Bitcoin's rally has stalled after hitting a high above $87,400 on Sept. 21, with analysts closely watching the $82,000-$83,000 zone. STS Digital's Jeff Anderson said a break below $82,000 could lead to a slip into the high $70,000s, attributing recent weakness to rising U.S. Treasury yields. Bitget Wallet's Lacie Zhang sees the $81,500-$83,000 region as crucial for maintaining a constructive market structure, also monitoring ETF flows and 10-year Treasury yields. Nexo Dispatch's Iliya Kalchev suggests a sustained break below $80,000 would indicate the market is not ready to push higher for some time.
