Are Quantum Computers Taking Bitcoin? Analyzing Josh Mandell's Assertions and Expert Reactions

Quantum Computing and Bitcoin Security: Josh Mandell claims that quantum computers are being used to siphon Bitcoin from inactive wallets, suggesting a major actor is extracting funds without market disturbance, which challenges Bitcoin's cryptographic security.

Expert Skepticism: The Bitcoin community and experts have largely dismissed Mandell's claims, citing the current limitations of quantum technology and the lack of evidence for such thefts, emphasizing that any observed wallet activity is likely due to benign reasons.

Technical Barriers to Quantum Attacks: Current quantum computers lack the necessary qubits and error correction capabilities to effectively break Bitcoin's cryptography, with many experts predicting that practical quantum attacks are at least a decade away.

Onchain Data Analysis: No concrete evidence of quantum-based theft has been found on the blockchain, with dormant wallet activity often explained by normal upgrades or reactivations rather than unauthorized access.
