CCI - Certified Cryptocurrency Investigator Illicit Cryptocurrency Schemes Questions and Answers — Questions and Answers
Question 1: An investigator is analyzing a new cryptocurrency project that promised revolutionary returns. The developers, who remained anonymous, aggressively promoted the token on social media, causing a massive price surge. They then suddenly drained the project's liquidity pool and disappeared, leaving investors with worthless tokens. Which illicit scheme does this scenario describe?
- A Ponzi scheme
- A pump-and-dump scheme
- A rug pull (Correct answer)
- A 51% attack
Correct answer: A rug pull
This scenario is a classic example of a rug pull, where developers abandon a project and run away with investors' funds. A key characteristic is the removal of liquidity by the project creators, making it impossible for investors to sell their tokens. While it has similarities to a pump-and-dump, the defining action in a rug pull is the developer's exit and liquidity drain, which is specific to the DeFi space.
Question 2: Which of the following is the primary purpose of a cryptocurrency mixer or tumbler in the context of illicit activities?
- To provide users with better exchange rates
- To stake cryptocurrency for passive income
- To obscure the transaction trail and launder illicit funds (Correct answer)
- To facilitate faster cross-border payments
Correct answer: To obscure the transaction trail and launder illicit funds
Cryptocurrency mixers, also known as tumblers, are services that commingle cryptocurrencies from multiple users to break the link between the sender and receiver, thereby obscuring the transaction trail. This makes them a popular tool for money laundering and hiding the origin of funds obtained from criminal activities.
Question 3: A criminal organization receives a large sum of Bitcoin from illicit operations. To launder the funds, they use a cross-chain bridge to convert the Bitcoin to Monero, then swap the Monero for Tether on a different blockchain's DeFi protocol, and finally cash out through a centralized exchange. What is this money laundering technique called?
- Stacking
- Chain hopping (Correct answer)
- Forking
- Shilling
Correct answer: Chain hopping
Chain hopping is a money laundering technique that involves moving funds across different blockchains to obfuscate their origin. By using cross-chain bridges and decentralized exchanges to swap assets between chains (e.g., Bitcoin to Ethereum to Tron), criminals make it significantly more difficult for investigators to trace the flow of illicit funds.
Question 4: Which characteristic most accurately distinguishes a cryptocurrency pyramid scheme from a Ponzi scheme?
- A Ponzi scheme guarantees high returns, while a pyramid scheme does not.
- A pyramid scheme's returns are generated from a legitimate underlying business.
- A Ponzi scheme requires participants to recruit new members to earn returns.
- A pyramid scheme's structure requires participants to recruit new members to generate returns. (Correct answer)
Correct answer: A pyramid scheme's structure requires participants to recruit new members to generate returns.
The defining feature of a pyramid scheme is its reliance on a hierarchical structure where participants earn money primarily by recruiting new members, who in turn must recruit others. In contrast, a Ponzi scheme is typically a centralized investment fraud where returns for earlier investors are paid using capital from newer investors, without the explicit requirement for investors to recruit others.
Question 5: An investigator is examining a case where a criminal group is using a specific type of cryptocurrency that utilizes ring signatures, stealth addresses, and RingCT to make transactions virtually untraceable by default. Which of the following cryptocurrencies is most likely being used?
- Bitcoin (BTC)
- Ethereum (ETH)
- Monero (XMR) (Correct answer)
- Tether (USDT)
Correct answer: Monero (XMR)
Monero (XMR) is a well-known privacy coin that implements several advanced cryptographic techniques to ensure anonymity. These include ring signatures to obscure the sender, stealth addresses to hide the receiver, and Ring Confidential Transactions (RingCT) to conceal the transaction amount, making every transaction private by default.
Question 6: A group of traders coordinates on a social media platform to buy a low-volume altcoin simultaneously. They create a massive amount of hype with misleading information to attract outside investors, driving the price up significantly. The original group then sells all their holdings at the peak, causing the price to crash and leaving new investors with major losses. This scheme is best described as:
- A Sybil attack
- A rug pull
- Phishing
- A pump-and-dump (Correct answer)
Correct answer: A pump-and-dump
This scenario describes a pump-and-dump scheme. The key elements are the coordinated effort to artificially inflate ('pump') the price of an asset through hype and misleading statements, followed by the coordinated selling ('dump') of the asset by the insiders at the inflated price. This leaves later investors with a devalued asset.
