Bitcoin recorded its largest dollar-denominated weekly gain, adding $14,264 to close at $77,387, a 22.7% increase. U.S. spot Bitcoin ETFs attracted $1.92 billion in net inflows during the week ended Aug. 21, their strongest weekly total since October 2025. The rally followed expanded U.S. Treasury bond buybacks, weaker-dollar expectations, renewed institutional demand and short covering. Matt Cole, chairman and CEO of Bitcoin treasury company Strive, said Bitcoin's breakout against both the dollar and gold supports his view that the next cycle could be its strongest yet. He expects scarce assets to benefit over the next 12 to 18 months from potential dollar weakness, monetary debasement and rising demand in an AI-driven economy, while warning that Bitcoin could still experience a meaningful retracement.
