Bitcoin user claims he was victim of hack that led to record $3 million in transaction fees

A  Bitcoin user claimed that hackers stole more than 139 BTC from them, which is related to the record-breaking transaction fee of 83.65 BTC ($3.1 million) paid last week. The same user signed a message that seems to indicate they have the keys to conduct transactions, but it could also be signed by the attacker if the wallet was compromised.
