As of July 21, the latest data shows that the Bitcoin market dominance (BTC.D) is at 60.95%, a significant drop of 5.66% over the past week. This key indicator has fallen below the long-term support level of 62.20%, reaching its lowest level since April, marking a new phase in the rotation of funds within the cryptocurrency market.
Dominance Rate Anomaly: Technical Indicators Release Strong Bearish Signals
Bitcoin dominance measures Bitcoin’s share of the total cryptocurrency market capitalization and is a key dashboard for observing market capital flow. This week’s crash is not an isolated event but the result of multiple technical signals resonating:
- Key Support Broken: The 62.20% support level has been solid since April 2025, and its breach confirms a trend reversal.
- MACD Indicator Deterioration: The MACD line has dropped to -0.61, significantly below the signal line (-0.24), with the histogram continuously expanding into the negative zone, indicating strong downward inertia.
- Historical Resistance Reappears: The dominance rate encountered the same technical resistance as at the end of 2020 when it peaked at 65% in early July, subsequently forming a classic bearish candlestick pattern.
This round of decline occurred in Bitcoin price Still stable at the high level of $118,500, indicating that funds have not withdrawn from the cryptocurrency market, but instead have massively shifted towards alternative assets.
Capital Migration: The Capital Absorption Effect of Altcoin Market
As Bitcoin’s dominance declines, market funds are rapidly flowing into other crypto assets, creating a stark contrast:
- Differentiated Growth in Overall Market Value
- Total crypto market cap increased by 4.35% weekly
- Total market cap excluding Bitcoin (TOTAL2) surged by 15.13%
- Total market cap excluding Bitcoin and Ethereum (TOTAL3) rose by 11.03%
- Ethereum Leads the Altcoins
Ethereum broke through $3,800, hitting a seven-month high, with an increase of over 20% in just July, and a market cap growth of $150 billion. This wave of market activity triggered one of the largest short squeezes in crypto history; according to Kobeissi Letter analysis, a further 10% price increase could trigger an additional $1 billion in short liquidations. - Rise of Layer 1 Protocols and Altcoins
Tokens like ADA, BNB, and SOL significantly outperformed Bitcoin, with the altcoin season index rising to 39 (the highest since February). Analysts observed that the flow of funds exhibited a classic rotation pattern: Bitcoin → Ethereum → Large-cap Altcoins → Small-cap Assets.
Regulation and Institutions: Profound Changes in Market Structure
Behind this change in dominance rate is a qualitative transformation of the underlying structure of the cryptocurrency market:
- Institutional Position Restructuring: The number of Bitcoin holdings by listed companies has surged, with over 265 companies holding approximately 3.5 million BTC (16% of circulation), doubling since early June. MicroStrategy’s holdings have surpassed $71.4 billion in value, with unrealized gains exceeding $28.5 billion.
- US Crypto Legislation Breakthrough: The House has passed three key bills: the "GENIUS Act" (stablecoin regulation), the "CLARITY Act" (asset classification), and the "Anti-CBDC Act". The GENIUS Act is expected to be signed into law by Trump on July 21, providing a clear entry channel for institutional funds.
- Bitcoin Enters National Strategy: The US, China, the UK, and other countries establish strategic Bitcoin reserves, El Salvador insists on the "Daily Purchase of 1 BTC" policy, Ukraine is legislating to include Bitcoin in its national reserves, and the competition for national holdings is intensifying.
Critical Point: Countdown to Altcoin Season
Historical patterns are repeating key signals:
- Cycle Similarity: The US Dollar Index (DXY) has experienced three bull market traps (2017/2020/2024), all accompanied by the halving of BTC.D and surges in altcoins. The current dominance rate has fallen from a high of 65%, closely aligning with the trends at the end of 2020.
- Dominance Rate Threshold Broken: The real dominance rate of altcoins, excluding Ethereum and stablecoins, continues to rise. When this metric breaks the historical threshold of 25%, it often triggers a full altcoin season.
- Market Breadth Improvement: With the total market capitalization surpassing $4 trillion, Bitcoin’s share has dropped to 61.4% (the lowest since March), indicating a systematic reallocation of funds towards non-BTC assets.
On-chain analyst Merlijn The Trader pointed out: "The correlation between the US Dollar Index and Bitcoin’s dominance ratio has once again been confirmed, which may be the starting gun for a new altcoin super cycle."
Investment Strategy Outlook
As Bitcoin’s dominance seeks a new balance at 60.95% (key support range 60.0%-60.5%), the market faces two paths:
- If the dominance stabilizes: Bitcoin may gather momentum to challenge the resistance level of $125,000, leading to a gradual rise in the overall market.
- If it continues to break down: It will accelerate the migration of funds towards altcoins, recreating the altcoin season of 2021—when BTC.D plummeted from 90% to 35%, with altcoins averaging over 800% returns.
Currently, it is necessary to closely monitor two key indicators:
- Whether the real dominance rate of altcoins excluding stablecoins can突破 the 25% critical point.
- Whether Ethereum can hold steady at $3,750 and challenge its historical high.
The cryptocurrency market is at a critical turning point: while Bitcoin solidifies its position as a store of value, alternative coin ecosystems are capturing market share at an unprecedented pace. Three factors—improved regulatory frameworks, diversified institutional allocations, and national strategic holdings—are pushing the cryptocurrency market toward a more complex and mature new stage. As capital flows like a tide toward altcoins, a new round of wealth effects may already be brewing beneath the surface.
