Short-term:

eth: Yesterday it surged to 2490 and encountered resistance, then went sideways. 2500 is the short-term pressure level. Here I judge it to be a continuation of the uptrend. After breaking 2500, it will directly target 2880 (if it stabilizes here, it will break through 3k and target 4k, which is a long-term trend).
The current 2-hour level shows a death cross, corresponding to a pullback to 2268-2255. The upward momentum at the 3-4 hour level is weakening, with support around 2125 and 2074. A short-term pullback to 2125-2066 is a suitable entry point for long positions. Only a drop below 2066 will escalate the adjustment to 1988-1936. The upward trend is still intact; during the pullback, short positions should be exited gradually, while long positions should be entered gradually.
Low points: 2255 (light), 2222 (light), 2126/2112 (normal long, defend 2070), 2074 (normal long, defend 2012) nearby. Breakout stabilizes above 2500, effective levels.
Subsequent high points: 2596 (short-term short, take profit 2512-2488), 2660/2688 (strong resistance, pullback take profit 2596-2566), 2880 (strong resistance, pullback take profit 2750-2722).
