Bitcoin Rallies 25% in August, but $81,000 Remains the Critical Battleground

Bitcoin recorded its strongest August since 2017 with a 25% gain, driven by U.S. Treasury buybacks, regulatory optimism, and significant short liquidations. While the trend has improved, analysts at 21Shares highlight that the $81,000 to $82,000 range serves as the decisive threshold to confirm a structural trend reversal rather than a bear market rally. Key indicators to watch in September include ETF inflows, long-term bond yields, and support levels between $76,000 and $78,000.
