Bitcoin's market dominance is slippingand that could be the signal altcoin investors have been waiting for. According to Alphractal CEO Joao Wedson, June 2025 may mark the official start of an altcoin bull market as capital flows out of BTC into alternative assets.
What does Bitcoin dominance mean for altcoins?
BTC dominance measures how much of the total crypto market cap is held in Bitcoin. A falling dominancelike the recent drop from 65% to 62% usually signals that altcoins are gaining traction and outperforming BTC.
Which sectors are seeing the most momentum?
DeFi, Web3 infrastructure, AI tokens, and meme coins are leading the charge. In the past 60 days, 37 out of 57 tracked altcoins have outperformed Bitcoin, according to Wedson's Altcoin Season Index.
Is this the start of a new altseason?
Wedson believes so. He argues that a portion of BTC's $2T market cap will rotate into altcoins, especially those with strong BTC trading pairs like ETH/BTC. His analysis shows many altcoins have bottomed and are poised to climb.
Are all indicators bullish?
Not yet. CoinMarketCap's Altcoin Index still sits at 27. technically indicating it's still Bitcoin season. However, historical trends show that altseason indicators often lag behind actual market behavior.
Conclusion
Altcoin season may be closer than most expect. With BTC dominance shrinking and capital rotating into alts, now might be the time to reevaluate portfolios and position for sector-specific breakouts.
