Nice explanation! There is a Bitcoin ATM about a half an hour away from me and I've used it a couple of times. It certainly is very easy to use, as long as the scanner on it is clean and you turn up the brightness of your phone if you are using it to display your wallet address. The fees on the machine near me were minimal, and I recieved my Bitcoin in a very short amount of time. Thanks for writing about this! I've been wondering if it's worth it investing in one and placing it in a high-traffic location...I have a feeling it would be an awesome way to make some money! Keep up the good work!
