<div id="readability-page-1" class="page"><div><div>Author: hyphin Source: onchaintimes Translation: Shan Ouba, Jinse FinanceFor the past decade, Bitcoin's market capitalization percentage has been charted as an asset. It has market codes, trend lines, cyclical narratives, and a plethora of macroeconomic interpretations, almost bordering on a niche belief. But it lacks a legitimate trading market and a universally accepted base for calculation.When market capitalization percentage was merely market data, this ambiguity was acceptable. No one used it for financial settlements, so an imprecise chart was irrelevant. Once traders can express their opinions, ambiguity becomes collateral damage. Every product must answer a question that charts can avoid: What constitutes the overall market?The crypto market can openly discuss this question because token supply is transparent enough to be verified, audited, and ultimately traded. In 2026, the truly valuable answer won't be the addition of a new centralized perpetual contract, but rather the emergence of on-chain trading platforms—they've turned the computational method itself into a product. Market capitalization percentage is tradable because its definition must first be clearly defined. Key Takeaways: Currently, the Bitcoin market capitalization percentage (BTC.D) charts on major trading platforms are only 25 basis points behind those of tradable oracles—TradingView's data is close to that of Paragon and Domination, while CoinGecko's broad market capitalization definition is 268 basis points lower. The inclusion of stablecoins alone would cause the current BTC.D value to change by approximately 690 basis points; during the bear market following the LUNA crash in June 2022, this difference peaked at 854 basis points, making it the largest hidden influencing factor in the calculation. Since 2020, the correlation between BTC.D and the Bitcoin spot price has reversed 87 times—this closely watched price line is not a simple substitute indicator for Bitcoin's price trend. Tether's market capitalization share (USDT.D) peaked at 9.28% during the week of the FTX crash, representing the purest risk appetite signal formed within the market, driven by overall market capitalization contraction, not by the issuance of new Tether tokens. The True Meaning of Market Cap Share Most excess returns in the crypto market are essentially just repackaged versions of overall market returns. Going long on mainstream cryptocurrencies, shorting altcoin portfolios, trading pairings with liquid public chains, and basis trading are all common operations. Market cap share is one of the few purely relative value indicators in the market. It doesn't ask whether Bitcoin is rising or falling, only whether Bitcoin's share in the overall market is increasing or decreasing—the difference seems small on paper, but it's enormous over a long time frame. Simply put, comparing Bitcoin's quarterly return with the quarterly trend of BTC.D clearly shows the difference: no leverage, no borrowing costs, no product replication required; just by comparing this closely watched price line, you can see the market trend it reflects. <img src="https://imageproxy.pbkrs.com/https://img.jinse.com.cn/7469703_watermarknone.png?x-oss-process=image/auto-orient,1/interlace,1/resize,w_1440,h_1440/quality,q_95/format,jpg" width="600" height="374" original-src="https://imageproxy.pbkrs.com/https://img.jinse.com.cn/7469703_watermarknone.png"/>Data source: CoinGecko, TradingViewThe data for 2021 and 2022 is extremely dramatic: during the 2021 bull market, BTC.D fell for all four quarters of the year; in 2022, while Bitcoin prices plummeted, BTC.D rose for three quarters. This divergence reappeared in a more moderate form in 2025, with Bitcoin falling 4.5% for the year, while its market capitalization share increased by 2.6%. In 12 out of 26 quarters since 2020, the two trends have been completely opposite. Holding Bitcoin and trading Bitcoin market share are fundamentally different investment logics. <img src="https://imageproxy.pbkrs.com/https://img.jinse.com.cn/7469704_watermarknone.png?x-oss-process=image/auto-orient,1/interlace,1/resize,w_1440,h_1440/quality,q_95/format,jpg" width="600" height="397" original-src="https://imageproxy.pbkrs.com/https://img.jinse.com.cn/7469704_watermarknone.png"/>Data source: CoinGecko, TradingViewStatistical data shows that the 90-day rolling correlation between Bitcoin market capitalization share and spot price has reversed 87 times over the past period. This data indicates that market capitalization share is not always inversely related to Bitcoin price; rather, the relationship between the two is extremely unstable and cannot be regarded as a simple substitute indicator for Bitcoin price. This instability means that BTC.D is just one form of market capitalization percentage trading, not the whole picture. Tether's market capitalization percentage (USDT.D), on the other hand, is a purer, more fundamental indicator of risk appetite, formed internally within the market. During market panic, Tether's circulating supply typically doesn't change significantly; instead, the prices of all other crypto assets collectively decline. <img src="https://imageproxy.pbkrs.com/https://img.jinse.com.cn/7469705_watermarknone.png?x-oss-process=image/auto-orient,1/interlace,1/resize,w_1440,h_1440/quality,q_95/format,jpg" width="600" height="416" original-src="https://imageproxy.pbkrs.com/https://img.jinse.com.cn/7469705_watermarknone.png"/>Data source: TradingView, CoinGeckoThe most obvious peak in the data appeared during the FTX crash week: in November 2022, Tether's market capitalization share surged to 9.28%, just days after Alameda's balance sheet was exposed. This increase was not due to Tether issuing new coins, but rather to the overall market capitalization contraction. Stablecoin supply is relatively more rigid than crypto assets; when Bitcoin and altcoin prices collectively fall, the share of stablecoins passively increases. The asset decline during panic directly generated this clear signal. A platform offering five market capitalization percentage trading pairs addresses a significantly different issue than one offering only one. Market capitalization percentage is a broader market metric, not just a single Bitcoin price line. The Basis Computation Dilemma: TradingView, Domination Finance, and Paragon's market capitalization percentage calculations are highly similar, while CoinGecko's broad market capitalization calculation deviates considerably. Recent data shows TradingView is only 25 basis points behind the two tradable oracles, while CoinGecko is 268 basis points behind. The discrepancy in the numerator (Bitcoin supply) is almost negligible: Bitcoin supply is clear and transparent, prices on major exchanges are highly convergent, and the remaining minor differences are only measured in basis points. The real key is not in the numerator, but in the denominator—the overall market capitalization. It is not a simple parameter, but the core of the product. While the overall market capitalization may seem like a fixed value, its definition becomes crucial once it becomes a trading contract. Stablecoins are the single most influential variable. Including core USD stablecoins like Tether, USDC, DAI, BUSD, and USDS within the crypto asset category yields one value for BTC.D; considering them as idle off-exchange funds results in a different value. Currently, this single choice alone changes the value by nearly 7 percentage points; at its peak after the LUNA crash on June 19, 2022, this difference reached 854 basis points. <img src="https://imageproxy.pbkrs.com/https://img.jinse.com.cn/7469707_watermarknone.png?x-oss-process=image/auto-orient,1/interlace,1/resize,w_1440,h_1440/quality,q_95/format,jpg" width="600" height="419" original-src="https://imageproxy.pbkrs.com/https://img.jinse.com.cn/7469707_watermarknone.png"/>Data source: CoinGeckoBoth calculation methods have reasonable justifications: stablecoins are on-chain assets, excluding them would make the overall market capitalization calculation seem subjective and one-sided; however, stablecoins are essentially dollar-denominated debt, and including them in the same category as crypto assets such as SOL and DOGE would change the economic meaning of this ratio. The problem is not that there are different standards, but that the market chart rarely indicates the specific calculation rules.The definition of the market scope is equally crucial.CoinGecko tracks over 16,000 assets globally, while Domination Finance and Paragon select only the top 125 or 200 assets, employing platform-specific supply rules and clear settlement standards. TradingView's data is similar to these two, but it's only market observation data, not transaction settlement standards. Market capitalization must also consider liquidity: a large paper market capitalization is meaningless without actual trading value. Therefore, Domination Finance uses liquidity weighting rather than simple market capitalization weighting: oracles not only determine asset market capitalization but also consider whether it has actual transaction settlement value. This difference is even more pronounced for cryptocurrencies other than Bitcoin: Bitcoin has high liquidity, broad consensus, and high fault tolerance; for cryptocurrencies with lower market capitalization rankings, factors such as circulating supply, cross-chain assets, trading platform coverage, and liquidity weighting directly affect the calculation results. The design differences between Domination Finance and Paragon are greater than the current numerical differences: their coin selection, weighting, supply sources, and exclusion rules differ, yet their latest calculations are almost identical. While TradingView's data is referential, it lacks trading authority—the trend line approximates the market line, but the price target is not, because &#34;approximate&#34; does not equal &#34;settlement-ready.&#34; The real difference lies in the market line used only for analysis versus the calculation method used for trading. From synthetic exposure to native products: Market capitalization percentages lack a spot market; there are no physical assets available for delivery and settlement; all transactions rely on index calculation methods. Previously, the only viable trading method was to go long on Bitcoin and short on altcoin portfolios. Traders had to manage their own coin composition, borrowing costs, regular rebalancing, derivatives rules, and stablecoin definitions—essentially operating an amateur index fund without any fees. This productization requires two conditions to be met: A well-developed oracle infrastructure capable of publishing standardized indices that include input data, fallback rules, anomaly checks, and execution paths; and traders accepting synthetic exposure settlements—accepting a value that cannot be exchanged for physical goods as the basis for transactions. The reason market capitalization percentage is a native crypto product is not primarily due to the ratio itself. Traditional finance uses similar indicators such as industry weighting, index weighting, free float adjustment, and ETF fund flows; the ambiguity of the denominator is not unique to crypto. However, the crypto market has a 24/7 public ledger where supply, cross-chain assets, currency composition, and exclusion rules can all be publicly verified. While not perfect, it is completely transparent. Binance once launched BTCDOM, a Bitcoin vs. altcoin trading product, but its core features are platform authority, a closed index, and a single market, which are not the same concept as the market capitalization share discussed in this article. The two current mainstream native products are essentially two solutions to the &#34;reliable calculation method&#34;: Data Source: Domination Finance, Paragon. Domination Finance: Hardening Calculation Rules. It discloses the denominator, uses liquidity weighting, removes derivatives, and builds an on-chain settlement vault. The vault is not a patch for insufficient liquidity, but a core design feature—for markets with no naturally traded underlying assets, the vault guarantees transaction settlement. Paragon: Market Pricing Index The index calculation logic relies on Hyperliquid's HIP-3 technology, incorporating market capitalization percentages into a central limit order book, with prices determined by market trading. The two platforms, using different mechanisms, yielded highly similar results, as did TradingView data. This could be due to independent verification, coincidence, or more likely, the inevitable result of objective constraints: when market scope, supply, and liquidity weights are clearly defined, compliant calculation methods are few and far between. When funds trade around market capitalization percentages, once-famous price charts become mere background noise; oracles used for transaction settlement are the true market. Trading Contracts When the market structure remains merely at the chart level, controlling the market structure is effortless. You can define boundaries, argue about cycles, without questioning the denominator. The tradable market structure disrupts this convenience. Those institutions that made it a reality did the tedious work first. They defined the market, published the methodology, and allowed funds to trade based on the results. The boundaries people focus on may be close to the market, and perhaps even useful. But closeness doesn't guarantee the final outcome. The core of contracts lies in the methodology.</div></div></div>

Bitcoin's market capitalization share (BTC.D) is a critical metric that reflects its relative value in the crypto market, distinct from its price. The correlation between BTC.D and Bitcoin's spot price has reversed 87 times since 2020, indicating instability. The market capitalization share is influenced by factors like stablecoin inclusion and overall market conditions, making it a unique indicator of market trends. Tether's market capitalization share (USDT.D) serves as a fundamental risk appetite signal, particularly during market downturns, highlighting the differences in investment logic between holding Bitcoin and trading its market share.

- The article discusses the complexity of Bitcoin's market capitalization percentage (BTC.D) and its implications for trading, emphasizing that ambiguous definitions hinder its effectiveness.  
- It highlights the necessity of a clear market structure and calculation method for BTC.D, as well as for trading platforms to leverage on-chain trading for accurate assessments.  
- The instability of the BTC.D in relation to Bitcoin's price, influenced by factors like stablecoin dominance, suggests the need for a robust framework to facilitate meaningful market participation.
