Bitcoin Dominance fell from 65.8% to 61.82% in July 2025, triggering a surge in altcoin performance.
Past dominance drops, including a 34% decline in 2021, show similar capital rotation patterns in alt seasons.
Ethereum and Ripple gains have significantly contributed to BTC's shrinking market share in recent weeks.
Bitcoin’s dominance in the market has dipped in recent weeks, suggesting a boost in altcoin activity. From early July 2025, BTC.D has fallen from 65.8% to 61.82%, representing a 4.5% drop. This change took place in under three weeks and was driven by strong inflows into alternative digital assets. The recent movement has observed a pattern similar to earlier cycles, indicating fast capital rotation in the crypto market.
A Short-Term Shift Mirrors Previous Market Cycles
According to an observation by Daan Crypto Trades, in the fourth quarter of 2024, BTC.D succumbed by plunging to almost 50% in only a couple of weeks. This action occurred when the market was still volatile and performing well with altcoins.

The level of trading itself was high during that plunge, indicating market players undergoing a ruthless repositioning. By December 2024, Bitcoin Dominance was back up and trended upwards over a period of six months.
Between December 2024 and June 2025, BTC.D ascended back above 65%, a gain of over 15%. This rise overlapped with weakened altcoin views and increased institutional interest in Bitcoin. At that time, market sentiment favored Bitcoin over smaller-cap assets, pushing its supremacy higher.
Recent Decline Fuels Altcoin Outperformance
The current drop of 4.5% in BTC.D has already shown clear effects across altcoin markets. Altcoin-to-Bitcoin pairs have strengthened during this period. This shift indicates a preference for altcoins, with capital flowing out of Bitcoin into higher-risk assets. This trend has caused several altcoins to outperform Bitcoin in recent trading sessions.
Market participants observed a large spike in volume on the day BTC.D reached 61.82%, the lowest level in several months. That spike confirmed growing interest in altcoin positions as Bitcoin loses market share. Although the current decline appears limited, historical patterns reveal how sharp dominance drops can reshape market direction.
Historical Context: Larger Drops Triggered Major Alt Seasons
In early 2021, BTC.D dropped from 74% to 40% in 140 days. That 34% decline marked one of the largest altcoin rallies on record. The move occurred at a time when far fewer altcoins existed, magnifying the impact of capital inflow into a smaller group of assets. At present, even small shifts in dominance affect thousands of tokens across the market.
A shorter-term decline also happened during the post-election rally when BTC.D fell by around 7%. That drop was brief, but it caused a noticeable reaction in altcoin prices before dominance rebounded. Ethereum (ETH) and Ripple (XRP) continue to hold notable shares of the overall crypto market cap.
Their relative outperformance has weighed on BTC.D, especially during the recent slide. As these large-cap assets acquire ground, Bitcoin’s dominance naturally decreases, even if the total market grows. Historically, when markets become overheated or unstable, traders turn capital back into Bitcoin and stablecoins. That conduct often ends short-lived altcoin rallies, as investors seek safety in more liquid assets.
