✍️ Sample CCI Questions & Answers
1. What is the investigative significance of IP log records obtained from a cryptocurrency exchange?
IP log records reveal the geographic origin of account logins, allowing investigators to determine where account users are actually located and potentially identify them.
2. What is a multi-signature (multisig) wallet and how does it complicate cryptocurrency seizure?
A multisig wallet requires M-of-N private keys to authorize any transaction, meaning investigators must obtain all required keys — often held by different individuals — to move the funds.
3. Which type of transaction complicates tracing efforts?
Mixer or tumbler services are designed to obscure the origin and destination of cryptocurrency funds by pooling and mixing transactions from multiple users. This process deliberately breaks the direct link between sender and receiver, making it significantly more difficult for investigators to trace the flow of funds and identify the parties involved. They are often used to enhance privacy or for illicit purposes.
4. When law enforcement seizes cryptocurrency held on a centralized exchange, what is the typical process?
Law enforcement typically serves the exchange with a seizure warrant, and the exchange then transfers the specified funds to a government-controlled cryptocurrency wallet.
5. What is a blockchain bridge and why is it significant for cryptocurrency investigations?
Blockchain bridges enable asset transfers between different blockchain networks, creating investigative challenges because funds effectively disappear on one chain and reappear on another with a different transaction history.
6. Under the Bank Secrecy Act (BSA), what cash transaction amount triggers a mandatory Currency Transaction Report (CTR)?
The BSA requires financial institutions to file a Currency Transaction Report (CTR) for any cash transaction exceeding $10,000 in a single business day.
