Hi guys
I am trying to get numbers on total daily Bitcoin trade volumes, over time (lets say since 2012).
Blockchain.info has a nice chart about that:
https://blockchain.info/charts/trade-volume?showDataPoints=false×pan=&show_header=true&daysAverageString=7&scale=0&address=It shows the averaged trade volumes since the beginning of the year somewhere between $5-25 Million (per day). If we check 30 day trade volumes at
http://bitcoincharts.com/markets/we see:
Bitstamp ~$450 Million
Bitfinex ~$350 Million
BTC-E ~300 Million
Just to take the biggest three here, the total sum over 30 days is about $1100 Milllion / 30 days = 36 Million per day (real values are probably higher since I just counted the first three exchanges). These numbers are roughly matching what you get if you check each individual exchanges website and add the numbers. The problem is that these numbers are significantly higher than the values in the blockchain graph. In any case it means that blockchain.info is not displaying "USD trade volume from the top exchanges" as they claim.
Am I doing anything wrong? Could anyone provide me with a data of actual trade volume over time?
Cheers
