You're all missing a key detail. It's not really about the cash, it's about the Bitcoin. If someone knows you have Bitcoin, and they successfully rob you, they can do so anonymously. No one is ever going to go for your banking app, as what they will do? Incriminate themselves by transferring your balance to their name? Bitcoin, on the other hand, is transferred to a pseudonymous address. That's the difference between the risk of a cash ATM and a Bitcoin ATM.
How can a robber do so anonymously? There's a significant difference between robbery and theft or stealing. In criminal law, robbery is a more serious crime than theft. If somebody follows a person from the Bitcoin ATM and robs him/her of Bitcoin, it has to be done physically and forcibly. It isn't like when somebody steals from a Bitcoin wallet. Theft can be done anonymously and from far away.
Cash is more anonymous than Bitcoin. If a criminal robs somebody coming from a fiat ATM, why would he/she be incriminating himself/herself by transferring the balance to his/her name? The robber takes cash, cold cash.
You are missing the point.
When someone goes to an ATM and gets cash, a thief is limited only to the amount of cash that comes to an ATM, which is usually too insignificant for someone to take such a large risk like committing theft. However, if someone is using a Bitcoin ATM, it's not just the cash that is on the table, it's whatever is also in their Bitcoin stash, making the risk and reward higher for someone who is willing to go that length to commit such a crime.
TLDR:
- A bank ATM transaction is limited to the cash that comes out of the ATM.
- A Bitcoin ATM transaction is open to both the cash being stolen, and the Bitcoin as well.
There are stories of kidnappings and muggings happening from Bitcoin ATM transactions where the focus is more so the Bitcoin than it is the cash. It definitely has happened before.
