As Bitcoin dominance declines, smart investors recognize the early signs of altcoin season 2025. By monitoring key indicators like the ETH/BTC ratio and volume patterns, you can position yourself before the masses. Remember: altcoin cycles follow a predictable path - Bitcoin leads, large-caps follow, then mid and small-caps surge. The key to success? Strategic portfolio allocation and strict risk management. Don't chase every coin; focus on projects with clear use cases and active development.
