Bitcoin rose 23.5% weekly: long and short game at the 80,000 mark and institutional differences

According to Woofun AI, after experiencing a round of sharp fluctuations, Bitcoin is currently fiercely contesting the $80,000 mark, and the market focus has quickly shifted to the digestibility of the $81,000 to $86,000 key supply area. Despite short-term pressure on prices, the historical increase recorded previously has laid a solid foundation for the current market. The outcome of the game between long and short in this region will directly determine the future direction of the market.

Looking back at the week of August 17-23, the price of Bitcoin soared from $62,818 to $77,593, with a weekly increase of up to $14,775, the biggest weekly increase in the absolute value of the dollar in 840 weeks since July 2010. Although the 23.5% increase in percent is only 41st in the historical rankings, it is the highest level since March 2023. As the Bitcoin price base continues to rise, even if the percentage increase is not an historical extreme value, the corresponding increase in the dollar amount reached an unprecedented scale.

As of August 28, after a brief break above $81,500, Bitcoin showed a pullback and regained repeated tug-of-war around $80,000. The flow of funds in US spot Bitcoin ETFs has become a core variable in judging the sustainability of this round of gains. For eight consecutive trading days from August 17 to 26, ETF net inflows totaled US$2,801.9 billion; the cumulative net inflow for August 26 was approximately US$3.282 billion. Glassnode divided this round of the market into two stages: the short liquidation on August 19 triggered an initial rise, then ETF subscriptions, falling exchange balances, and increased holdings of wallets of all sizes provided continuous spot funding support.

Data compiled by Woofun AI shows that between August 14 and 25, BTC-denominated open futures contracts fell from 645,760 BTC to 587,584 BTC, a drop of about 9.0%, hitting a five-month low. In the same period, open contracts using crypto assets such as BTC as margin fell to around 52,000 BTC, accounting for 11% of open futures contracts, indicating that cash and stablecoin margins already dominate.

Furthermore, perpetual contract funding rates remained at a neutral level for most of the time, indicating that liquidated bears were not immediately replaced by large numbers of leveraged bulls. Taken together, this round of growth has real funding. The 80,000 US dollar is still under stress testing. The short-term dispute focuses on whether the $81,000 to $86,000 supply area can be effectively digested, while the medium-term dispute is whether the current round of market is a cyclical reversal or a quick recovery within the bear market framework.

On-chain chip distribution and order book data further revealed the strength of resistance in the $8.1 million to $86,000 range. The data shows that the $80,000 position is forming one of the densest resistance zones in Bitcoin's history. In the $80,000-$82,000 range, close to 8% of the Bitcoin circulation supply was gathered, with around 5% of the chips concentrated at the price of $80,000 alone, the highest of all price levels.

This means that once the price of the currency returns to the region, a large number of investors who have previously bought will return to the cost line, which may trigger concentrated sell-off and form a so-called “supply wall.” $78,000 is also an important node, holding around 3.7% of the supply, while $82,000 is the fourth most intensive price point. These investors, who opened positions during the 2024-2025 upward phase, are now waiting for an opportunity to break the deal after experiencing a price correction from the end of 2025 to the beginning of 2026. Historical experience shows that when the price returns to the turnover range of a large number of chips, the selling behavior of short-term holders often amplifies the resistance effect. Metrics tracked separately by Glassnode show that the average cost of holding a US spot Bitcoin ETF also falls within the $80,000 to $82,000 range.

Since ETFs are currently one of the most important sources of incremental capital in the market, the behavior of their holders has a significant impact on prices. When the price of the currency is close to this 'break-even line', some institutional or retail investors may choose to redeem or sell, further increasing the selling pressure in the region. On the technical side, Bitcoin is currently still below the 50-week moving average (currently around $81,081) and has not effectively recovered since November 2025. Looking back at history, in May 2020 and March 2023, Bitcoin began a bullish market that continued for several months after breaking through this long-term trend line. Therefore, whether it can currently stand above $81,000 is seen as a key sign of a strong or weak shift in the market in the medium term.

However, in the $60,000-$63,000 range, more than 6% of supply was also concentrated, but the region successfully turned into strong support for most of 2026. Analysts believe that Bitcoin is currently at a critical point in a long and short game. If bulls can use incremental capital to effectively break through the “triple resistance zone” of $80,000 to $82,000 and stabilize the 50-week EMA, it may open up room to move towards higher prices and repeat the historical bull market script after breaking through the long-term moving average. Conversely, multiple upside failures could trigger panic selling by short-term holders, causing the price to fall back to the $75,000 or lower support range to find balance.

In terms of macroeconomic research, major institutions clearly disagree on seasonal effects and cyclical positioning. CryptoQuant Research notes that September has long been one of the weakest months for US stocks, with an average return of around -0.8% for the past 50 years for the S&P 500. Bitcoin recorded negative returns in September for six consecutive years from 2017 to 2022, but closed higher in September for three consecutive years in 2023, 2024, and 2025, and this seasonal pattern is weakening. The 2026 midterm election uncertainty, compounded by the US midterm elections, could drive up volatility and encourage investors to lower their risk exposure.

The core question is whether seasonal adjustments will evolve into widespread risk aversion, and we need to focus on ETF capital flows and spot BTC demand. If risk aversion spreads throughout the market, Bitcoin will be under pressure; conversely, if ETF and spot demand remains strong, the traditional September model may be broken again. K33 Research believes that BTC returned to the 50-day, 100-day, 200-day, and 200-week EMAs within four days. K33 sees January and October 2023 as the closest historical reference, believing that record shortfall, resumption of trading activity, and scarce asset rotation are similar to the early stages of past cyclical bull markets.

CoinShares said that the low point in the current cycle may have already appeared, and it is more likely to maintain the range for the next two to three months. BTC may be close to $80,000, but it is harder to keep above that position; moving towards $100,000 for a longer period requires further weakening employment data and driving the market to significantly lower interest rate expectations. Bitwise Europe, on the other hand, pointed out that Bitcoin's bottom structure has entered a later stage. Continuing to stand at the $69,000 short-term holder cost line will improve the local market structure; breaking through and maintaining the real market average of 76,000 US dollars under the simultaneous improvement of capital flow and market participation will confirm the return of macro risk appetite and mark the end of the bear market.

The views of traders and 'smart money' focus more on short-term goals and entry strategies. A well-known trader proposed a strategy of 'setting 10 big targets', saying that they had indirectly returned two-thirds of their positions in the $78,000 to $79,800 area, and thought it would be difficult to see a decent pullback before $100,000; $100,000 would arrive soon. MN Capital founder and CIO Michaël van de Poppe said that the upward trend is likely to continue longer than expected, and Bitcoin is expected to push up to at least $82,700, and possibly $90,000. He pointed out that Bitcoin is currently in a pretty good consolidation range, and given the current upward momentum, another test of the high seems inevitable.

Meanwhile, he suggests anything under $74,000 is an excellent entry opportunity. Together, these views reflect that after experiencing a sharp rise in the market, short-term participants tend to take a dip in the pullback, while mid-tier investors are closely watching breakthroughs in key resistance levels to confirm the starting signal for the next wave of markets.
