In the past few months we have bitcoin ATMs popping up everywhere. Their websites don't seem to disclose the fees, so you have to go to one to find out. All of them around me are doing on-chain only which certainly cramps your style if you need to wait around an hour to exchange for cash. Also, all of them in my area (midwest) require a phone number to send a verification code to. Apparently this satisfies their KYC policies, and allows them to verify you if there is a customer service need. I would like to see lightning bitcoin ATMs to sell bitcoin for cash, it seems like it would be a software-only change.
