How in the world the hwcker is able to withdraw the tokens out of the kucoin exchange and how he is able to sell while staying anonymous and un-tracked, their is high chance that some kucoin employee and insider is involved who made a complete strategy at every step to avoid being caught.
Im not sure if the hacker will able to cash out his funds but the hacker is able to sell his tokens through the use of the decentralized exchange site. But to withdraw a lot of money and that needs very strict KYC verification which will never be done by the hacker.
Im sure if the funds will only sit at his wallet and no more.
When the hacker was sending it to the exchange site and the tokens will be blocked automatically. Kucoin is also still in contact with so many coins to re-issued its token .
To withdraw big amounts of money is not an easy task.
