After I posted about the GEC coin yesterday, a fan reminded me, so I checked the contract of this coin and found a vulnerability. It allows free transfers, meaning it can transfer all coins to one address in a short time and quickly crash the market. Additionally, it has a whitelist feature (allowing its own buying and selling without fees). Overall, the main force is quite aggressive, taking it down in just a minute, giving no one a chance, and specifically choosing to sell in the early morning when others are tired.
