i tried coinbase and it is more hassle than it's worth. i opened a blockchain wallet, which was easy, but you have to wait to add btc up at first. they put limits on it and you need to upgrade to gold level to be able to put in enough at a time. problem is they hold your bitcoin for up to 14 days for "safety reason" so i still can't send it yet and that sucks big time, because the market dropped and i've lost over seventy dollars just waiting. so wait some more and hope. glad i got enough gear for now.
