The 2025 market cycle marked a significant divergence from historical trends, with Bitcoin (BTC) closing the year down 6% despite its typical post-halving rallies. Altcoins, represented by TOTAL3 (market cap excluding BTC and ETH), saw their fourth consecutive annual decline against Bitcoin, signaling the end of a fading "altcoin season." Bitcoin's dominance (BTC.D) surged from 40% in 2022 to over 60% in 2025, capturing nearly 80% of the new capital in the crypto market's growth to $1.11 trillion. In contrast, the 2021 cycle was a classic altseason, where TOTAL3 soared 541% compared to BTC's 64% gain. The current altcoin market is plagued by spiked funding rates and overcrowded leveraged longs, making it highly volatile and susceptible to liquidations. With Bitcoin's growing influence and capital funneling into BTC, 2021 likely marked the last true altcoin season.
