I'm not sure if this is a strategy or a trader's mistake. What is certain is that the price returned to the initial price because the order at $ 1 has been filled and there are no more orders at the same price, which makes people who sell directly at the market price can be fooled.
you may often see this kind of thing in new token trading, which is more common in memecoins. surely something like that is intentional by certain parties to get attention. from their token holders.
