Do Bitcoin ATMs need a cell phone number?

As a finance professional specializing in cryptocurrencies, I'm often asked about the various nuances involved in using digital currencies. One such query that frequently arises is: "Do Bitcoin ATMs require a cell phone number for usage?" This question underscores the privacy concerns and security measures that many users have when it comes to accessing and managing their digital assets. While some Bitcoin ATMs may request a cell phone number for verification purposes, it's crucial to note that this is not a universal requirement. Many ATMs offer alternative verification methods such as email or even a personal identification number (PIN). Understanding these options is key for users who value their privacy and security when utilizing Bitcoin ATMs.
