What is a crypto automated teller machine (ATM)?
Could you elaborate on the concept of a crypto automated teller machine (ATM)? I'm curious to understand how it differs from traditional ATMs and what functionalities it provides specifically for cryptocurrency transactions. Is it designed to allow users to buy, sell, or withdraw cryptocurrency? Does it require any specific technical knowledge to operate? Additionally, are there any security measures implemented to protect users' funds and transactions? I'd appreciate a concise yet informative explanation of the key points regarding crypto ATMs.
