Crypto Law Brief: Chinese Law Governs Claims to $5 Billion in Seized Bitcoin, Seoul Blocks 27 Exchanges, and One Key Mints $1.7 Million

Tuesday's crypto news turns on jurisdiction and access: who decides a claim, who may serve customers, and who holds the key that moves tokens. A London judge narrowed the path for Chinese fraud victims seeking a share of $5.1 billion in seized bitcoin, Seoul cut off access to 27 offshore exchanges without going to court, and a token on Base lost $1.7 million because one address could mint supply by itself.

A London Court Decides Which Country's Law Decides Ownership

Mr Justice Mark Turner handed down judgment in the UK High Court on Monday, October 12, holding that Chinese law, not English law, governs whether investors in Zhimin Qian's Ponzi schemes have any claim to the 61,245 bitcoin seized by London's Metropolitan Police. Qian ran the schemes in China from 2014 to 2017 and was sentenced last November to 11 years and 8 months for money laundering. The coins are worth roughly $5.1 billion today.

The ruling decides no one's ownership. It decides which law answers that question, and in a case this size the choice is most of the outcome. Applicants under Section 281 of the Proceeds of Crime Act 2002 must establish a proprietary interest in the specific property; a personal claim to be repaid as a creditor does not reach the coins. Caixin reports victims may be limited to their original investments plus interest rather than a share of bitcoin's appreciation since 2017. Fieldfisher, lead firm for the individual claimants, says it is pursuing an appeal.

Seoul Blocks 27 Exchanges Without Going to Court

South Korea's Financial Intelligence Unit said Tuesday it is blocking domestic web access to 27 unregistered offshore exchanges, including KuCoin, BitMart and MEXC, after the Korea Communications Standards Commission approved the restrictions in reviews on October 6 and 7. Apple and Google pulled these platforms' apps in 2025; the website blocks close the remaining door. The FIU has referred 44 operators to investigators.

No court ruling and no evidence of customer harm is required here: regulators can act as soon as they detect unregistered activity, and only 28 virtual asset service providers hold FIU registration. For a customer with a balance on a blocked platform, the question is not whether the block is lawful but whether withdrawals still work. The FIU warned that customers of unauthorized platforms may have difficulty recovering funds.

One Relayer Key, 19 Million Tokens, $1.7 Million Gone

Autheo's THEO token fell more than 90% after an attacker minted 19 million tokens out of nothing on Base and sold them into liquidity pools, taking roughly 700 ETH plus about $700,000 in WETH, USDC and cbBTC across some 54 swaps. MEXC halted THEO deposits and withdrawals Tuesday.

The failure was configuration, not cryptography. The contract relied on a Hyperlane Trusted Relayer ISM, which lets a single address execute cross-chain messages with no validator signatures and no second check. No postmortem has been published, and it is unconfirmed whether that key was stolen, misconfigured, or used by someone authorized to hold it. A compromised key, a negligent deployment and an insider point toward different defendants and different theories of liability.

Money Leaves the ETFs Ahead of Wednesday's Inflation Print

Spot bitcoin and ether ETFs shed about $150.8 million on Monday, per Farside Investors data, with BlackRock's IBIT accounting for the entire $65.4 million bitcoin outflow. Bitcoin swung between roughly $81,400 and $84,000 as about $771 million in leveraged positions were liquidated, $685.6 million of them longs, with September CPI due Wednesday morning.

What This Means for You

If you hold assets on an offshore exchange that is not registered where you live, the Korean action is the template rather than the exception: access can vanish before any allegation against you, and the withdrawal window may be short. Check whether your venue is registered where you are, and if you hold a bridged token, find out who controls its mint function.

The London ruling is a reminder that choice of law often decides recovery cases before anyone argues the merits. Victims pursuing seized assets should build a record supporting a proprietary claim to identifiable property rather than a debt. Projects should treat bridge key management as compliance exposure rather than devops housekeeping, because regulators and plaintiffs alike will ask what controls existed and who was told about them.
