Hey thank you for the links I was able to get good bitcoin data. But I am still trying to find historical prices for popular altcoins like DODGE, LTC, RIPPLE, NAMECOIN, etc. When I opened the above link and downloaded some of the csv files available I found the data a little unclear to me. I saw three columns, the first column appeared to be volume traded on that exchange the 2nd and 3rd column I was unsure of what they represented. For example in krakenLTC none of the columns to me seemed to reflect price of LiteCoin in either USD or BTC in addition their were no dates.
