How many coins exist right now?
With 100k which were premined?
He's prolly burned half of it generating work for mining.
Don't focus on what I already know
On the other hand lets not ignore an facts...
I asked the same question 3 times..
No one is able to answer it.
Each time I get an answer to a question I didn't ask.
To answer your question. The only way to know for sure is to run a tool/script that scans the blockchain looking at the coinbases (first TXout). But, the coinbases also includes the 0.5% transaction fee so, the tool needs to calculate the fee and then subtract that value from the TXout amount.
I made a guesstimate of the KHC monetary mass using a PRNG and the reward/subsidy table shown in the OP. Consider that after the random rewards ends at block 125,000, there will be only 50 KHCs per mined block. The Diff Algorithm is supposed to allow only 1 mined block every 3 minutes on average so, assuming the Diff is doing its job and assuming an equal distribution of the values provided by the Pseudo Random Number Generator, we have:
Monetary Mass at block 1,000: 233,438 KHCs
Monetary Mass at block 10,000: 1,575,791 KHCs
Monetary Mass at block 100,000: 10,536,618 KHCs
Monetary Mass at block 125,000: 12,417,855 KHCs
Monetary Mass After block 125,000: 8,760,000 KHCs per year.
Thank you very much for taking time to explain. Appreciate it.
