According to Crypto Rover, a significant shift in the crypto market is expected as altcoins are poised for substantial gains while Bitcoin Dominance (BTC.D) is projected to decline, suggesting an upcoming altseason. Traders should monitor altcoin charts closely for breakout signals, as historical trends indicate that falling BTC.D often leads to capital rotation into major and mid-cap altcoins, enhancing opportunities for high-return trades (source: Crypto Rover, Twitter, June 21, 2025). This anticipated move could drive increased volatility and liquidity in the altcoin sector, making portfolio diversification and risk management critical for active crypto traders.
