Tuesday daytime Bitcoin and Ethereum strategy

Recently, Bitcoin and Ethereum have shown weak characteristics of "rising sharply and then falling back + narrow-range oscillation." Yesterday, after reaching 90,373, they quickly pulled back and failed to hold above the 90,000 level. Both Bitcoin and Ethereum followed suit with oscillating declines, but neither effectively broke below key support zones. The short-term downward momentum continues to weaken, presenting a pattern of "weak but not collapsing." From the 4-hour chart, Bitcoin has formed multiple tests and rebounds near critical support levels, with a potential double bottom structure emerging, indicating that the bulls are beginning to accumulate strength at low levels.
Short-term support focuses on the 86,000-86,500 range, with core support at around 85,000. On the resistance side, attention is on the 88,000-88,500 range; a breakout could target 90,000.

Ethereum's core support is in the 2800-2820 area, with short-term targets of 2960-3000, and core resistance at 3050-3070.
