$BTC broke under $66k, $ETH slipped below $1,850 — straight down, no relief bounce. That's the kind of action that shakes out weak hands and tests conviction. When price falls through air pockets like this, it means liquidity dried up and there's no one stepping in yet. Classic capitulation feel. The question isn't why it dumps — it's where support finally shows up. Watch for volume spikes and divergence on lower timeframes. If you're long, your stop should've been clear before this. If you're waiting to enter, let it prove a floor first. Don't chase a falling knife just because it's falling fast.
