A Singaporean man in his 20s has pleaded guilty in U.S. court to helping steal 4,100 bitcoin worth about $245 million, one of the largest cryptocurrency heists ever prosecuted in the United States, underscoring how quickly cybercrime can translate into massive losses for investors and heightened pressure on crypto security.
Bitcoin Theft Case Raises Crypto Security Concerns
The defendant, Malone Lam, appeared in the U.S. District Court for the District of Columbia on Thursday and admitted his role in a scam that prosecutors say began with online gaming contacts and ended with a takeover of a victim’s Google Cloud account, personal computer and bitcoin wallet keys. The case matters beyond the lurid details because it highlights the continuing vulnerability of self-custodied digital assets and the operational risks that still hang over the broader crypto market.

Authorities said Lam and accomplices posed as employees of Google Cloud and the Gemini crypto exchange to trick a Washington, D.C., victim into believing there were unauthorized access attempts on the account. Once inside, they siphoned off the bitcoin and then spent the proceeds on luxury cars, Miami mansions, watches and nightclub excess, behavior that ultimately helped lead the FBI to arrest them in September 2024.
Lam’s guilty plea adds a high-profile conviction to a case that prosecutors say is among the largest crypto thefts in U.S. history. He now faces up to 30 years in prison after further proceedings, while U.S. Attorney Jeanine Ferris said the government will continue to target criminals who “weaponize technology” to steal from victims.
For investors, the case is another reminder that headline gains in bitcoin and other digital assets come with security and custody risks that can hit exchanges, payment firms and holders alike. That is especially relevant as bitcoin trades around $76,700, with the coin still above its 50-day and 200-day moving averages but showing softer momentum in the latest sessions, while Coinbase and MicroStrategy have also retreated from recent levels.
The broader narrative is the collision between crypto’s global liquidity and its weak points: social engineering, cloud-account compromise and wallet access. The next catalyst is the criminal case itself, along with any renewed scrutiny of custody practices, exchange controls and law-enforcement efforts to trace stolen digital assets across borders.
