Bitcoin Dominance Falls in 2025: Solana & Altcoins Set to Rally
2025-10-15
Bitcoin’s market dominance has started to decline in October 2025, falling to 58.5% according to CoinMarketCap data, down from a yearly peak of 65.1% in June. This shift is sparking renewed optimism among traders watching for signs of a potential altcoin season.
As Bitcoin consolidates, Solana (SOL), XRP, and other top altcoins are showing signs of renewed strength — signaling what many analysts believe could be the final rotation phase of this bull market.
Market data from TradingView shows the total crypto market capitalization climbing above $3.8 trillion, supported by steady higher lows on the monthly chart.
Analysts warn, however, that the market is approaching resistance levels similar to the late 2017 and early 2021 cycles, suggesting that a breakout or correction could determine the market’s next major direction.
Bitcoin Dominance Breakdown: A Signal for Altcoin Rotation
Bitcoin’s dominance, a key measure of its share in the overall crypto market, now sits at 58.5%, down from its 2025 high of 65.1%. Ethereum follows at 12.9%, while all other altcoins collectively make up 28.6% of the market.
Historically, such declines in Bitcoin dominance have coincided with the start of major altcoin rallies, as capital rotates into riskier, high-reward assets.
Analysts from FXStreet and Ainvest note that Bitcoin’s RSI (Relative Strength Index) is showing early signs of exhaustion.
The RSI divergence pattern from 2021 and 2025 closely resembles previous market tops, indicating that Bitcoin could enter a sideways or corrective phase, allowing altcoins to outperform in the short term.

Solana Leads Altcoin Momentum
Among the top performers, Solana (SOL) continues to stand out. Its ecosystem growth — from DeFi liquidity surges to NFT volume recovery — has positioned it as a key contender for the next leg of the market rally.
SOL has also benefited from its expanding institutional appeal and new listings across Asian and U.S. exchanges.
With Solana’s network achieving record-high daily active addresses, analysts expect it to outperform Ethereum in short-term returns if Bitcoin’s dominance continues to slip below 57%.
This metric is considered a psychological threshold for altcoin season, where capital flows into mid- and low-cap tokens with stronger momentum.

Ripple’s XRPL Attackathon Highlights Developer Activity
Adding to market enthusiasm, Ripple Labs has launched the XRPL Attackathon, a $200,000 bug bounty program focused on its upcoming XRPL lending protocol. The initiative rewards developers for identifying vulnerabilities and strengthening the protocol ahead of its mainnet rollout.
The event signals Ripple’s intent to expand the XRP Ledger (XRPL) beyond payments, venturing into decentralized finance (DeFi).
This development comes as XRP continues to show price stability amid market volatility, potentially attracting more liquidity once the lending platform goes live.
Technical Charts Indicate a Key Turning Point
The total crypto market cap chart shows a rising wedge pattern with multiple rejections near the upper resistance trendline — a formation that previously preceded sharp corrections in 2018 and 2021.
The monthly RSI near 70 reflects a moderately overbought condition, but analysts believe a short-term pullback could pave the way for a broader altcoin breakout by early 2026.

If the RSI repeats its 2021 structure, a brief correction phase could follow, before another push toward $4.5 trillion in total market cap.
This pattern aligns with predictions that Bitcoin may enter consolidation while altcoins like Solana, Avalanche, and Chainlink gain ground.

Conclusion
The gradual decline in Bitcoin dominance and the steady rise in total crypto capitalization suggest that the market is entering a rotational phase. Solana’s strong fundamentals, Ripple’s innovation in DeFi, and Ethereum’s consistent network growth point to a diversified momentum ahead.
While Bitcoin remains the core of the market, the signs are increasingly clear: 2025 could mark the rise of altcoins in the later stages of this bull cycle — provided macro conditions remain stable and liquidity continues to flow into the sector.
