Sites like http://coinmarketcap.com have multi year price history graphs for Bitcoin and alts. Question: where does this data come from? Exchange APIs offer real time price info, but not the history from which a graph could be made.

It is awesome to have such data like this, very useful! Historical snapshots help a lot with market analysis although cryptos are very volitalie I have shown people before the fluctuations in the market via this tool.

CoinMarketCap has been running since 2013 and one of the only market data sites left standing as I have seen a few come and go!

I used coinmarketcap API a while ago. It offers only history since the point of time the coin was added to coinmarketcap. This brings me to the assumption that coinmarketcap is collecting the history data on their own by requesting the exchange APIs in short timeframes.

They're likely collecting the data themselves and storing them in a database, so over time, they have built the historical data themselves.

I didn't know that coinmarketcap had historical page data, thanks for the link! Would be nice to get better than weekly precision, but it's better than nothing.

Since the requirements for a coin to be added to the site include being tradeable on a public exchange with an available API, it stands to reason that they have a bot collecting the stats from the exchanges via their respective APIs. Essentially, the information on that site is just compiled publicly available information from the various exchanges hosting and trading those coins.

Hmm, seems like that is probably the case. I guess if there was a paid service that had the full data, it would be more readily known?
