Ndax vs Binance

I read Binance has a 0.1% Trade fee making it one of the cheapest, Ndax has 0.2%. Both have a crypto withdrawal fees of about $20. My intention is to buy 25K of BTC, so I want to know whether to do that at Ndax or Binance. I am looking for the absolute lowest amount spent including crypto withdrawal fee, trade fee, spread, etc... I am leaning toward Ndax, because Binance didn't activate my account even though I signed up, gave my email and never received the activation code despite 2 attempts. So anything cheaper than Ndax for large trades?
