Altcoins (short for "alternative coins") refer to all cryptocurrencies other than Bitcoin. The Chinese term "山寨币" (shān zhài bì) originated because early cryptocurrencies were often forks (copies) of Bitcoin's code. However, as blockchain technology evolves, many projects now feature unique ecosystems and innovations, making "altcoin" increasingly replaced by terms like "major cryptocurrencies."
