Glad to hear things have worked out...I started on coinbase as well...I believe they have a GDAX exchange you might look into to trade other coins or use an exchange like Bittrex as a starting point...usually set up easy...learn to transfer in some bitcoin to use for trading as that's easier than trying to get accepted to use fiat...if you do set up...always do a small test transfer first...again...the process isn't real "user" friendly...but worth exploring if you want to expand your horizons...definitely what you own are what I consider the "big three"...and look at Litecoin finally making a move! I use the cyrpto compare blog site to learn a lot about other coins and exchanges...good luck.
