Cryptocurrency platform Poly Network was hit with a major attack last week which saw the hacker, or hackers, make off with more than $600 million worth of tokens.
In a bizarre twist, the hacker has now returned most of the stolen money but is withholding more than $200 million of the funds until “everyone is ready.”
Poly Network promised the hacker a $500,000 bounty for the restoration of user funds, and even invited them to become its “chief security advisor.”
Coincheck lost some $534.8 million in digital coins in 2018. Mt Gox was mugged for $450 million. Poly Network now becomes the largest heist.
