GDAX is a great service...basically eliminates the fees associated with trading there.

I recall that when I first joined Coinbase, I used the regular site which did have high commissions. Fortunately, I came across a video that showed me how to use GDAX and that was the same thing. From that point on, I only traded at a market maker on there.

Anyone who is reading this post, if you are Coinbase, you need to do all your trades through GDAX. There is no reason to give Coinbase the fees they charge on regular transactions. As @cryptographic mentioned, there is very little learning curve and most of your operation is done through Coinbase (funding your account, moving tokens around, etc...). The only thing GDAX is used for is to trade. Fund the Coinbase account, move the funds over to GDAX (all on the same interface), and make your trades.

Also, never enter a market trade, that will kick off the commissions. Instead, enter a stop where you will have to enter in your buy or sell price.
