Understanding Altcoins
Altcoins (short for "alternative coins") encompass all cryptocurrencies besides Bitcoin. The term originated when early developers modified Bitcoin's open-source code to create new coins with different features or use cases. Though modern altcoins often have distinct technological frameworks, the classification persists.
Key Milestones in Altcoin History:
- 2011: Namecoin (NMC) became the first altcoin.
- 2013-2017: Litecoin (LTC), Ripple (XRP), and Monero (XMR) emerged.
- 2025: Over 12,000 altcoins exist, with Ethereum leading in adoption.
