need permission to use "computers of my employees", since its my little office and i bought those computers.

Can you suggest any guild?
Computers will run 16hrs a day for mining, 3650 MH/s in total.

I want - at least - the income of our coffee consumption Grin

There are several pools around you can mine on. I have had good experiences with https://deepbit.net/

Well, so DeepBit works like this?
You register an Account, add your Bitcoin Number in it.
Then with parameters you start any Mining-Tool, add your eMail and Password from DeepBit Account - and simply keep going?

Which of the 2 available Options is better (personal experiance would be nice):
- Pay per Share (What i understand: You work and work and work, get reward for any work you do, doesnt matter if successfully or not)
- Proportional (If you helped to solve any block, you get a percentage of the work you did on it; "only" rewarded on success)

I wonder how hight the proportional selection would be, after all i guess you would help to solve good blocks once out of 10 times.
Which would mean, if a 100 people are about to solve one, you would get *0,01 of it, maybe *0,02 if your work was double as high as all others.

The other option states: "Pay per share: 0.00000336030223163 BTC per every submitted share"
How many shares does a client usually submits per hour? I have no idea!
Actual chart: $145,50 (what the $%)

So DeepBit gets me 0,00049$ per share.
That means i would need to submit like 2050 shares for ONE dollar.

Any Data from Experiance? Any Numbers? Suggestions?

You have enough computers to try both options.  Join the pool, let your computers run for a few days and you'll see which options works out better.  Or maybe there won't be much difference.

I start to think that absolutely noone here ever used bitcoin.
No numbers, no experiances, only replies i already know about.

Im looking for Numbers out of Experience from other users, not for Links i already did post by myself, which you had known if you would read this small thread before posting useless replies.

**Update
Ive testet it now on 1 of the computers:
~ 15 Minutes (2-3 breaks, guiminer did fail sometimes >> timeoits)
Means about 100 Shares i did send.

Those are worth 0.000336030223163 BTC
0.000336030223163 BTC are worth 1/2975 BTC, so $145,50/2975 = $0,049 per 15 minutes.
>> Per Hr = $0,196
>> Per 16 Hrs = $3,136

So in 16 Hrs i gain bitcoins worth $3,14 with one computer.
7 Computers then would generate about $21,95 per day.
>> Which is an average of $658,56 per Month - or - 4,52 BTC
Calculated with $145,50 per btc (if i got it right)

THOSE are numbers out of 15 minutes experience, i search for longtime experience.

I can theorically make one BTC every 30-35 days with 450-500MH/s of power (assuming the pool doesn't get stuck on a day-long block). That can give you an idea of how much you can do with 3500MH/s.

THANK YOU!
Since this fits with my little 15min calculation, i will go for it  Smiley

yes, i would highly suggest joining a pool. they do take a fee (~1-5% depending on which pool you join), but you get a steady and predictable payout. you can calculate approximately how many BTC you would make here: http://www.alloscomp.com/bitcoin/calculator

with 3650 MH/s you would make 0.27 BTC per 24 hours

keep in mind that this is calculated for the current difficulty. The difficulty adjusts every 2 weeks based on the total network hashing power (to ensure a predictable supply of BTC) and it is currently rapidly increasing (chart) due to ASIC deployment, so you should expect to make less BTC per day every 2 weeks (every 2016 blocks to be exact)
