One user wrote they lost almost 104 BTC (~$2 million) from an account that they said they only ever connected to FTX a year ago, with an API key they had not saved, and which had since expired and been downgraded to a free account. Another reported losing about $1.5 million.
FTX CEO Sam Bankman-Fried wrote on Twitter that FTX would compensate the affected users for roughly $6 million in total. He wrote in all caps that he did not want this to be considered a precedent, and it was "a one-time thing". He also stressed that FTX was not responsible for the exploit, and that the users had been tricked by phishing sites impersonating other reputable trading services.
