To my friends using GDAX, if you want to avoid getting raped in fees, all you have to do is set up limit buys and sells, its FREE. Even if its a short trade in the market, its totally worth having the order filled a little early, or a little late to save a couple bucks. It definitely adds up. Almost a month on GDAX not knowing this, and having several hundred trades....close to $1000 in fees. Crazy.
