Against the backdrop of the overall decline in attention to the cryptocurrency market, an abnormal phenomenon is emerging: altcoins are not continuing to crash. Currently, the trading volume of altcoins has fallen to multi-year lows. Market sentiment appears similar to the deep correction phases of 2019 and 2022, but structural differences are beginning to emerge. Data shows that in December, the spot trading activity of major altcoins has significantly slowed down. XRP trading volume dropped to about $32 billion, the lowest since 2025, with nearly half coming from the BNB ecosystem. BNB trading volume is approximately $13.7 billion, also at a yearly low. Solana (SOL), traditionally regarded as a high-activity representative, has seen its market cap fall to about $43 billion, hitting a new low since 2024. Cardano (ADA) has a market cap of around $38 billion, indicating a general weakening of mainstream altcoin attention.
