- LuBian suffers largest Bitcoin heist, uncovering systemic vulnerabilities.
- 127,426 BTC stolen from LuBian remains unmoved.
- Arkham Intelligence reveals heist impact, with $14.5 billion involved.
In December 2020, LuBian, a Chinese Bitcoin mining pool, suffered a major theft of 127,426 BTC due to a key vulnerability, revealed by Arkham Intelligence in August 2025.
This discovery highlights ongoing security flaws in crypto infrastructure, with potential market instability as $14.5 billion worth of stolen BTC remains unmoved.
The massive Bitcoin heist targeting LuBian has surfaced, recorded as the largest crypto theft ever with 127,426 BTC stolen in December 2020. The hack remained undisclosed until Arkham Intelligence’s August 2025 revelation.
Key players involved include LuBian, a major Chinese mining pool, and Arkham Intelligence led by Miguel Morel. LuBian accounted for nearly 6% of Bitcoin’s hashrate before the hack.
The stolen BTC, now worth $14.5 billion, remains unmoved, impacting market stability. Bitcoin’s price stays near $112,726, indicating market resilience despite the theft’s scale.
The incident dwarfs previous heists like Mt. Gox and Bitfinex, setting a precedent for dormant, large-volume stolen BTC with far-reaching financial implications.
LuBian’s attempt to contact the hacker through blockchain messages emphasizes the gravity of the breach. The absence of official statements or regulatory reactions complicates resolution efforts.
Potential consequences include evolving regulatory scrutiny and technological responses to enhance security protocols, informed by Arkham’s detailed insights and historical trends from past incidents.
Miguel Morel, Founder & CEO, Arkham Intelligence, – “Our findings indicate that the hack of LuBian represents the largest Bitcoin heist in history, with serious implications for security and market stability.”
