<p>It seems like it actually gives the value in satoshis for some reason, but that's not the really confusing part.</p>
<p>What I wonder is if this value really represents the &quot;total Bitcoins in circulation&quot;, or just &quot;total Bitcoins mined&quot;. Does it account for the &quot;lost&quot; Bitcoins which will never again be possible for anyone to use because the private keys are no longer accessible by any human or machine?</p>
<p>If not, is there a source which lets me grab <em>that</em> number? It's pretty useless to know how many Bitcoins have been mined; I want to know how many currently &quot;really exist&quot;, as in, are actually in circulation, or <em>can</em> be &quot;circulated&quot;.</p>

@Prayank Um... You mean the ones mined -- not in circulation?

If you define "in circulation" as "could be moved", the answer is unknownable, simply because there is no registry of people who have lost their keys. That said, there are many coins that are known to be unmovable; I have an answer about that here: https://bitcoin.stackexchange.com/a/38998/208

Does Blockchain.info's "totalbc" API value account for "lost" Bitcoins?

It seems like it actually gives the value in satoshis for some reason, but that's not the really confusing part.

What I wonder is if this value really represents the "total Bitcoins in circulation", or just "total Bitcoins mined". Does it account for the "lost" Bitcoins which will never again be possible for anyone to use because the private keys are no longer accessible by any human or machine?

If not, is there a source which lets me grab *that* number? It's pretty useless to know how many Bitcoins have been mined; I want to know how many currently "really exist", as in, are actually in circulation, or *can* be "circulated".
