Finance Magnates and Crypto.news both report that British software engineer Lewis Barber is suing BitMEX's operator, HDR Global Trading Limited, for £20.4 million over 1,053 unauthorised trades made between 2018 and 2022. They agree that Barber is seeking the return of 324.8 Bitcoin, equivalent to his losses on those trades. However, Finance Magnates provides more detailed information about the legal basis of the claim, citing Section 26 of the Financial Services and Markets Act 2000, while Crypto.news focuses on the lack of FCA authorisation.
A British software engineer, Lewis Barber, has filed a lawsuit against BitMEX's operator, HDR Global Trading Limited, seeking £20.4 million in damages. The claim, reviewed by Guardian, states that Barber lost 324.8 
Bitcoin on 1,053 trades made through five accounts between 2018 and 2022.
Barber argues that BitMEX entered into the disputed perpetual swaps without the authorisation required in the UK. He relies on Section 26 of the Financial Services and Markets Act 2000, which allows customers to seek the return of money or other assets from unauthorised financial services providers.
The case has been corroborated by multiple outlets, including Finance Magnates and Crypto.news. While both agree on the core details of the lawsuit, Finance Magnates provides more specific information about the legal arguments, while Crypto.news emphasises the lack of FCA authorisation for BitMEX's derivatives offerings.
The lawsuit comes at a time when cryptocurrency regulation is becoming increasingly stringent in the UK. The Financial Conduct Authority has been cracking down on unauthorised crypto businesses, and this case could set a precedent for how exchanges operate in the country.
As of October 1, 2023, Bitcoin is trading at $81,257, down 2.55% in the last 24 hours and 2.07% over the past week. The total cryptocurrency market cap stands at $2.79 trillion, with a Fear & Greed Index of 53, indicating a neutral market sentiment.

The chart plots BTC's price: grey is the move before this brief published, the vertical dashed line marks the moment it published, the horizontal dashed line is the price then, and the coloured area is the move since — from Criptano's market data (daily resolution). It shows what happened after the news, not that the news caused it; many factors move prices. Not financial advice.
At today's peer-to-peer rate, 1 BTC ≈ R$409,743.3 (about $81,041.00), down 2.8% over 24 hours. The real itself trades about 0.4% above the official rate on the P2P market, so a Brazilian buyer's effective cost differs from the headline dollar price.
