For example, Bitcoin Classic Token is traded on https://saturn.network & token symbol is BCT. However if you want to find it on Blockfolio you would need to watch Blockchain Terminal and then set your market to "Saturn Network."
This means your global averages will sometimes be wrong as they are lumping multiple tokens / coins with the same ticker together. coin / token tickers or symbols are not unique in the world of crypto so I believe this is not the greatest approach.
Our API at Saturn Network supports token contract addresses which are unique, this could be a better approach?
Our full API documentation is found here: https://ticker.saturn.network
