During the recent rise of Ethereum ETH, the market has always respected 4-hour oversold. Every time I explore near the oversold area, it basically gives me a good opportunity for a rebound. So I will continue to keep an eye on this rhythm, and the next time there is a 4-hour oversold, it will be a location worth paying attention to, not necessarily buying, but focusing on it. Blindly guessing, it will only be oversold for 4 hours after falling to 2300~
