So first off, I was asked a phone number for a verification code and then, I had to scan my Bitcoin address QR code. I then inserted 100$ of liquid money into the machine and recieved a notification on my phone telling me that the transaction went through successfully.
The ATM machine ask you for your phone number for verification. This means that a clear data of your transaction has been saved on the ATM's server along with your phone number. And this will allow the ATM server controller to easily find out your identity.
I was very surprised because I didn't think that the proccess would be that fast. To be honest, I will definitly buy from Bitcoin ATM's in the future as I clearly see this as the safest and most anonymous way to buy Bitcoin.
Why do you think this transcation is an anonymous way? Where you passed your phone number and your phone number is registered with your Government id card or Pasport?
