NO NO NO.
You are getting it all wrong. Do NOT buy from coinbase, PLEASE. They are turning into a dictatorship.
If you buy coins at a low price, and the price jumps up, coinbase will rape your money with an excuse of "high risk transaction". If you don't believe me, look at the dozens of other members' complaints.
I'd suggest localbitcoins, and this forum.
I've seen complaints, but I've never had any trouble. Not even when I bought during the $60 dip a few months ago. And it sure beats the heck out of going somewhere to meet strangers.
