Looking to find the threshold..

[omegaaf]

I am a bit of a mathematical mind, and I wish to find the threshold/point of intersection where an average Mh/s / Gh/s to realworld currency.
So.. how many hashes does it require to make 1 bitcoin?

And yes, for those who are curious, I will post the equations and graphs after I am done.

It takes on average (difficulty)*2^32 hashes to solve a block.
A block is worth the block reward (currently 50 BTC + <1 BTC in tx fees.

Thus avg hashes per 1 BTC = (difficulty)*2^32 / 50 BTC.

You can't compare MH/s (which is a rate, MegaHashes per second) to BTC (which is a fixed amount).

One involves time.  You can multiply MH/s by 1 second and get hashes in a second and thus the BTC in a second.
More usefully you can take the MH/s * 60*60 * 24 to get the hashes in one day and then determine the avg BTC earned in one day.

Your accurate math strains my brain

At current difficulty, it takes ~52,000 shares to make 1 BTC at BTCguild, which charges 5% for PPS.

To make 52,000 shares daily, you need ~2,650MH/s/24hours.  Hope this helps.
