Feature request: Support for more fiat currencies than cryptocompare.com offers

[jemilsson]

May i suggest you add support for more currencies than cryptocompare.com offers? It would be really neat to have data for smaller currencies.

This could be achieved through converting the USD or EUR exchange rates indirectly. There are many services for obtaining rates between USD or EUR and other currencies, for example the ECB publishes reference rates for free.. The ECB data is also exposed in a more RESTful way here.

It would be preferable to have an even larger number of currency pairs, but from what i have found there is no free source of this data. Perhaps you could use something like Fixer.io?

Thanks a lot for the suggestion. I'll add to our TODO list. You are also welcome to open a PR.

If i were to create a PR for this, would you prefer me to implement something free like the ECB reference rates or something with better coverage like the fixer.io service?

@jemilsson It's better to begin with ECB. If we want to use also services like Fixer.io, we need to add a mechanism to limit calls to each service.

May i suggest considering the CoinGecko open public API?
You can query a wide range of currencies we support on the website https://www.coingecko.com/en/coins/bitcoin

API calls can be made as simple as https://api.coingecko.com/api/v3/simple/price?ids=bitcoin&vs_currencies=usd,eur,gbp,jpy,cad,chf,cny,hkd,idr,rub,twd and you can append more currencies if you would like to

The API is straight forward enough to call directly, but should you need a Go library, there is a 3rd party https://github.com/superoo7/go-gecko
