“Sun also offered a 5% white-hat bounty to the Poloniex hacker.”
Over $100 million left a Poloniex hot wallet, and CertiK calls it a private key compromise. The exchange’s public response was a tweet saying the wallet was down “for maintenance.” Justin Sun promises full reimbursement and offers the thief $5 million to give the rest back. In crypto, a ransom note signed by the victim is called a bounty.
