Simple explainer on why ETH moving is often the last straw. ETH is the heaviest major asset and one of the least liked. It's been underperforming for years and has no strong catalysts. It trades more like a slow "dino" coin - and if traders want to rotate into older assets, there are others with stronger narratives (like XRP or LTC ETFs). ETH usually moves late in mini-cycles because it's not the first choice for traders chasing momentum. Early in a move, people want faster, higher-beta assets that can move 30%+ quickly. ETH, being heavier and slower, gets ignored at first. It's only when most faster plays are already extended that traders rotate into "what's left" - and ETH becomes the fallback. When ETH finally starts moving, it's often a sign that the board is picked over. The easy trades are gone. Once the rotation into ETH plays out, there's no fresh energy left, and the market unwinds. Over time this behaviour has become reflexive. Traders recognise that ETH moving usually signals exhaustion, so they start selling faster, which accelerates the reversal.
