$BTC just ripped $4,000 off the lows and reclaimed $66k.

$875M in liquidations over 12 hours. Classic leverage flush — shorts got squeezed, longs who bought the dip are back in profit.

This kind of violent snap-back usually happens when:
1. Overleveraged positions pile up on one side
2. A catalyst (macro news, whale bid, short-term support) triggers the unwind
3. Forced liquidations create a feedback loop

What matters now: does $66k hold as support, or is this just a relief bounce before another leg down? Watch funding rates and open interest — if they reset and stay neutral, the move has room. If they spike again immediately, we're back to fragile territory.
