i dont see any way that you could calculate that. Dont bother yourself quit now
You may be correct but not quitting yet.
Am trying a node based estimate then trying to estimate a rough volume of production based on that.
As of Nov 1 China has 28.6% of world nodes which may = 28 % APPROX of bitcoin production. Historical monthly data will give a total mined estimate
http://getaddr.bitnodes.io/http://getaddr.bitnodes.io/188/china/Will add transaction volume data from
http://btckan.com/priceand see where if there is a correlation of sorts and see where that leads unless someone can suggest an easier way.(which I was hoping for
)
Also Transactions can be traced .. Im not sure of the full mechanics yet but I assume its to on IP address and the IP address will indicate the Country. I will focus only on very LARGE transactions and large wallets
http://bitcoinrichlist.com/top500 as these should be MUCH fewer... To attempt every transaction would definitely be impossible for me but an estimate /average of total transaction data may produce a close figure.

Basing on locations/ dates/numbers of mining software downloads I can start to give a percentage of mining of those coins in each Country(yes, not totally accurate but indicative if read with other data)
