• Bitcoin’s historical October gains suggest a potential rally toward $138K.
• Altcoins typically consolidate in October before strong November–December surges.
• Market patterns indicate Q4 2025 could be the final low window for large-cap altcoins.

Market sentiment across the crypto space is heating up as historical data aligns with renewed optimism for altcoins. 

VirtualBacon explained that October might be the final opportunity for investors to accumulate large-cap altcoins before another strong market wave.

Over the past decade, Bitcoin has shown a consistent pattern in this month, averaging a 21.6% gain with only one bearish October in ten years. If history repeats, Bitcoin could reach nearly $138,000, fueling liquidity inflows across the broader crypto market.

This seasonal trend has long been a reliable indicator of bullish conditions ahead. Bitcoin’s dominance at the start of every Q4 has often been followed by aggressive capital rotation into altcoins once the leading asset establishes upward momentum.

That rotation typically triggers rallies across mid and low-cap digital assets, creating short but powerful altseasons that define market cycles.

Bitcoin’s New Highs Signal the Next Wave For Altcoins

Bitcoin’s recent breakout to $125,700 has renewed market confidence. Previous breakouts in this cycle, from $73,000 to $107,000 in late 2024, and later to $121,000 by mid-2025, each ignited strong altcoin runs.

This current surge positions Bitcoin in price discovery territory, a phase where its upward trend historically lifts the entire market.

Liquidity spill-over of Bitcoin’s growth normally spills into Ethereum, Solana, and other high-ticket coins, which then trickles down to mid-level and new coins.

VirtualBacon noted that such phases normally start off having Bitcoin dominance rise by approximately 5% during October before tapering off during November and December as altcoins gain traction.

Such movements are indicative of the pivot moment between consolidation and acceleration of coins across the cryptocurrency universe.

The Altseason Setup Strengthens

Such data for past years cements the fact that October is a build-up month for altcoins and not a sell month.

Both for 2023 and 2024, altcoins moved comparatively steadily for October by recording average gains of about 2% before surging a whopping 14% to 36% during the last two months of the year.

Such a trend denotes investors’ apprehensive build-up before risk-on sentiment returns for larger periods to the market.

As Q4 2025 progresses, chart patterns, technical indicators, and cycle studies all point towards a possible end for cheap altcoin positioning in September, before a market turn into a large-scale upside major move.
