In 2025, the cryptocurrency market is showing a significant change in bitcoin and altcoin trends. Following bitcoin's significant rise in 2024, many investors expect 2025 to be the year of altcoins, as historically after Bitcoin's halving, its growth has often led to increased interest in alternative cryptocurrencies. Bitcoin's market dominance has reached 61.39%, the highest since March 2021, indicating its strengthening position. However, a decline in Bitcoin's dominance could signal the start of an "alt season" in which altcoins outperform Bitcoin in terms of returns.
