Current payout rate: 0.00173091 BTC

Current difficulty: 25997.87992881

0.00173091 * 25997.87992881 = 44.9999903475765171

So it looks like the site pays out 45 of every 50 BTC, keeping 5 BTC or 10% for the site operator.

I think it is a great service to provide a fixed payout, and I can understand the need to keep a percentage given that you are effectively insuring against variability of block finding success.  But it is important to be upfront about what you are charging for the service.

umm sorry i am a bit new to bitcoin,

so how exactly do we get paid per hour ? or when ever we get a block? if its when ever we get a block - wouldnt it take 2 months or so :-(

is the hash submitted automatically? im sorry im a noob i know
thanks for explaining :-)

o wow thanks so much for the help!!

another (offtopic)question - are u accepting lindens for bitcoins :-)

i can try  

Alice runs a pool.
Bob's miner gets 500khash/s, which earns him about 1share every 2hours.
Bob's miner is connected to Alice's pool.
Alice's pool is that big, that it creates ~1block per hour.
Bob only gets a share of half the blocks created by Alice's pool, although he's connected 24/7.

Great - i sent you a pm - ty so much for answering my questions. Cant wait to do a exchange with you!

it's fine running multiple miners with a single address.
your choice to use a single address, or one for each miner.

"Take" is actually a bit of a misnomer, as the server only gives out.  What happens is that the server pays you 90% of your statistical expected return, and keeps the actual return, which could be anything depending on luck.  You might lose a few percent over your expected value due to stale blocks resulting from network overhead, which is how BitLex ended up with 87.8% return.

At 620Kh/s, you will solve a block every 5 years, 37 weeks at the current difficulty.  Since difficulty will keep going up, you are likely to never actually solve a block on your own.

However, your expected return per hour is 50/50027, or .000999460 BTC/hour.

Mining at BitPenny at the current difficulty, you will solve one share on average every 1 hour and 55 minutes, 27 seconds, earning .00173091 BTC, the equivalent of about .0009 BTC/hour.

You could withdraw your first .01 BTC in about 11 hours and 7 minutes.

I like your service, but please, don't mist the reality that earn 50BTC against your pool is like mining standalone with higher than current difficulty, something around +10%. It is absolutely OK, as you take a risk of block variance and must be ready for unlucky times, but it is real cut off.
