Introduction
Cryptocurrencies have revolutionized the financial landscape, offering decentralized, secure, and innovative solutions for digital transactions. From Bitcoin to altcoins and tokens, the crypto ecosystem is diverse and constantly evolving. This guide explores the top 10 cryptocurrencies by market capitalization, their unique features, underlying technologies, and roles in the digital economy.
Understanding Cryptocurrency Categories
Cryptocurrencies can be broadly classified into two categories:
1. Coins and Altcoins
- Definition: Coins operate on their own independent blockchains. Examples include Bitcoin (BTC) and Ether (ETH).
- Altcoins: Any coin other than Bitcoin, such as Litecoin (LTC) or Dogecoin (DOGE), designed to improve upon Bitcoin's limitations.
2. Tokens
- Definition: Tokens are non-native assets built on existing blockchains (e.g., Ethereum). They include utility tokens (e.g., Chainlink) and stablecoins (e.g., Tether).
- Key Difference: Tokens rely on another blockchain's infrastructure, unlike coins.
