2. Enable two-factor authentication (2FA): Set up 2FA for your
Bitcoin exchange accounts and any other platforms that
involve your Bitcoin ID. This adds an extra layer of security by
requiring a second form of verification, usually through a
mobile app or SMS code, to access your account.
when using a mobile device with a sms 2FA, the exchange then has your phone number. which if requested by authorities they can then ping that number and see all of the locations it was spotted on the cellular network.
if you are seen each night to ping at a certain address they can learn that you live(sleep) there and so found out where you live
2FA and use of exchanges is the easiest way to get found especially if you use a mobile device
