Bitcoin Analysis Weekly — 2026-09-28
Bitcoin slipped below $83,000 on September 28 as geopolitical tensions (stalled Iran talks) and a derivatives sell-off spooked traders, though the asset still sits only ~33% below its all-time high after a strong Q3. Sentiment remains constructive: Bitcoin ETFs just posted a 2026-record weekly inflow of $2.39 billion, and whales have accumulated 113,950 BTC over the past 10 weeks. The key battle zone is $82,500–$87,500 heading into October.
