The third was cryptopia with 0.2%, but as of now cryptopia is still undergoing some major issues so I don't really recommend using it.
And even you'll try to visit their site, it has a message on it so its obvious that you can't trade there anymore. It may be temporary but no one knows when their service will come back.
However, I would try Binance. This is the best-trusted exchange with the lowest commissions.
Yeah, I reckon the suggestions with Binance. A known exchange and being considered to have the low fee for most of the exchanges. OP out of your curiosity and desire to look for lowest fee exchange, you need to be careful coz' you might fall to a new exchange that has intriguing yet attractive rates.
