山寨币
Any cryptocurrency other than Bitcoin.
Altcoin is shorthand for “alternative coin” and covers every cryptocurrency that is not Bitcoin, from large-cap assets like Ethereum and Solana down to newly launched micro-cap tokens.
Altcoins usually carry higher volatility than Bitcoin in both directions. They tend to fall harder in downturns and rally faster when capital rotates out of Bitcoin, a pattern traders track through Bitcoin dominance.
