South Korea’s FIU warns Bithumb of serious trouble, signaling that South Korea is tightening the screws on crypto compliance. The company, as we speak, is looking at a possible six-month partial suspension.
The crypto space loves to celebrate skyrocketing adoption, but let’s be real: scams, hacks, and shady dealings have exploded right alongside it. On March 9, 2026, South Korea’s Financial Intelligence Unit (FIU) sent a preliminary notice to Bithumb, the country’s second-biggest crypto exchange, warning of a potential six-month partial business suspension and possible sanctions against the CEO himself.
Why would Bithumb get a six-month ban?
Sure, the six-month timeline grabs headlines, but the real red flag is why it’s happening. Regulators say Bithumb didn’t follow Anti-Money Laundering (AML) rules under the Special Financial Information Act. Specifically, unregistered overseas platforms and lax enforcement of Know Your Customer (KYC) procedures, as per FIU. By letting transactions flow through unverified foreign entities, Bithumb may have opened a backdoor around Korea’s strict capital controls.
A sanctions review committee is set to decide the final call later this month, likely around March 16, but the ripple effects are already hitting hard. This comes right after Bithumb’s infamous “ghost coin” blunder in February, where a massive clerical error temporarily credited users with roughly $40 billion in Bitcoin.

That fiasco alone has authorities eyeing other big players like Coinone and GOPAX, hinting at a wider crackdown on the horizon.
Bithumb isn’t going down without a fight
A company spokesperson pushed back, stressing that “this is only a preliminary notice, not a final sanction, and adjustments could still happen during the review process.” They also clarified that any restrictions would mainly hit new members’ virtual asset withdrawals, leaving existing users free to trade as usual.
This isn’t Bithumb’s first brush with regulators. Back in November 2025, Upbit’s operator, Dunamu, got slapped with a 35.2 billion won fine and a three-month partial suspension over millions of KYC violations. Korbit faced its own 2.73 billion won penalty earlier this year. Now Bithumb could face double the suspension time Upbit did, showing just how seriously authorities are taking these issues.
These “partial” suspensions rarely mean full shutdowns. They typically block new users from transferring crypto out while letting longtime customers keep trading, depositing, and withdrawing normally.
On-chain data tells an even clearer story. CryptoQuant numbers show Bitcoin flows between exchanges involving Bithumb have tanked dramatically. In the volatile stretches of late 2025 and early 2026, when Bitcoin hovered near $70,000, massive transfers were common, often signaling big institutional moves.
However, they have shrunk to a measly 15.9 BTC. Traders are clearly hitting pause, waiting to see what the Sanctions Review Committee decides.
