Am I blind or what? EVERY other exchange I've used has a "Fees" link, usually at the bottom of their homepage.
Here, I can't find a listing of the fees anywhere.
You find all the infomation on any coin listed on Cryptoia on the coin info page on this link - https://www.cryptopia.co.nz/CoinInfo/?coin=DOT
Click on the coin you want, and then click the settings tab for withdrawal fees.
Trading fees are .2%
There are no deposit fees.
