If you're willing to use high leverage to buy the dip, that's fine, but your contract holding time shouldn't exceed one hour. Why? Currently, this is all retail investor behavior. After a sharp drop, retail investors buy the dip, causing a rebound, followed by multiple and prolonged small drops, leading to retail investors selling at a loss. Do you understand now? Gambling isn't impossible, but you need strong judgment and execution. You need to be on the opposite side of other retail investors and make decisions based on their overall behavior.
