Like geographically or if it is from fiat or alts. Also if it is large or small orders etc?
You asked a good question and it deserves a good answer. BTC inflows are dominated by three economic actors at the current time: Japanese Yen, US Dollar and Korean Won. Please note this only reflects public exchanges volume, so this will not reflect any OTC trades that may transpire. I looked at the data myself and feel the numbers are much too small for BTC buyers transacting in EUR, MXP and CHF.
