British Software Engineer Sues BitMEX Operator for Return of 324.8 BTC Over Unlicensed UK Derivatives Trading
Lewis Barber filed a London High Court claim against HDR Global Trading seeking 324.8 BTC lost on 1,053 perpetual swap trades, alleging BitMEX operated without FCA authorization.
Why it matters
The case tests whether UK traders can recover losses from unlicensed crypto derivatives platforms under Section 26 of the Financial Services and Markets Act 2000. Lawyers suggest other UK traders may have similar claims potentially totaling hundreds of millions of pounds.

What happened
British software engineer Lewis Barber has sued HDR Global Trading Limited, the Seychelles-based operator of BitMEX, in London's High Court for the return of 324.8 BTC. Barber alleges the exchange offered perpetual swap derivatives to UK customers between 2018 and 2022 without authorization from the Financial Conduct Authority, rendering the trades unenforceable under the Financial Services and Markets Act 2000. The claim challenges 1,053 losing trades out of approximately 2,294 total trades placed across five accounts. BitMEX has stated the claim has not been formally served on its operating company. The Bitcoin was valued at £20.4 million as of October 1. US authorities previously fined BitMEX $100 million in January 2025 following a Bank Secrecy Act conviction.
