Interested to find a good resource with all active bitcoins exchanges I am looking for recommendations for good bitcoin exchanges resource that would include info on:
- live/approximate daily trading volumes
- spreads 
- and most importantly traded currencies 

I found this one: https://bitcoincharts.com/markets/
But it is not up to date (no KRW for example) and I couldn't find a way to sort it by an exchange and it is a bit hard to compare traded volumes by exchange because the info is in different currencies.

Thanks,
Tagir
Cryptonator looks like a good start. 
Find all exchanges for a particular trading pair. 
https://api.cryptonator.com/api/full/eth-btc

Then swap out the eth with whatever currency you're looking for. 

Cryptonator says this is all their supported currency pairs (https://www.cryptonator.com/api/currencies) but looks like it includes some dead coins. You could loop through that URL and for each record, input the symbol into the original https://api.cryptonator.com/api/full/eth-btc end-point.

https://api.cryptonator.com/api/full/ltc-btc
https://api.cryptonator.com/api/full/dash-btc
...and so on.

Once the loop is through you should have all pairs and all currencies, or at least all the ones cryptonator has.
