Bitcoin was trading near $80,000 as spot Bitcoin ETF inflows, on-chain accumulation and short liquidations supported a rebound, while inflation pressure, oil-related geopolitical risks and caution ahead of Federal Reserve Chair Kevin Warsh's Jackson Hole keynote limited risk appetite. At 6:33 p.m. on Aug. 28, Bitcoin was $79,456 on Binance's USDT market, down about 0.41% from the previous day, and about $80,100 on Upbit. The kimchi premium, or the price gap between overseas and South Korean exchanges, was 0.87%. US spot Bitcoin ETFs recorded nine consecutive trading sessions of net inflows from Aug. 17 through Aug. 27, totaling $3.0442 billion. Glassnode said short positions accounted for 85% of liquidations during the rebound and identified the Aug. 19 move as the biggest single-day short squeeze since 2019; it also said ETFs attracted $2.23 billion during the rally. Bitcoin's 30-day accumulation trend remained above the neutral 0.5 level, although wallet flows diverged, with entities holding more than 100,000 BTC absorbing 59,100 BTC and those holding 1,000 to 10,000 BTC selling 50,500 BTC since June 30. Traders are focused on resistance between $81,700 and $83,000, including a potential two-session close above Bitfinex's $82,818 trigger, while support around $77,000 is viewed as important for preserving the rebound. The US personal consumption expenditures price index rose 3.7% year over year in July and core PCE rose 3.3%, both above the Federal Reserve's 2% target. CME FedWatch data on Aug. 28 showed a 66.2% chance of unchanged rates and a 33.8% chance of a hike in September. Analysts said Bitcoin has improved technically and has not yet entered an overheated zone, but its ability to clear low-$80,000 supply after the Jackson Hole speech remains the immediate test.
