Buying Ripple XRP with Bitcoin BTC I have Bitcoin in my Coinbase wallet.  I want to buy Ripple on another exchange since Coinbase does not trade Ripple.

Do I copy and paste my Bitcoin alphanumeric key code from Coinbase to the other exchange?
or
Do I hand write the Coinbase Bitcoin alphanumeric key code in the address window in the other exchange that trades Ripple in order to deposit my Coinbase Bitcoin into the other exchange so I can buy Ripple with Bitcoin?
The usual process is this:


You create an account on the exchange.
You go through their menus to deposit bitcoins.
They give you an address to send bitcoins to.
You withdraw from Coinbase to that deposit address.
You wait about an hour.
You now have a bitcoin balance on that exchange that you can trade.
