Where can I find historical price of altcoins?

Quandl has some dataset of altcoins but the history is small and unfortunately prices are not updated.

CoinMarketCap JSON API is great but I understand it provides the lastest update only.

I have found on Bitcoincharts a file named rippleUSD.csv.gz but I don't understand the structure. A convertion of the unixtime with in MS Excel (i.e. =A1/(60*60*24)+"1/1/1970") returns the following dates and time but it is not clear if the last column is price because movements in a single minute interval are huge.

Looking at the Market Overiew API I haven't found relative informations about CSV file structure. Sorry my status does not allow me to post more than 2 links

Do you know if there is website where it is possible to download historical price of big cap crypto currencies such as Dogecoin, Bitshares, DarkCoin and Ripple ?

Thank you,

Florent

Is the site still active and has the latest data? – Vivek Sancheti – 2017-07-13T03:21:28.047

I run alt19, which is a free site which offers historical trade data on a large number of altcoins in CSV format. We have data at 15 minute, 1 hour, and 1 day increments.

Thank you Nick, it looks good. I try to figure out how to import these data in R. From what I see there is for each altcoin a chart page that contain daily prices at 6:00 PM within its source code. For example : http://alt19.com/19R/chart_showing_btc.php?shw=1&label=LTC_BTC&source=cryptsy&period=1day

1Site no longer seems to have the data to download. Or I'm an idiot and just can't find the download button... – Valmond – 2017-11-16T13:46:14.300

Great resource mate! If you are part of the project, please consider adding volume to the tick data – tochkov – 2018-01-24T21:12:04.683

http://www.worldcoinindex.com/ maybe? try to ask them at their BTT thread https://bitcointalk.org/index.php?topic=384546.0 or maybe CoinMarketCap if asked privately will provide you with the enhanced API?
