The crypto market is once again showing signs of a major shift as Bitcoin (BTC) dominance continues to slide, fueling speculation that Altseason 3.0 may be just around the corner. Prominent crypto influencer and investor Shahnawaz took to social media to highlight the cyclical pattern: “2017 → altcoins exploded. 2021 → altcoins surged. 2026 → same pattern forming.” He noted that when Bitcoin falls, money typically flows into altcoins quickly, and the current weakening of BTC dominance suggests the market may be on the cusp of another aggressive altcoin rally.
On-chain and market data support these observations. The Altcoin Season Index, which tracks how many of the top 100 cryptocurrencies by market cap have outperformed Bitcoin over the past 90 days, has risen sharply to 48. This is up from 35 last month and 40 last week, signaling a growing momentum. For context, the index hit an annual high of 78 on September 20, 2025, and a low of 14 on December 19, 2025. Concurrently, Bitcoin dominance (BTC.D) has slipped from 61.2% to 60.6%, another classic indicator of capital rotating into altcoins.
Several altcoins have already posted impressive gains, with ONDO soaring 34.5% to $0.4695, ICP up 32.8% to $3.97, and STRK climbing 21.2% to $0.0558. The Solana and SUI ecosystems, in particular, saw standout performances: JUP rose 18.7%, PYTH 17.5%, SUI 14.7%, and DEEP surged 30.2%. Traders are now closely watching technical resistance levels for Bitcoin, with the $68,000 area cited as a crucial support-turned-resistance. If BTC fails to reclaim that level, analysts believe a swift exodus of capital into altcoins could ignite the next big altseason, repeating the playbook of 2017 and 2021.
