In November 2021, federal agents found more than 50,000 Bitcoin hidden at James Zhong’s home in Georgia. Zhong had stolen the Bitcoin from Silk Road in 2012 by exploiting a flaw in the marketplace’s withdrawal system. The Justice Department later secured forfeiture orders covering 51,680.32473733 Bitcoin, valued at more than $3.4 billion at the time of seizure.
How Zhong stole Bitcoin from Silk Road
Silk Road was a darknet marketplace for illegal goods and services that operated from about 2011 to 2013. Its founder, Ross Ulbricht, was convicted in 2015. Zhong did not use the marketplace to buy or sell goods. Instead, he used accounts there as a way to exploit its withdrawal process.
The withdrawal exploit
In September 2012, Zhong created about nine Silk Road accounts. He deposited between 200 and 2,000 Bitcoin into them, then triggered more than 140 rapid withdrawals. According to the Justice Department, the system released multiple withdrawals against a single deposit, allowing Zhong to withdraw far more than he had put in.
In one example described by prosecutors, a 500-Bitcoin deposit was followed less than five seconds later by five withdrawals of 500 Bitcoin each, all within the same second. The withdrawals produced a net gain of 2,000 Bitcoin. The scheme was an abuse of Silk Road’s withdrawal processing, not a compromise of Bitcoin’s underlying network.

How investigators traced the money
The Zhong case involved tracing Bitcoin through a decentralized mixer, an overseas exchange and other tools. The Justice Department’s account of the earlier tracing work says investigators followed the stolen proceeds despite those steps to obscure their movement.
A separate Silk Road recovery in 2020
The government’s 2020 recovery was a different case, not the seizure from Zhong’s home. IRS Criminal Investigation (IRS-CI), assisted by a third-party Bitcoin attribution company, identified 54 previously undetected transactions tied to Silk Road and traced funds to a Bitcoin address associated with “Individual X.” The government seized thousands of Bitcoin worth more than $1 billion. Chainalysis and Excygent assisted that investigation.

That earlier case helps explain the broader Silk Road investigations, but it should not be combined with Zhong’s 2021 seizure: the cases involved different tracing leads, defendants and forfeiture proceedings.
What agents found at Zhong’s home
On November 9, 2021, IRS-CI agents searched Zhong’s home in Gainesville, Georgia. They recovered approximately 50,491.06251844 Bitcoin. Some was in an underground floor safe; another portion was stored on a single-board computer submerged under blankets in a popcorn tin.

Agents also seized $661,900 in cash, 25 Casascius physical-Bitcoin coins containing about 174 Bitcoin collectively, and precious-metal items. The coin figure is separate from the Bitcoin recovered electronically.
How the amount reached more than 51,000 Bitcoin
The Bitcoin recovered during the home search was not the only asset later covered by the forfeiture case. Zhong voluntarily surrendered additional Bitcoin between March and June 2022; the Justice Department’s final accounting lists 1,004.14621836 Bitcoin surrendered in total.

Bitcoin Cash fork proceeds
Because Zhong still held the stolen Bitcoin when Bitcoin Cash split from Bitcoin in August 2017, he also received a matching amount of Bitcoin Cash. Prosecutors said he exchanged that Bitcoin Cash through an overseas exchange for about 3,500 additional Bitcoin. By late 2017, they estimated his crime proceeds at about 53,500 Bitcoin.
Seizure and final forfeiture figures
The figures in Justice Department announcements refer to different stages of the case, so they are not interchangeable:

| Case figure | Amount | What it describes |
|---|---|---|
| Home search, November 9, 2021 | Approximately 50,491.06251844 BTC | Bitcoin recovered from Zhong’s Georgia home. |
| 2022 announcement | Approximately 50,676.17851897 BTC; valued at $3.36 billion | The announced seizure quantity and valuation at that stage of the case. |
| Final forfeiture orders, 2023 | 51,680.32473733 BTC; valued at more than $3.4 billion | The Bitcoin covered by the final orders; the dollar figure is its value at the time of seizure. |
The final orders also covered cash, precious metals, the Casascius coins and Zhong’s 80% interest in RE&D Investments, LLC. A forfeiture order transfers legal rights in assets to the government; the order itself does not establish that the Bitcoin was later sold or say what happened to it after forfeiture.

Zhong pleaded guilty to one count of wire fraud on November 4, 2022. On April 14, 2023, Judge Paul G. Gardephe sentenced him to one year and one day in prison. The sentence was for the wire-fraud scheme involving Silk Road withdrawals.
Why the $3.4 billion figure needs a date
Bitcoin’s market price changes, so $3.4 billion is not a current valuation or a fixed amount of cash the government received. It is the Justice Department’s historical estimate of the forfeited Bitcoin’s value at the time of seizure. The final forfeiture announcement used the later accounting total of 51,680.32473733 Bitcoin and described its value as more than $3.4 billion.
