Arkham Intelligence has revealed that 127,426 BTC, valued at $3.5 billion, was stolen from the LuBian mining pool in December 2020, marking it as one of the largest crypto heists in history.

The current value of the stolen Bitcoin has risen to approximately $14.5 billion due to price appreciation since the theft.

A Bitcoin developer has proposed a hard fork to transition BTC from legacy wallets to those secured by post-quantum cryptography, aiming to protect against potential quantum computing threats to current ECDSA signatures. The proposal includes a migration deadline for users to move their funds to more secure wallets, and it has sparked debate within the community about its feasibility and implications.
