Bitcoin staged one of its strongest advances of the year, climbing from below $65,000 on August 19 to an intraday peak near $79,463 before easing toward the $77,000 area. The move combined a powerful short squeeze with sustained institutional demand through U.S. spot exchange-traded funds and limited fresh leverage in derivatives markets.

Short Squeeze and Spot Buying Fuel the Breakout

The initial surge cleared resistance around $65,000 and triggered cascading liquidations of short positions. More than $1 billion in crypto shorts were forced closed within about an hour, with total short liquidations approaching $1.79 billion and broader market-wide figures reaching near $2.7 billion over 24 hours. Separate tallies placed crypto short liquidations above $4.3 billion from Wednesday through Friday.

Analysts at Bitfinex noted that while forced covering accelerated the advance, the character of the rally differed from typical leverage-driven moves. Bitcoin gained 10% to 11% during the breakout phase, yet aggregate open interest rose only about 4%. Spot purchases and returning institutional interest continued supporting prices after much of the short pressure had cleared.

Because open interest expanded far more slowly than price, the team concluded that spot accumulation and short covering performed most of the work. This reduced the immediate risk of a sharp reversal driven by overcrowded long positions. Bitfinex identified the $68,000–$69,000 zone as critical support, coinciding with the short-term holder cost basis and the 200-day moving averages, which Bitcoin reclaimed for the first time in roughly nine months.

ETF Inflows Provide Institutional Backbone

U.S. spot Bitcoin ETFs attracted substantial capital during the advance. Funds recorded approximately $517 million in net inflows on August 19, their strongest daily total since May, followed by about $606 million on August 20. The two-session total exceeded $1.1 billion, while the broader weekly intake reached $1.61 billion, putting the products on pace for their strongest week of 2026.

Continued inflows through regulated securities channels offered a direct measure of demand from U.S. brokerage and institutional accounts. Analysts said sustained ETF buying would help distinguish the rally from a purely temporary short-covering episode. Standard Chartered’s global head of digital asset research, Geoff Kendrick, observed that recovering ETF flows and relatively low open interest could allow more investors to re-enter as prices rise, noting for the first time this year a risk that his $100,000 year-end forecast could prove too conservative, with a possible retest of the prior record near $126,000.

Whale Sales and Overbought Conditions Introduce Caution

As Bitcoin approached $80,000, large holders began distributing. On-chain data showed one unidentified address sold 7,700 BTC valued at approximately $576.6 million over three days, including a single 2,700 BTC transaction worth about $211.8 million. Another wallet sold 550 BTC for roughly $39.43 million. These transfers increased available supply near a key resistance area after the rapid $15,000 two-day climb.

Technical measures also signaled stretched conditions. The four-hour Relative Strength Index climbed to 87 during the peak advance, while the Money Flow Index reached 100. The Crypto Fear and Greed Index swung from 34 (fear) the prior week to 71 (greed),illustrating how quickly sentiment shifted.

Market participants pointed to the $75,000–$76,000 range as an important near-term support band. Holding above that area, alongside the deeper $68,000–$69,000 zone, would keep the recovery intact. A decisive break lower could open the path toward $70,000–$72,000 if buying interest fades or further large sales emerge.

Macro Backdrop Offers Mixed Support

Macro developments added a favorable backdrop. The U.S. Treasury Department announced plans to at least double the maximum size of liquidity-support buybacks for longer-dated government securities, raising the cap from $2 billion to at least $4 billion per operation beginning September 9 through November 4. Long-term yields initially declined after the announcement, improving conditions for risk assets as Bitcoin moved through $70,000.

Bitfinex cautioned that renewed increases in Treasury yields, exhaustion of remaining short covering, and the movement of large volumes of profitable coins onto exchanges could still pressure the market. A significant wave of profit-taking remains a risk if holders choose to sell into strength.

Bitcoin traded near $77,000–$77,500 in recent sessions after the pullback from the $79,463 high. The combination of restrained leverage growth, robust ETF demand and improving liquidity conditions has given the advance more structural support than a pure squeeze, yet whale distribution and extreme momentum readings leave room for further consolidation or deeper retracement in the sessions ahead.
