Imagine walking into your office every day, handling millions in digital assets, and quietly slipping a fortune into your own pocket. That’s exactly what happened in Singapore, where a daring employee turned a routine payroll job into a multi-million-dollar crypto heist. This isn’t a Hollywood script—it’s a real story that unfolded in 2022, culminating in a courtroom drama on February 20, 2025.
A Quiet Crime in the Crypto World
The cryptocurrency ecosystem thrives on trust, technology, and transparency. Yet, every so often, someone exploits that trust for personal gain. In this case, a payroll clerk at a Singapore-based fintech firm orchestrated a scheme so subtle it went unnoticed for months, siphoning off millions in digital coins.
The Mastermind Behind the Theft
Meet Ho Kai Xin, a 31-year-old employee at Wechain Fintech Singapore, a company tied to the popular crypto exchange ByBit. Her job? Managing payroll for nearly 900 workers. What seemed like a mundane role became the perfect cover for a sophisticated fraud that netted her 5.7 million dollars in cryptocurrency.
Ho didn’t hack servers or crack codes. Instead, she used her insider access to manipulate payroll files, adding fake entries that funneled funds to her personal wallets. It was a low-tech approach in a high-tech world, proving that sometimes the simplest methods are the most effective.
The greatest threat to security often comes from within, not from shadowy hackers in distant lands.

How She Pulled It Off
Between May and August 2022, Ho executed her plan with chilling precision. She tampered with Excel spreadsheets—tools as commonplace as pen and paper in most offices. By inserting fraudulent lines, she redirected payments in USDT, a stablecoin pegged to the U.S. dollar, straight to her own digital wallets.
What’s striking is how she masked her tracks. The amounts weren’t outrageous enough to raise instant red flags, and her role gave her the authority to make changes without immediate scrutiny. For months, she operated under the radar, turning her desk job into a goldmine.
Stablecoin
A type of cryptocurrency designed to maintain a stable value, often pegged to assets like the U.S. dollar. USDT, or Tether, is one of the most widely used examples.
Living Large on Stolen Crypto
With millions in her control, Ho didn’t stash it away quietly. She converted the stolen USDT into fiat currency—traditional money—and indulged in a lavish lifestyle. Luxury goods, high-end experiences, and a taste of the good life became her new normal, all funded by her illicit gains.
This wasn’t just a crime of greed; it was a bold statement. Ho lived as if the money was hers to spend, betting that no one would notice the missing millions. For a while, her wager paid off—but only for a while.
The Law Catches Up
By February 2023, the house of cards began to crumble. A sharp-eyed representative from Wechain flagged irregularities, sparking an investigation. Two months later, Ho found herself in handcuffs, facing a reckoning for her actions.
At first, she spun a web of lies, blaming a fictional cousin for the transactions. But the evidence—digital trails, wallet addresses, and recovered assets—painted a damning picture. In the end, she had no choice but to confess.
| Aspect | Details |
|---|---|
| Amount Stolen | $5.7 Million |
| Timeframe | May-August 2022 |
| Prison Sentence | 9 Years, 11 Months |
| Recovered Funds | $1.4 Million |
Justice Served: Nearly a Decade Behind Bars
On February 20, 2025, a Singapore court handed down its verdict. Ho Kai Xin, after pleading guilty to charges of fraud and money laundering, was sentenced to nine years and 11 months in prison. It was a stern message: no one escapes the long arm of the law—not even in the wild west of crypto.
Authorities seized over $330,000 in luxury items and recovered $1.1 million in USDT from her wallets. Yet, a hefty chunk of the stolen fortune—millions of dollars—remains unaccounted for, lost in the labyrinth of blockchain transactions.
Insider theft is rare in crypto firms, but this case highlights the need for tighter internal controls.
Lessons from the Heist
This isn’t your typical crypto hack with masked coders breaching firewalls. It’s a reminder that human error—or human greed—can be just as dangerous as sophisticated cyberattacks. Companies handling digital assets must rethink how they safeguard their operations.
- Insider Threats Are Real: Employees with access can bypass external defenses.
- Simple Tools, Big Damage: Excel tampering proved more effective than hacking.
- Blockchain Isn’t Foolproof: Funds can still vanish if oversight fails.
For crypto users, it’s a wake-up call too. The tech may be cutting-edge, but the risks are as old as crime itself. Trusting a platform means trusting its people—and that’s a gamble not everyone wins.
The Bigger Picture: Crypto’s Growing Pains
Singapore has long positioned itself as a crypto-friendly hub, balancing innovation with regulation. Cases like this test that reputation, raising questions about how well the industry polices itself. Is this an isolated incident, or a sign of deeper vulnerabilities?
The numbers tell a story of their own. With billions flowing through exchanges yearly, even a small breach can have massive fallout. Ho’s theft, while significant, is a drop in the bucket compared to larger hacks—but its simplicity makes it all the more unsettling.
Key Takeaways
- A payroll clerk stole $5.7M in crypto over three months.
- She used basic spreadsheet tricks, not advanced hacking.
- Justice prevailed with a near-decade prison term.
- Millions remain missing, exposing oversight gaps.
What’s Next for Crypto Security?
This saga leaves the crypto world at a crossroads. Exchanges and fintech firms will likely double down on audits, employee vetting, and real-time monitoring. But can they ever fully eliminate the human factor?
For now, Ho Kai Xin’s story is a cautionary tale—a blend of ambition, betrayal, and retribution. It’s a stark reminder that in the race to digitize finance, the oldest tricks can still outsmart the newest tech.
Caught in the act, her tale ends behind bars—but the missing millions linger as a mystery for the ages.
