PANews July 5 news, Coinbase executive Conor Grogan tweeted that the recently transferred BTC address (valued at approximately $8 billion) may have been hacked or had its private key compromised. Conor Grogan pointed out that one of the related addresses initiated a test transaction about 14 hours ago via the BCH network and transferred all BCH. About 1 hour later, its BTC wallet began transferring assets. The wallet holder may be testing the private key in a low-profile manner, as BCH has not been closely monitored by whale tracking services. This speculation arises because other BCH wallets have not been affected at all. Conor Grogan emphasized that these are extreme speculations, but the movements here are very strange. If the speculation is true, this would be the largest theft in human history to date.
