If you’ve been around crypto long enough to remember Dogecoin’s first TikTok pump, you probably thought you’d seen every kind of rug-pull imaginable. Try this one on for size: AU$190 million (about US$123 million) siphoned through what looked like an everyday Sydney payment processor. Crazy, right?
Here’s what actually went down
On Tuesday, the Australian Federal Police (AFP) pulled the curtain back on “Operation Wickham” (their codename, not mine). Investigators allege that a pair of 30-something siblings—let’s call them the Nguyens, because that’s literally their surname in the court docs—set up a squeaky-clean payment services company in 2019. Outwardly, it helped mom-and-pop e-commerce stores settle card transactions. Under the hood, though, it was a full-blown crypto laundromat.
Between January 2021 and May 2023, the company’s business account on BTC Markets and three smaller Aussie exchanges moved roughly 2,500 BTC and 38,000 ETH. (Yes, I triple-checked those figures in the leaked affidavit and still had to sit down.) At today’s prices—call it $31k per BTC and $1.7k per ETH—that’s about the AU$190 million the AFP is waving around in press releases.
How did they get away with it for two-and-a-half years? Two pieces of tech magic and one very dull banking loophole:
- Layering via stablecoins. They hopped into USDT on Tron, bounced it through decentralized swaps like SunSwap (cheap gas fees—sigh), then popped back onto exchanges as BTC.
- Mixer-as-a-Service. Tornado Cash may be sanctioned, but copycat pools running on BSC are alive and kicking. Chainalysis traced at least 11 hops through “0xabc…fee1” contracts with mixer-like signatures.
- Low-value payment exemption. Aussie banks don’t flag anything under AU$10k. So the siblings kept deposits just shy of that threshold—8,000 times. That’s not a typo.
Wait, how did nobody notice?
I’m not entirely sure, but my hunch is complacency fatigue. Remember when Westpac’s AML scandal in 2019 forced every Aussie bank to beef up surveillance? Well, four years later, compliance teams are back to rubber-stamping CSV files at 4:45 PM on a Friday. And crypto settlement volumes aren’t eye-popping after the 2022 crash, so a couple million here or there feels… normal.

Plus, the business was paying GST, filing quarterly BAS statements, and renting a fluorescent-lit office in Parramatta. Legit vibes everywhere.
All roads lead to social-media Ponzi land
Here’s the twist I didn’t see coming: the laundered funds allegedly originated from a Telegram-based investment club called “Greenfields Mining.” The admins promised 15% monthly returns by “leveraging Bitcoin hashrate bought wholesale from Kazakhstan.” I literally face-palmed reading that line in the indictment. If 2023 taught us anything (looking at you, Celsius), it’s that any guaranteed yield north of your favorite savings account is probably a funnel of tears.
The AFP claims at least 3,200 victims wired fiat into the Nguyens’ payment processor, believing they were buying hashpower credits. From there, the fiat morphed into USDT, took that Tron merry-go-round, and—poof—gone.
The blockchain breadcrumbs
You can follow the money yourself; the AFP helpfully published two master addresses:
- BSC:
0x04f...c1b7 - BTC:
bc1q0...9lsk
Fire them into OKLink or Blockchair and you’ll see dozens of hops to Binance and KuCoin in 2022, tapering off once Binance tightened KYC last August. After that, funds mostly hit Huobi, which only recently ditched its sketchy “phone-number-only” tier.
Honestly, I’m surprised they didn’t touch Monero. Maybe they thought staying on mainstream chains looked more innocent. There’s a quote from Vitalik that floats around: “Anonymity loves company.” These guys tried to hide inside the crowd rather than go full ninja, and it almost worked.
Why this matters for your portfolio
Okay, you’re not running a scam (I hope). But this saga throws up a few neon warning signs:
- Regulators are dialing up on-chain forensics. If the AFP can untangle 15 hops across three chains, imagine what the IRS or the ATO will manage next year with AI-augmented tracing tools. Privacy coins are bound to come under even harsher fire.
- Centralized exchanges remain chokepoints. Every exit to fiat left a KYC trail. Once the AFP subpoenaed exchange ledgers, the paper trail unfolded like an IKEA manual. That’s bullish for DEX liquidity—but watch for stricter on-ramps.
- Stablecoins are the new getaway car. The Tron-USDT combo (low fees, huge liquidity) has basically replaced Bitcoin mixers. Tether better hope its upcoming audit lands squeaky clean, or regulators will lose it.
Tangential thought: remember when Vitalik dumped $1 billion in SHIB to India’s Covid fund? That single tx taught governments that big, public transfers can be traced and taxed. This case will echo that lesson in Canberra’s parliament next budget season.
What happens next?
The Nguyens face up to 20 years for money laundering under Australia’s Criminal Code Act 1995. But what I’m watching is ASIC’s pending civil suit. If the court declares the payment processor “unregistered financial services,” every bank that touched its flows could face fines. Think CBA, ANZ—those shares might wobble next earnings call.
Another subplot: the AFP froze roughly AU$56 million in crypto across seven exchanges. That stash will likely be auctioned, just like the U.S. Marshals Service did with Silk Road BTC (which Tim Draper famously bagged at a discount). If you’re hunting for bargain ETH, keep your eyes on GraysOnline notices; Aussie law enforcers usually off-load there.
Could better tech have stopped this?
Short answer: maybe. Chainlink’s proof-of-reserves model could let payment processors verify that customer deposits equal on-chain balances. But adoption costs money, and scammers don’t spring for extra audits. Likewise, zero-knowledge KYC (what Polygon ID keeps teasing) might allow you to prove you’re not a sanctions hit list without revealing everything else. We’re not there yet.
I’m also curious whether open-source AML tooling will gain traction. Right now, the cool kids at Rotki are working on a “red flag” plugin that screams if funds pass through sanctioned mixers. Imagine Metamask popping a skull-and-crossbones before you sign. That tiny UX nudge could save thousands of normies.
The part that still bugs me
I keep circling back to the victims. Average deposit size: AU$2,400. That’s not whale money; that’s someone skipping a Bali vacation for a promised 15% yield. The AFP recovered only a quarter of the total haul so far. Unless ETH miraculously 5×’s by the court date (never say never), most folks are taking a painful haircut.
So when someone DMs you a no-risk mining deal, remember this article, laugh politely, and hit block. You’ll sleep better—and keep your travel fund intact.
