go to gdax, click the deposit button under your balance. then click btc (or eth/ltc) address, copy that address. then go to Binance, under the "funds" tab, click deposits and withdrawals, click on the btc (or eth or ltc) that you would like to withdraw, and paste the wallet address from gdax and it will send the coin over. I suggest LTC (20 minute transfer yesterday and less fees.
