Introduction to Dominant Cryptocurrencies
Bitcoin (BTC)
As the pioneer of cryptocurrencies, Bitcoin was introduced in 2009 by the pseudonymous Satoshi Nakamoto. Initially deemed worthless, its value skyrocketed over the years—famously exemplified by the 2010 pizza purchase worth 10,000 BTC (valued at over $300 million today).
Key Features:
- Market leader with the highest capitalization.
- Widely recognized but faces challenges like network congestion and high transaction fees.
Bitcoin's dominance spurred the creation of alternative coins like Ethereum and Bitcoin Cash.
Bitcoin Cash (BCH)
Born from a hard fork of Bitcoin in August 2017 (Block 478,558), Bitcoin Cash emerged to address scalability issues.
Key Differences from BTC:
- Larger block size for faster transactions.
- Holders of BTC during the fork received equivalent BCH.
Litecoin (LTC)
Launched in 2011 as a "lite" version of Bitcoin, Litecoin offers:
- Faster block generation (2.5 minutes vs. Bitcoin’s 10).
- Four times the maximum supply (84 million LTC).
- Scrypt algorithm for mining, incompatible with Bitcoin’s SHA-256.
Ethereum (ETH)
Developed by Vitalik Buterin ("V神") in 2015, Ethereum stands out for:
- Smart contracts: Self-executing agreements on blockchain.
- Low fees and rapid transactions.
- Ongoing innovations like Proof-of-Stake (PoS) and Lightning Network.
Ethereum Classic (ETC)
A result of Ethereum’s 2016 hard fork after the DAO hack, ETC adheres to the original blockchain principles:
- Rejects transaction reversals, maintaining Proof-of-Work (PoW).
- Independent community advocating for decentralization.
Monero (XMR)
Monero (2014) prioritizes privacy:
- Untraceable transactions via advanced cryptography.
- Dynamic block sizes to avoid scalability debates.
- Ensures fungibility—each unit is interchangeable without historical stigma.
