ETH/BTC Reclaiming Macro Bottom — Altcoin Momentum Incoming?

ETH/BTC tagged its 2019 cycle low back in April 2025 — a key macro support level that’s held up for nearly six years. Since then, it’s printed a clean rebound followed by a textbook retest. Now it's threatening to break out of the pullback structure formed over the past few months. If this breakout plays out, ETH could lead the charge for altcoins, signaling the early stages of an altcoin rotation.
