<p>We know the network adjusts for 25 new bitcoins per 10 minutes.</p>

<p>Together this provides enough info to give an approximate answer to your question:</p>

<pre><code>hashes per bitcoin 
= (network hash rate) / (25 BTC per 10 minutes)
= (180 * Th / s) / (25 * BTC / (600 * s) )
= 180 * 600 / 25 * Th / s / BTC * s
= 2,700 Th / BTC
= 2,700,000,000,000,000 h/BTC

What does the 180 stand for?

That is read from the charts I linked to. It is the current network hash rate in terra-hash-per-second, as the charts show this number continually changes as miners come and go.

Thanks! I think I have to dig deeper into the function of BC to understand everything!

@powtac remember this result changes every 2160 blocks (roughly two weeks).

The current network hash rate is no longer "180 * Th / s" it's now "14000 * Th / s"!
