Yeah, this is more for people who really need it on the spot (like I did that day). I'm going to be making a follow-up tutorial on keeping the money digital and withdrawing it through coinbase soon. I've been hesitant to do so because of how horrible coinbase's customer support is, though. I'm still waiting for them to get back to me on why my bank verification isn't going through even though I am entering the right numbers every time. Very frustrating experience, and because of that I am advising everyone against using it.
