Monthly size of crypto theft 2020-2022
The value of crypto lost to security threats grew over nine times between 2020 and 2021, with one incident in August 2021 accounting for 610 million U.S. dollars stolen. During this particular incident - claimed to be one of the biggest cryptocurrency heists of all time - an individual person targeted the Ethereum-based DeFi application Poly Network after exploited a flaw in the Network's code. After Poly Network pleaded with the hacker, the anonymous hacker handed back about half of the money - 342 million U.S. dollars - claiming he did the hack "for fun".
