On March 19, 2021, the Supreme People's Procuratorate and the People's Bank of China jointly issued a typical case on punishing virtual currency money laundering crimes. The case shows that Chen Moumou of Hangzhou knew that the upstream funds came from financial fraud and crimes, but still transferred the fund-raising fraud funds overseas by means of bank transfers and exchanging bitcoins. His behavior constituted money laundering and was sentenced to two years in prison. A fine of 200,000 yuan was imposed.
According to the China Judgment Documents Network, Chen Haibo, without the permission of the relevant state departments, publicized through the Internet, promised fixed income or fabricated high expected income, and attracted unspecified social public to invest in "Malacca Bitcoin Fund" and "player network". ", and suspected of illegally obtaining investment funds through fictitious transactions, tampering with data, and restricting cash withdrawals.
From late October 2018 to early November of the same year, the defendant Chen Moumou knew that his ex-husband Chen Haibo was investigated by the public security organs for alleged fund-raising fraud and fled to Hong Kong. Chen Moumou transferred RMB 3 million of stolen money obtained from the suspected crime to Chen Haibo; After selling the vehicle bought by Chen Haibo with the stolen money at a low price of more than 900,000 yuan, all the money was transferred to Bitcoin "miners" in exchange for Bitcoin keys, and the keys were sent to Chen Haibo for his overseas exchange.
According to the observation of CoinHolmes, an anti-fraud situational awareness system under PeckShield, this case shows a new method of buying bitcoin "miner" keys for money laundering.
Bitcoin mining is the process of bookkeeping, which is the process of confirming transactions that occur in the Bitcoin system within a period of time and recording them on the blockchain. People who mine are called "miners". Mining requires a lot of computing power. As a reward, the miners who successfully grab the bookkeeping rights will be rewarded with bitcoins.
Miners will receive two kinds of rewards for mining, one part is block rewards. According to the Bitcoin protocol, every time a new Bitcoin block is generated, the Bitcoin network will generate N Bitcoins as a reward for maintaining the Bitcoin network Paid to the miner who created this block. Among them, the value of N was 50 when Bitcoin was born, and it has been halved about every four years since then, and it is currently 6.25. The Bitcoin network controls the total amount of Bitcoins in this way. The block reward is the first transaction recorded in each block.
The other part is the transaction fee, which is the sum of all transaction fees in the current block.
In mining rewards, the output address of the block reward transaction is the miner’s direct payment address, which is called the miner’s wallet by default. In order to obtain higher computing power and block rewards, multiple miners can form a mining pool to enhance their computing power. Mining pools distribute rewards to miners. When the mining pool distributes rewards, it will first transfer all the mining rewards to the address of the next-level organization wallet according to a certain amount or other rules, and then distribute the rewards through different organization wallets. As shown below: According to CoinHolmes' observation, with the entry into force of the "Anti-Money Laundering Law" and "Card Breaking Action", traditional money laundering channels have been hit hard, and anonymous, transnational, and difficult-to-trace virtual currencies have become an important channel for money laundering. Under the pressure of law enforcement agencies in various countries, virtual currency trading platforms have also upgraded their anti-money laundering risk control strategies to meet the requirements of relevant law enforcement agencies. According to CoinHolmes anti-fraud experts, before, there were many virtual currency trading platforms with looser anti-money laundering risk control systems. I don't know that it is used in gray industries such as running points and money laundering. The purpose of sellers selling virtual currency is to launder funds, but for buyers, they just think it is currency speculation, so the key point of rectification is to strengthen anti-money laundering efforts on virtual currency trading platforms.The strengthening of supervision has forced money launderers to turn to virtual currency OTC over-the-counter transactions. Under normal circumstances, the seller provides a virtual currency receiving address. After the transfer is confirmed, the receipt and payment can be counted and checked in person. Compared with on-site transactions, OTC merchants generally do not ask buyers' source of funds, identity information, and there is no upper limit on the amount.But such peer-to-peer transactions between strangers also pose potential risks, CoinHolmes found Recently, there have been many virtual currency over-the-counter robberies in Hong Kong , There have been cases of money laundering platforms running away with money in the Mainland.
