The short version
- BTC hit roughly $77,700 on August 21, with an intraday peak of $79,400 per CryptoNews.net.
- The near-24% weekly gain was Bitcoin's biggest since at least March 2023, though different outlets describe the comparison period differently.
- Short sellers absorbed $1.06 billion in forced liquidations out of $1.25 billion total over 24 hours.
- Altcoins rose — XRP led at +19% — but Bitcoin's market dominance climbed to nearly 60%.
Bitcoin Breaks $77,000 After a Near-24% Weekly Surge
On August 21, Bitcoin crossed $77,000 for the first time in months. CoinGecko data, as tracked by Yahoo Finance, placed the coin at roughly $77,700 during the session. The intraday peak reached $79,400 according to CryptoNews.net, though the price pulled back toward $75,500 by later in the day. The live Bitcoin price on this site reflects those moves as they happen.
The move built across five trading sessions. Starting from around the $62,000 range on Monday August 17, Bitcoin gained nearly 24% by Thursday's close, according to CoinGecko figures cited by Yahoo Finance. CNBC reported the weekly gain at 23% — close enough that the gap comes down to whether analysts measure a rolling seven-day window or a calendar week starting Sunday.
That scale of weekly gain is genuinely rare. CryptoNews.net, relaying CoinDesk reporting, called it Bitcoin's strongest weekly advance since March 2023 — more than three years back. Bloomberg's headline described it as the biggest gain in 'more than two years,' a different framing of the same event. CNBC's language matched CoinDesk's 'since 2023' reading most closely.

A Treasury Announcement and ETF Cash Lit the Fuse
Market participants pointed to a U.S. Treasury bond buyback announcement as the catalyst, though that link rests on timing correlation rather than direct proof. The announcement was read as a sign of easier financial conditions. On Monday August 17 alone — the first full trading session after the news — Bitcoin spot ETFs logged $297.5 million in net inflows, per CryptoNews.net. The Bitcoin ETF explainer covers how those funds work.
Spot ETFs work as a direct pipeline between traditional finance and Bitcoin's order books. When institutions send cash into these funds, the managers must buy actual Bitcoin on the open market, which pushes prices up. The $297.5 million figure covers that one Monday alone; the full week's tally would be larger, but the single-day number signals that institutional buyers stepped in early and with force.
Correlation is not causation, and Bitcoin's rally likely had several simultaneous drivers. Momentum traders chasing a breakout, technical buyers responding to a chart pattern, and short sellers forced to buy back their positions at higher prices can all push price in the same direction at once. Attributing the move to any single trigger oversimplifies a market where many participants act on different signals.

The Chart Pattern That Called $76,000 Proved Accurate
Before the rally, chart analysts had identified an inverse head-and-shoulders pattern in Bitcoin's price since the June lows. In that formation, two smaller price dips — the shoulders — flank a deeper dip called the head. When price breaks above the neckline, the level connecting the two shoulder peaks, the pattern implies a further rise roughly equal to the depth of the head. CryptoNews.net reported the implied target at $76,000, and Bitcoin cleared it during the week.
Technical analysis is interpretation, not physics. Two chartists examining the same data can draw different patterns and reach different conclusions. The inverse head-and-shoulders call is notable mainly because the price reached the cited target, not because the shape itself caused the move. When many traders watch the same price levels, their buying near those targets can become self-fulfilling. Bitcoin's historical volatility tool shows how quickly these setups resolve in either direction.
The pattern built over roughly two months, giving analysts time to form a view well before the breakout. A neckline in this context is a price ceiling that Bitcoin tested and failed to break through multiple times. Each failed attempt added weight to the eventual break. Once Bitcoin closed convincingly above that ceiling, the measured target of $76,000 served as the near-term roadmap — and the week's price action delivered on it.
Compare the wider Bitcoin and crypto market
A Billion Dollars in Short Bets Got Wiped Out in 24 Hours
As Bitcoin climbed, traders who had bet on a price decline faced automatic liquidations — forced closures that exchanges trigger when a position's losses reach a preset threshold. Over the 24 hours ending around August 21, the market processed $1.25 billion in total liquidations, according to CryptoNews.net. Of that amount, $1.06 billion came from short positions and only $178 million from long positions.
The long-short account ratio stood at 0.865, meaning more individual accounts held short bets than long ones, even as the price rose sharply. This is a contrarian setup: a majority of leveraged accounts expected lower prices while the market moved against them. When short sellers are forced to buy Bitcoin back to close their positions, those purchases add more buying pressure and accelerate the very move that hurt them.
This dynamic is called a short squeeze, and it can self-reinforce without any change in Bitcoin's underlying fundamentals. It needs only a price move large enough to breach the liquidation thresholds that exchanges set. The Bitcoin markets overview captures open-interest and liquidation data for readers who want to track this kind of positioning. The billion-dollar scale in a single day shows how much leveraged short exposure had built up before the move.

Bitcoin's Strongest Week in Years Left It More Dominant Than Before
Several alternative cryptocurrencies posted meaningful gains in the same period. XRP rose approximately 19%, ENA gained 13%, ZEC climbed 12.5%, and both NEAR and LINK each added around 8%, according to CryptoNews.net. In dollar terms, holders of those coins made money. The rally did spread across the wider crypto market — just not equally across all assets.
The underlying data tells a more nuanced story. The Altcoin Season Index, which tracks how many of the top 100 coins outperform Bitcoin over a rolling period, fell from 36 to 33 that week — a reading below 50 means Bitcoin is beating most alternative coins. Bitcoin's market dominance rose to roughly 59.3–59.9%, per CryptoNews.net. More of the market's total capital moved into Bitcoin, not away from it.
A dollar-cost averaging backtest across crypto asset classes makes this distinction concrete. When Bitcoin's dominance rises during a rally, altcoins can gain in USD while still losing ground relative to BTC. Holders of XRP or ENA came out ahead in dollar terms, but they would have fared better holding Bitcoin outright. That is the accurate reading behind the claim that altcoins came along for the ride: they joined, but Bitcoin led.
