Bitcoin traded at $75,265 as of 05:23 UTC on August 21, 2026, according to Bitstamp data on TradingView, posting a gain of nearly 3% on the day after touching an intraday high of $75,700. The advance carried price action back above its major moving averages, with the 50-day, 100-day, and 200-day simple moving averages sitting near $64,500, $66,120, and $68,950, respectively. Those long-window averages are among the most widely followed trend gauges in technical analysis, and price holding above all three at once is conventionally read as a sign of a broadening uptrend rather than a countertrend bounce.

$73,200 emerges as the key level to defend

The breakout pushed decisively through the 0.618 Fibonacci retracement at $73,210 — the level flagged in the prior session's analysis as the nearest resistance — measured from the recent $57,700 swing low up to earlier highs. Fibonacci retracements, drawn horizontally between a swing low and a swing high, are among the most widely used support-and-resistance tools in crypto trading, and the 0.618 line — often called the golden ratio — is one of the most closely watched levels in the sequence. With that former ceiling now flipped into support, the focus shifts to whether bulls can defend it on a daily closing basis.

A slip back below $73,210 would leave the move exposed to a swift retracement, according to the technical setup. The first safety nets below sit at $70,250, the 0.5 Fibonacci level, and $67,280, the 0.382 retracement.

On the upside, the next clean barrier is the 0.786 retracement near $77,700. Clearing that level would open a runway toward reclaiming the low-$80,000 region.

The daily relative strength index (RSI), a momentum oscillator scored from 0 to 100 that measures the speed and magnitude of recent price changes, stands at 82.95, well beyond the traditional overbought marker of 70. While overbought readings do not guarantee an immediate reversal, the source analysis notes they typically favor a cooling-off period or a retest of support before Bitcoin makes its next attempt at $77,700.

Derivatives: short liquidations dominate

Beneath the spot price action, the derivatives market experienced an aggressive squeeze. CoinGlass data shows an enormous wave of liquidations, with short positions bearing the brunt of the damage. A liquidation occurs when an exchange forcibly closes a leveraged position because losses have exhausted the trader's margin; and because a short is closed out by buying the asset back at market price, waves of forced short covering add buying pressure — the dynamic commonly known as a short squeeze.

Over a 12-hour window, total liquidations reached $382.26 million, of which $363.58 million came from liquidated shorts against just $18.68 million in long liquidations. Across the broader 24-hour cycle, total liquidated positions climbed to $793.99 million, fueled by $753.51 million in short liquidations versus a mere $40.49 million in longs.

The scale of the imbalance indicates that the explosive drive past $75,000 was not purely organic spot buying, but was heavily accelerated by trapped bearish bets being forcefully closed out as the market surged.

ETF inflows stay positive but cool down

Farside Investors' Bitcoin ETF data recorded roughly $103 million in net inflows into U.S. spot Bitcoin funds on August 20, following a large haul of $517.2 million on August 19. U.S. spot Bitcoin ETFs, which the SEC approved in January 2024, have since become a primary regulated channel for institutional exposure to the asset, which is why their daily net flows are tracked widely as a proxy for that demand.

The figures confirm continued institutional accumulation through regulated products, although the pace slowed noticeably on the exact day Bitcoin extended its rally. That pattern suggests the latest push was driven largely by derivatives liquidations rather than a pure ETF squeeze, with broader crypto positioning and market momentum sharing the load.

The next U.S. trading session is expected to provide a clearer read. Another heavy inflow day would signal that fund allocators are chasing the breakout higher, whereas a flip to net outflows would leave the short-term trajectory more dependent on active market traders.

Macro and policy backdrop remains constructive

Bitcoin's broader recovery began after the U.S. Treasury announced plans to at least double the maximum size of select long-dated bond buyback operations. The Treasury reinstated regular buyback operations in 2024 as a liquidity-management tool for the U.S. government bond market, the largest and deepest in the world. That liquidity injection provided a tailwind for risk assets globally, while separate calls from Washington for Congress to prioritize crypto market structure added to the narrative.

The immediate test is not how quickly BTC can chase $80,000, but whether it can turn $73,200 into a concrete floor before challenging the next major wall at $77,700.
