With the price of Bitcoin dropping to $BTC around $85,000, heavy selling by major investors indicates profit-taking and risk avoidance, increasing short-term market volatility. The key price area to watch is the support zone between $80,000 and $82,000, where we previously saw strong buying interest. Maintaining this area ensures the continuation of the upward trend. A break below this level could open the way to reach $75,000-$78,000, while a rebound and recovery above the $88,000-$90,000 level indicates renewed strength and the possibility of continued upward movement.
