According to Milk Road (@MilkRoadDaily), the dynamics of Altseason in 2021 compared to Altseason in 2025 reflect significant changes in market behavior, liquidity distribution, and trading opportunities across major altcoins and emerging cryptocurrencies. Their analysis highlights that while 2021 Altseason was characterized by rapid price surges in mid-cap and low-cap coins, the 2025 Altseason shows more selective capital flows with a focus on fundamentally strong projects and stricter regulatory oversight (source: Milk Road, Twitter, June 17, 2025). Traders are advised to monitor shifts in sector momentum, on-chain data, and liquidity trends to adapt strategies for the evolving altcoin market. These structural changes could impact the timing and magnitude of returns for assets like ETH, SOL, and other trending altcoins.
