Hi I am looking for suggestions about crypto currencies exchanges that support alternative coins and don't have high fees like Coinbase(I know Coinbase doesn't support alt coins) has. I have a Kraken account but they don't support some of the coins I would like to trade. Please consider security, alt coin support and fees. Thanks
Tux, Polo, Liqui... But you can go coinmarketcap and check the coin you want -> click on markets tab and see volumes.
