...Initially dismissed as a niche experiment, Bitcoin gained traction as tech enthusiasts recognized its potential to challenge traditional financial systems. Its unique features—decentralization, immutability, and scarcity (with a capped supply of 21 million coins)—laid the foundation for a new asset class. Following Bitcoin’s success, alternative cryptocurrencies, or “altcoins,” began to emerge. Ethereum, launched in 2015, expanded the possibilities of blockchain technology by introducing smart contracts—self-executing contracts that automate agreements without intermediaries. This innovation paved the way for decentralized applications (dApps) and tokenized ecosystems. How Cryptocurrencies Work At the core of every cryptocurrency lies blockc...
