Coinbase Director Suggests Hack Behind $8B Bitcoin Movement

One of the Coinbase directors, Conor Grogan, raised alarm over $8 billion worth of inactive Bitcoin. He opines that it is the movement that might signal a hack. The Bitcoin is a seven-year-old one. Grogan wonders it is not a typical sell-off. He has the suspicion of an organized security breach. In its recent report, BeInCrypto purports that a block of 20,000 BTC, or more than 2 billion dollars, was transferred through 2011 wallets. Coinbase is investigating the recent movement of $8 billion in Bitcoin.

There is Crystal Intelligence data that backs the theory of hacking. In 2025, a Bybit hack took away $1.4 billion worth of Ethereum. The hack had been done through phishing, indicating sophistication in malware. Grogan believes that such methods would work in the Bitcoin transfer. The size and inert nature of the funds further compounds his suspicions. Conor Grogan, a Coinbase director, also suspects the Bitcoin transfer may be linked to a hack.

Blockchain Analysis Challenges Hack Theory

According to Arkham, in his blockchain analysis, Grogan is wrong. According to the analysis, the transfer of Bitcoins was not a hack. It might be concluded as a consolidation; some experts agree that it is a wallet problem. Other analysts indicate that it might not be the sole gamble. Cointelegraph featured the opposing opinion about the Bitcoin transfer. But although none of the theories has been proved by a peer-reviewed research, both of the theories remain feasible.

Coinbase’s involvement in the investigation highlights the growing concerns over crypto security. Crypto forensics remain at its early stage. This unavailability of research makes the investigation difficult. At least, the Mystery of Bitcoin transfer remains unresolved at this point. The theory by Grogan is still one of the dominant ones.
