- Bitcoin gained 22.7% weekly, adding a record $14,264 to close at $77,387.
- U.S. spot Bitcoin ETFs drew $1.92B weekly, the strongest inflows since Oct. 2025.
- BTC faces $80K resistance as RSI hits 71.6 and Fear & Greed climbs to 78.
Bitcoin’s record weekly gain has pushed BTC into a fresh decision zone after the cryptocurrency added $14,264 in seven days and closed the week at $77,387. The 22.7% advance was the largest dollar-denominated weekly increase in Bitcoin’s history.
The move began after the U.S. Treasury doubled planned liquidity-support buybacks for longer-dated debt from $2 billion to at least $4 billion per operation, while renewed demand through U.S. spot Bitcoin exchange-traded funds added another source of buying.
Bitcoin Weekly Gain Was Fueled by ETFs and Short Covering
U.S. spot Bitcoin ETFs recorded $1.92 billion in net inflows during the trading week ended Aug. 21, their strongest weekly total since October 2025. That flow showed solid proof of institutional demand alongside the price advance.
However, derivatives also played a major role. Nearly $3 billion in crypto positions were liquidated during the initial surge, with about $2.74 billion coming from shorts. Shorts accounted for roughly 92% of the liquidation total, indicating that forced buying amplified the rally following the Treasury catalyst.
That scenario leads traders to watch whether fresh spot demand can replace the mechanical buying triggered by liquidations. CryptoQuant data cited during the rally also showed a rebound in spot demand, while ETF flows provided another measure of direct buying.
BTC Tests $80K as Momentum Becomes Extended
Bitcoin traded near $77,385.73 at the time of writing, recording a gain of 1.09% over the past 24 hours. Short-term technical data placed support near $75,450 and resistance around $79,300, with $80,000 remaining the main positive test.
The same data placed the relative strength index near 71.6, above the 70 overbought threshold, while the Crypto Fear & Greed Index stood at 78. Both measurements reflected how rapidly momentum strengthened during the weekly advance.
Strive Forecast Faces a Market Confirmation Test
Strive CEO Matt Cole said Bitcoin’s breakout against both the dollar and gold supports his forecast that the next cycle could be the “strongest” yet. The Bitcoin-to-gold ratio reached 16.73 ounces, its highest level since May.
For the bullish case, ongoing ETF inflows and continued spot demand would support another attempt at $80,000. Zeus Research analyst Dominick John identified 85,000-90,000 as the next area if that breakout holds, with $100,000 possible if ETF flows and macro liquidity remain supportive.
