According to @AltcoinDaily, Ethereum (ETH) could accelerate higher once it decisively clears the $4,000 level, as shared on X on Dec 11, 2025 (source: @AltcoinDaily on X). Round-number levels like $4,000 are widely watched psychological resistance, and breakout traders typically seek confirmation via a close above the level and rising volume before entering (source: Investopedia on psychological price levels and breakout trading). Derivatives traders also monitor signals around key strikes—such as options open interest clustering and shifts in funding rates—to gauge breakout sustainability (source: CME Group options education and Investopedia on options open interest). Because failed breakouts are common, risk management often includes invalidation on a swift move back below $4,000 or waiting for a retest to hold as support before positioning (source: Investopedia on bull traps and support-resistance retests).
