Can anyone point me in the best direction to convert my Bitcoins to Ripples?  I just recently purchased some Bitcoins in order to convert them to ripples but I'm not sure what to trust.  I'm new to it all and have been reading up on everything but its all still a bit new to me.  I also don't know what my "address" is.  I'm on shape shift trying to convert and it says I need three things:
1. Your Ripple Address(destination address)
2. Your Bitcoin refund address
3. Destination tag

I'm still waiting for my bitcoin transaction to go through but I was hoping to learn more about bitcoin and how to trade/convert it to other currencies such as ripple while I await the transaction process.  I purchased my bitcoin on Coinbase and I'm open to using any of the exchanges that offer ripple.  Any tips?
