Really? I'm kind of amazed by this whole thing - I never thought there would be a desire to purchase bitcoins in real life with physical cash. I always thought of it more as a online thing people would do via exchanges, smart phone apps, etc.
If you don't mind me asking - Where was the machine? Why were you buying bitcoins there vs just using an online exchange?
I guess it adds another layer on anonymity to it. Online exchanges often require your name and address, and even if they don't, you're probably going to be funding it via a debit card or bank account which can be traced back to you. By using cash, there's no way of identifying who purchased the bitcoins (except via cctv I guess)
