📅 August 2 | China – Global Blockchain Forensics
A bombshell is shaking the crypto world five years later: Arkham Intelligence has just revealed that one of the largest Bitcoin thefts in history occurred in 2020… and went completely unnoticed.
This is the mysterious drain of funds from the Chinese mining pool BTC.top, which today, thanks to the rising price of BTC, amounts to a staggering $14.5 billion.
🕵️♂️ The perfect crime… until the chain spoke up
The analysis published by Arkham Intelligence, the on-chain analytics firm, traces a series of covert transactions that occurred during 2020, just as BTC.top was one of the largest mining pools in the world, controlling an estimated 10% of the global hash rate.
According to Arkham, an “unknown entity” transferred more than 100,000 BTC that were in BTC.top’s operational custody at the time.
At the time, no one publicly detected the theft, as the transfers were divided into thousands of small transactions to difficult-to-trace addresses without direct interaction with known exchanges.
The chilling:
2020 value: ~$900 million. Current value (July 2025): $14.5 billion. No confirmed suspects.The chain trail points to wallets that are still active and moving funds in small batches. BTC.top never publicly reported any significant losses. Chinese authorities have not commented so far.
Arkham suggests the operation could be related to insiders from the pool itself or hackers with deep access to the mining consortium's custody infrastructure and digital signatures.
Topic opinion:
This case is simply terrifying. Not only because of the magnitude of the theft, but also because of the absolute lack of visibility and community reaction at the time.
That a loot of this magnitude was siphoned off without generating headlines or public investigations speaks to a period in the ecosystem where transparency was an illusion.
Five years later, blockchain exposes what silence sought to bury.
This incident should serve as an urgent call to strengthen surveillance of custodians, mining pools, and key players in the crypto infrastructure.
Decentralized environments aren't always immune to ghosts.
💬 Should BTC.top be investigated retroactively?
