Bitcoin (BTC) faced renewed selling pressure during October 1–8 after an early-week rally.

BTC briefly traded above $87,100 before falling toward $81,000 on October 8, as rising US Treasury yields, a stronger dollar, and geopolitical tensions weighed on risk appetite. Looking ahead, $80,000–$81,000 is a potential support zone, while $85,000–$87,000 represents an area of resistance rather than a guaranteed price target.
