How to calculate the number of coins in circulation

[JackomoLight]

Hi all! Just wondering how can I calculate the number of coins in circulation for any crypto-currency like bitcoin, litecoin, dogecoin, quarkcoin etc. I am trying to do this programatically. Any help much appreciated!

I think you can get a lot of coin names by filtering all the [ANN] and [Pre-ANN] thread titles on this sub-forum and extracting the *coin string.

How about looking to coinmarketcap or to an block explorer of each coin (requirement to get on coinmarketcap)

He doesn't need the names or the types of coins around , but the numbers of already mined amount of each coin btc , ltc or etc.
You can get that data from each coins blockexplorer , or parse coinmarketcap and trust their numbers.
