What makes you say that theres dump coming?
Because that is what naturally happens after the hype pump of price by reaching its ATH there will be no direction for the price to go stable ,the next will a dump stage where the panic selling starts and the ones who bought at hype price will lose or if they hold their coin they will be a bag holder .
