[In-depth] Bitcoin $78,000 seesaw battle: a triple game of rising inflation, Friday options expiry, and institutional support

📊 Background: On August 26, the U.S. July core PCE inflation index rose 3.7% year over year, higher than the expected 3.6% (Source: U.S. Bureau of Economic Analysis, BEA). The U.S. dollar strengthened, gold fell below $4,600 per ounce, and risk assets collectively declined—Bitcoin subsequently lost the $78,000 level (Source: Cointelegraph, August 26). Fed Chair Powell will deliver remarks at the Jackson Hole symposium on Friday, with market expectations for rate cuts cooling.

🔍 The triple game:
1️⃣ Macros: Inflation is still close to twice the 2% target, weighing on the near term.
2️⃣ Derivatives: About 81,700 Bitcoin options on Deribit (around $6.4 billion in notional value) expire on August 28 at 08:00 UTC. Call option open interest is concentrated at two strike levels: 75,000 and 80,000 (Source: CryptoSlate). Hedging by market makers could keep prices hovering, and it may also amplify a breakout.
3️⃣ Institutional: Bernstein’s latest report expects Bitcoin to return to $125,000 by the end of 2026. The cycle peak in 2029 could be around $300,000, and in a bull-market scenario about $500,000 (Source: Cointelegraph, August 26).

💡 View: In the short term, there’s a double squeeze from “inflation + options expiry,” while in the long term, historical-level support comes from institutional buying. Bernstein noted that this round of pullback occurred after a retreat of roughly 50% from the October peak, followed by a 28% rebound over the next 10 days—and because corporate and institutional buyers entered the market, the drawdown has been far shallower than the 75%–90% depth seen in prior cycles. Retail traders see a break below $78,000; institutions see “the asset being repriced.”

🎯 Recommendations:
1️⃣ Before the options settlement is finalized, don’t chase or cut positions aggressively within a narrow trading range—wait for clarity on August 28.
2️⃣ Keep a close watch on tonight’s Nvidia earnings and Friday’s Jackson Hole remarks; event-driven catalysts may amplify volatility.
3️⃣ Long-term investors can monitor institutions’ “buy-the-dip” absorption, but be sure to tightly control position sizing and risk.
