Sometime we cant anticipate such event to occur. Rugging is one of the worst scenario for investors and traders. Yes nothing can absolutely get away with an instant rug. A developer likely to pull it off when everyone get off guard. As the project get hypes then it will definitely go down as soon as they clicked the bomb. Dont be fooled by such hype when the codes embedded shows a potential rug. It just does mean that they are really gonna do it anyway.
