The short, narrated by The Art of Crypto, recounts the 2018 BitGrail exchange hack in which approximately $195 million worth of Nano tokens were stolen. It explains that exchange founder Francesco Ferrano initially blamed a flaw in Nano’s code, but later investigations exposed severe security shortcomings at BitGrail and revealed that Ferrano had known about the vulnerability for months. The Nano community mobilized to investigate, tracing portions of the stolen funds to other exchanges such as Binance and KuCoin, though most of the assets remain unrecovered and victims are still uncompensated. The video concludes with the cautionary reminder “not your keys, not your coins” and a call to follow for more crypto content.
