Great tutorial Jerry. I wish you didn't have to transfer your funds to GDAX, I wish it was directly integrated into Coinbase but oh well, still saving money on buy/sell is awesome. Just as a reminder to all: DON NOT STORE YOUR COINS ON EXCHANGES! They get hacked all the time. Keep your cryptos safe in a cold storage place (paper wallets) / on a cold storage device (Trezor etc). Cheers.
