Bitcoin rebounded from $75,000 to nearly $82,000 last week, supported by institutional demand and liquidations of bearish positions, but the advance stalled at a resistance band between $81,500 and $82,300. The cryptocurrency reached roughly $81,700 on September 19 after a 25.8% rise over 90 days and had held above $74,000 for 30 consecutive days, though repeated selling near $82,000 has limited further gains. Geopolitical tensions linked to fighting between Saudi Arabia and Iran-backed Houthi forces in Yemen added uncertainty, while technical analyst Ali Martinez said the TD Sequential indicator shifted from a buy signal near $75,000 to a sell signal after Bitcoin approached $81,500. Market participants remain divided over whether Bitcoin has entered a new bull phase, with analysts watching for a sustained break above $82,000 or $83,000 and others warning of downside risk if support fails.
