Bitcoin enters the final stretch of August with strong momentum after posting its largest weekly dollar gain in history, climbing $14,264 to close at $77,387, a gain of 22.7% in seven days. The rally has placed the psychologically important $80,000 level squarely in focus, with traders now monitoring whether spot demand can hold the breakout above former resistance near $70,500.
The move comes amid growing signs that traditional fixed-income markets are losing their anchoring power. KuCoin reported that U.S. bond buybacks have failed to stabilize yields, prompting a notable rotation of capital into alternative assets such as Bitcoin and gold. Both Bitcoin and gold have rallied roughly 10% over the past month, according to KuCoin, as traders search for safe havens during market turbulence. The shift accelerated after the U.S. Treasury Department expanded its buyback program, a move that initially aimed to support government debt markets but instead reinforced demand for scarce assets.
Institutional flows show that Bitcoin's advance is not solely a leverage-driven move. U.S. spot Bitcoin ETFs attracted $1.92 billion in net inflows during the trading week ended Aug. 21, according to SoSoValue data, marking the strongest weekly inflow total since October 2025. Market sentiment has also improved sharply: the Crypto Fear & Greed Index rose to 78, its highest level since December 2024. Strive Chairman and CEO Matt Cole noted that Bitcoin has strengthened against both the U.S. dollar and gold, with the BTC-to-gold ratio reaching 16.73 ounces of gold per Bitcoin, its highest level since May. Cole said demand for limited-supply assets could remain resilient even if short-term pullbacks occur.
Analysts caution that $80,000 is the main near-term target and a potential battleground. BTC Markets analyst Rachael Lucas said market participants should monitor ETF flows, spot volume, funding rates, and open interest to determine whether the rally is supported by real demand or excessive leverage. Zeus Research analyst Dominick John said Bitcoin could push toward $85,000 to $90,000 if ETF inflows and market liquidity remain supportive, while a stronger U.S. dollar or higher leverage could trigger a pullback. Trader That Martini Guy described the market structure as bullish while Bitcoin holds above its prior range, identifying $79,500 as the next key resistance before the $80,000 mark.
