Altcoin

General

Also known as: alt, alternative coin, shitcoin

Any cryptocurrency other than Bitcoin. The term is short for 'alternative coin' and encompasses thousands of projects that launched after Bitcoin, each with varying degrees of technical differentiation.

Overview

The term "altcoin" refers to any cryptocurrency that is not Bitcoin. Since Bitcoin's launch in 2009, thousands of alternative cryptocurrencies have been created, ranging from serious technical experiments to outright scams. The altcoin landscape includes forks of Bitcoin's codebase, entirely new protocols, and tokens built on other platforms.

Categories of Altcoins

Altcoins can be broadly categorized by their relationship to Bitcoin:

  • Bitcoin forks: Projects that copied and modified Bitcoin's code (e.g., Litecoin, Bitcoin Cash). These share much of Bitcoin's architecture but change parameters like block time, supply cap, or consensus mechanism.
  • Independent protocols: Blockchains built from scratch with different architectures and consensus mechanisms.
  • Tokens: Digital assets issued on top of existing blockchains rather than operating their own networks.

The Bitcoin Maximalist Perspective

Many Bitcoiners view altcoins skeptically, arguing that Bitcoin's first-mover advantage, network effects, decentralization, and monetary policy make it uniquely suited as sound money. From this perspective, altcoins dilute focus, introduce unnecessary complexity, and often serve primarily as speculative vehicles rather than solving genuine problems that Bitcoin cannot address.

Common Misconceptions

A frequent misconception is that "diversifying" across multiple cryptocurrencies reduces risk the way diversifying a stock portfolio does. In practice, most altcoins are highly correlated with Bitcoin's price movements while carrying additional risks including smaller development teams, lower liquidity, and centralized governance.
