the easy-of-use factor did it for me, is there another platform you'd recommend that has lower fees?

GDAX has much lower fees, but it's not as easy to use. You can also screw yourself up if you don't know what you're doing, as on any exchange. But if your goal is to learn crypto trading, it's a good place to start.

Thanks, I'll check it out. Also at what point do you pay fees? When you sell / exchange back to dollars? Yes, here to learn!!

There are no deposit or withdrawal fees, just when you trade between currencies. The amount depends on if you place a buy/sell order at market price or some other amount. See this link for info:
