Two whale walls just showed up right above spot—$20.48M at $83,425 and $17.14M at $83,500. That's $37M+ in sell orders stacked tight. Classic resistance cluster. If $BTC runs into these and stalls, expect a quick rejection or chop. If it punches through, those walls flip to support and we get momentum continuation. Watch how price reacts on approach—hesitation means fade, clean slice means chase. Whale orders this size don't sit there for decoration, they're either defending a level or baiting a liquidity grab.
