What must be seized from a violator's wallet for cryptocurrency transaction control?

Seizing public and private keys from a violator's wallet is critical for controlling cryptocurrency transactions because these keys are essential for accessing and managing digital assets. The public key serves as an address for receiving cryptocurrency, while the private key is necessary to sign transactions and prove ownership. Without the private key, the violator cannot move or access their cryptocurrency, effectively freezing any potential illicit activity related to those assets.

Understanding the importance of these keys is crucial in the context of cryptocurrency, as they are the means by which transactions are authorized. The ability to access these keys allows enforcement agencies to track and potentially recover illicitly obtained digital assets, adding a significant tool in combating financial crime.

Other options, such as bank statements, withdrawal slips, and personal identification, while relevant in some investigations, do not directly pertain to the control and management of cryptocurrency transactions. These items may provide useful information about an individual's financial activities or identity but do not have the same immediate impact on controlling cryptocurrency flow.
