The Ethereum daily KDJ has a risk of breaking downwards. Everyone should pay attention to their positions and set good take-profit and stop-loss levels. If it cannot effectively break through and rise, there is still a risk of a pullback. Some square bloggers say there are no support or resistance levels, or that support and resistance levels are invalid. I can only smile. 😊 Most of the time, they are only invalid when institutions dump heavily. Although yesterday's low of 3669 was not held, the level above 3550 was maintained, compared to those who just buy the dip without levels or direction. Isn't that a need for more precise entries?
