A fresh analysis from 10x Research shows that altcoins have now maintained an edge over Bitcoin for 31 consecutive days, marking the longest stretch of altcoin dominance in over a year. This comes amid a sharp rebound in global trading flows and Ethereum’s rally toward price levels last seen in 2021.
10x Research’s tactical altcoin model, which gauges capital rotation between Bitcoin and alternative cryptocurrencies, has favored altcoins since early July. The streak surpasses the November 2024 high of 25 days and the March 2025 peak of 19 days. According to the report, Bitcoin’s market share has steadily slipped while the total crypto market capitalization has climbed, fueling optimism for a more prolonged altcoin cycle.
Ethereum’s breakout is a major driver behind this momentum. The token has rallied toward price levels not seen since late 2021, attracting renewed interest from both retail traders and institutional desks. Meanwhile, South Korea has emerged as a key player in the latest rally, with a weekend trading volume spike exceeding $4 billion — a sudden influx that signals strong speculative demand in Asia.
Geopolitical developments have also played a role. Concerns of a potential clash between U.S. President Donald Trump and Russian President Vladimir Putin initially weighed on markets. However, reports suggest Trump has reached a strategic understanding with the EU by increasing arms sales to Ukraine while signaling a willingness to discuss land concessions in Eastern Europe. This has eased investor concerns and reduced the likelihood of a sudden market pullback.
While similar altcoin rallies in the past year have fizzled quickly, 10x Research suggests the current breakout may prove more sustainable. Broad-based gains across multiple altcoins, combined with strong regional trading spikes and favorable macro shifts, have set a foundation for continued capital rotation away from Bitcoin.
Traders will be closely monitoring Ethereum’s ability to maintain its breakout, Bitcoin’s resilience above key support levels, and whether South Korea’s trading boom spreads to other Asian markets. If these trends persist, the ongoing altcoin run could stretch deep into the fourth quarter, challenging Bitcoin’s dominance in ways not seen since the previous bull market.
