Bitcoin Jumps Over 20% in Five Days, Stalls Just Below $80,000

Bitcoin (BTC) rallied more than 20% over the past five days—roughly the S&P 500’s typical annual return delivered about 140 times faster—before momentum faded near $79,500, just 0.6% shy of the $80,000 mark. BTC traded around $76,750 on Friday, up 6.6% on the session, leaving it about 4% below $80,000. The daily relative strength index (RSI) rose to 84.64, the highest reading seen in 2026. ### Why the move looks outsized versus stocks Using New York University's Stern School dataset, the S&P 500 has compounded at 10.02% per year since 1928, dividends included. Spread across five days, that equates to about 0.137%. Bitcoin's roughly 20% gain over the same window works out to about 140 times the pace. From trough to peak, the advance reached roughly 27%, putting BTC on track for its strongest weekly close in two years. Even so, the surge hasn't erased prior losses. Bitcoin remains about 39% below its all-time high of $126,080 set in October 2025. ### Macro catalyst and positioning unwind A key catalyst came from Washington. The U.S. Treasury said on August 19 it would at least double its long-end bond buybacks from $2 billion per operation to $4 billion, targeting 10-year to 30-year maturities. The program runs from September 9 through November 4. The announcement arrived as long-term yields had just touched 20-year highs, and bond desks viewed the move as a backstop. The rally also fed on forced positioning. Bearish traders took a reported $1.06 billion hit in a single day as short positions were unwound. Spot demand strengthened as well: U.S. spot Bitcoin ETFs recorded inflows of $517.2 million on August 19 and $606.3 million on August 20, the largest daily tally in August, according to Farside Investors. ### Three resistance levels sit between BTC and $80,000 Friday's candle opened at $73,027 and pushed up to $79,500 before sellers stepped in. That high aligned with a rising trendline drawn from February lows. Bitcoin climbed along the line through spring, broke below it during June's slide to $58,000, then failed after reclaiming the line from underneath—turning former support into resistance. Two additional hurdles cluster in the same zone: $79,427, which capped May's high, and the round-number $80,000 level just above it. On the downside, initial support is near Friday's $73,027 open. ### Weekend setup: consolidation favored over a clean breakout Helios Analytics' Jamie Coutts assessed the move against the prior calm in volatility, ranking it as the fifth-largest jump since 2018. Reviewing 14 comparable episodes, he found Bitcoin traded higher 30 and 90 days later 71% of the time, with a median gain near 10%. By comparison, a random day since 2018 averaged a 1.2% return. Outcomes have varied widely. A similar surge in April 2019 preceded a 118.7% gain over 90 days, while one in October 2019 was followed by a 23% decline over 30 days. Coutts noted the sample is small and his significance tests were not conclusive. In the median case, BTC also dipped 8.4% below entry within 90 days. "There is a wall of overhead supply at the low $80k range it needs to work through," Coutts wrote. On-chain signals have been more constructive. CryptoQuant data shows spot and futures demand turning positive together for the first time since October 2025. Another quicktake linked the rebound to the MVRV metric, which compares market price with the average holder cost basis. Analyst Darkfost estimated net new demand at a 2026 high of 25,000 BTC, comparing new coins with coins that have been idle for more than a year. CryptoQuant founder and CEO Ki Young Ju said the rally suggests a cycle low may be in place: "BTC looking strong here. Rallies like this in bear markets usually signal the bottom is in. Might see a dip, but the bear phase is pretty much done imo." Can Bitcoin tag $80,000 this weekend? It's possible but not the base case. Weekend liquidity is typically thinner, with fewer large buyers active on Saturday and Sunday. Clearing multiple resistance layers with RSI at 84.64—an overbought reading—likely requires meaningful size. A pullback toward $73,000 could cool momentum without negating the week's advance. Longer term, attention is shifting to whether supply in the low $80,000s gives way.
