For a study on Bitcoin, I would like to find (or construct) a timeseries of the total value of all Bitcoins in circulation (market capitalization). At least for the last two or so years. This could be quoted in e.g. US Dollar.

Is there such a time series? If not, is there a timeseries with the total amount of unlocked bitcoins, which could then be multiplied with an exchange rate?

Historical time-series of exchange rate:

Source of the data is the "Raw Data" from BitcoinCharts.com.

The raw data of daily "market cap" is available in json

Add &format=json e.g. blockchain.info/charts/market-cap?timespan=all&format=json –  Ben Reeves Nov 19 '12 at 11:35
    
yes, thank you. it could also be taken from this: blockchain.info/charts/total-bitcoins but I was hoping for an easier way –  bquast Nov 19 '12 at 13:35
    
@BenReeves , thank you that is useful. Any suggestions for importing (e.g. R or CSV), do you want to put that into an answer? –  bquast Nov 19 '12 at 13:38
