Pro trader Koroush identifies $65,800 as the key short-term Bitcoin support; if that level fails, he warns downside momentum could push BTC toward the next major weekly support near $55,000. Recent price action shows weakening momentum with choppy rallies and quick pullbacks, so a break below $65.8K increases probability of a $55K test while a strong bounce above resistance could signal stabilization or a trend shift.

The story reports a named trader flagging $65,800 as the most important short-term level and stating that a break would likely accelerate downside toward ~$55,000; it also cites recent weakening momentum and choppy rallies as evidence favoring continuation rather than reversal.
