From the perspectives of Bitcoin's market capitalization ratio (BTC/Gold Market Cap Ratio) and its exchange rate ratio (BTC/XAU), Bitcoin's valuation relative to gold has indeed fallen to a highly cost-effective cyclical bottom support zone, and the upside potential is significantly expanding. 1. Market Capitalization Ratio: Falling to a Strong 5% Support Zone Key Data Comparison: Bitcoin's price fluctuated between $76,000 and $78,000, with a total circulating market capitalization of approximately $1.52 trillion to $1.60 trillion USD; during the same period, spot gold prices were at a high of $4,100 to $4,150/ounce, and the total global above-ground gold reserves (approximately 216,000 to 220,000 tons) corresponded to a total market capitalization of $29.0 trillion to $30.2 trillion USD. **Market Share:** Bitcoin's market capitalization accounts for only about 5.0%–5.3% of the total gold market capitalization (if calculated as a "gold + Bitcoin" dual inflation-resistant value storage pool, BTC accounts for approximately 4.8%–5.0% of the entire pool). **Cyclical Coordinates:** At its cyclical high of $126,000 in 2024–2025, Bitcoin's share of gold's market capitalization once exceeded 9.5%–10%. With gold's continued bullish trend over the past year due to central bank purchases and geopolitical safe-haven demand, while Bitcoin underwent deep consolidation, this ratio has almost halved, reverting to its mean and precisely retracing to the central platform (around 5%) before the 2024 spot ETF surge. 2. **Exchange Rate Ratio (BTC/XAU):** Reaching a Key Structural Defense Line **Bitcoin to Gold Ounces:** Based on the latest prices, 1 BTC ≈ 18.5–19.0 ounces of gold. Technical and Cyclical Characteristics: At the top of the previous market cycle, 1 Bitcoin could be exchanged for approximately 35-37 ounces of gold. Past cycles show that when the BTC/XAU ratio retraces nearly 50% from its cycle high and falls back to the neckline of the previous cycle's breakout (i.e., the 18-20 ounce range, corresponding to the densely traded area near the all-time high in 2021), it often signifies that the "de-bubbling" of crypto assets relative to precious metals has been fully completed. 3. Why does this ratio range exhibit "bottoming-out" characteristics? Convergence of the Numerator and Denominator: Gold's market capitalization is approaching the $30 trillion mark. Limited by its extremely high market capitalization, the difficulty of marginal funds driving gold to double again is far greater than driving Bitcoin's $1.5 trillion market capitalization. When both face fiat currency credit dilution and global liquidity cycles simultaneously, a 5% relative market capitalization trough gives Bitcoin extremely high beta elasticity. Rebalancing Effect of Institutional Asset Allocation: In macro multi-asset portfolios, many institutions include both gold and Bitcoin in their "hard asset/digital gold" basket. When gold surges and Bitcoin corrects, causing the BTC weighting to passively compress to around 5%, the quarterly/annual rebalancing mechanisms of quantitative and macro funds naturally trigger cross-asset rotation by "taking profits on some gold and increasing allocation to low-priced Bitcoin." Sentiment and Liquidity Clearing: The continued weakness of BTC/XAU over the past year is essentially a result of funds crowding into the most certain traditional safe-haven asset (gold) under conditions of sustained high interest rates and macroeconomic uncertainty. When the relative ratio fell to the lower rail of the long-term upward channel, leveraged and short-term speculative positions in the market had been thoroughly cleared out. 4. Key Indicators for Bottom Confirmation and Right-Side Inflection Points While this area is undoubtedly a bottom from a relative valuation perspective, the transition from the "left-side bottom range" to the "right-side main upward wave" typically requires a liquidity catalyst: Real Interest Rates and Dollar Liquidity Inflection Points: Gold is more sensitive to geopolitical risks and central bank gold purchases, while Bitcoin is more sensitive to global narrow liquidity (Global M2) and expectations regarding the Federal Reserve's balance sheet. Once the Fed's rate-cutting path becomes clearer or long-term US Treasury yields decline, a rebound in risk appetite will be the first driver for the BTC/XAU ratio to turn upwards. Right-Side Confirmation Signals: Observe whether the BTC/XAU ratio can effectively stabilize above 21-22 ounces (corresponding to a market capitalization share rebounding to above 6.0%). Once this neckline is broken, it often signifies that cross-asset funds have officially shifted from a defensive stance in precious metals to an offensive stance in digital assets.
