Bitcoin and the broader crypto market turned more volatile on Sept. 9, with Bitcoin reaching $79,760 before falling 2.49% to $77,770 14 hours later. The retreat tested the $77.9k local support area and triggered $269.96 million in long liquidations and $116.62 million in short liquidations, the highest one-day total in nearly a week. Spot Bitcoin ETF demand also weakened, with $166.8 million in combined outflows over the previous two trading days, according to Farside Investors. AMBCrypto reported that long-term holders were taking profits, potentially adding to short-term selling pressure. Bitcoin's $76k demand zone held, while the $76k-$82k range remains a key battleground because 35% of supply was accumulated at that level or higher. The retreat also formed part of a wider market decline linked to higher oil prices and fears of faster inflation, while the probability of a U.S. Federal Reserve rate hike reached 60.2%. Despite the pullback, Bitcoin retained a bullish four-hour structure after last week's move to $82,300. A fall below $76,264 would turn that structure bearish. The one-week liquidation heatmap identified $77.4k as the nearest and densest magnetic zone, with $79.7k, $80.5k and $82k as higher levels to watch.
