Cryptocurrencies can be challenging to understand, especially since their underlying technology—blockchain—is often described in highly technical terms. This creates a significant barrier for those eager to learn more about digital assets and how they work.
However, the distinction between different types of cryptocurrencies is crucial for anyone looking to navigate the space effectively. In this guide, we break down the differences between altcoins and tokens, two major categories of digital assets.
What Are Cryptocurrencies?
Cryptocurrencies are digital or virtual currencies that use cryptography for security. This encryption makes them nearly impossible to counterfeit or double-spend. Bitcoin, the first decentralized cryptocurrency, introduced a revolutionary public ledger system known as the blockchain to record and verify all transactions.
Although many digital currencies existed before Bitcoin, its creation marked a turning point due to its decentralized nature. Bitcoin’s success led to the development of a diverse ecosystem of other digital assets, often collectively referred to as cryptocurrencies—even though many don’t function as traditional currencies.
Defining Altcoins and Tokens
It’s important to note that the term "cryptocurrency" is somewhat misleading. A true currency should serve as a unit of account, a store of value, and a medium of exchange. While Bitcoin fulfills these roles, many other digital assets do not.
The cryptocurrency landscape is broadly divided into two categories:
- Alternative cryptocurrency coins (altcoins)
- Tokens
What Are Altcoins?
Altcoins, short for "alternative coins," refer to any cryptocurrency other than Bitcoin. Many altcoins are forks or variations of Bitcoin, created by modifying its open-source code to produce a new coin with different features. This process often involves a hard fork, which fundamentally changes the blockchain’s protocol.
Examples of Bitcoin-based altcoins include Litecoin, Dogecoin, and Namecoin. Other altcoins, like Ethereum, Ripple, and NEO, were built on their own independent blockchains rather than forking from Bitcoin.
A key characteristic of all altcoins is that they operate on their own native blockchains, where all transactions involving the coin are recorded.

What Are Tokens?
Tokens represent assets or utilities and operate on top of an existing blockchain. They can symbolize a wide range of fungible and tradable items, from commodities to loyalty points to other cryptocurrencies.
Creating tokens is simpler than building a new blockchain. Developers use smart contracts—self-executing contracts with terms directly written into code—on platforms like Ethereum or Waves to generate tokens according to standardized templates. These tokens are often distributed through Initial Coin Offerings (ICOs), a crowdfunding method similar to stock IPOs but with key differences.
Tokens benefit from the security and infrastructure of their host blockchain, making them easier to create and manage. The ERC-20 standard on Ethereum, for example, has facilitated the creation of countless tokens.
Key Differences Between Altcoins and Tokens
The primary distinction lies in their underlying infrastructure:
- Altcoins have their own independent blockchains.
- Tokens are built on existing blockchains and rely on them for functionality.
This structural difference means that altcoins generally require more resources and technical expertise to create, while tokens can be developed quickly using established platforms. Approximately 80% of existing digital assets are tokens due to this ease of creation.
Frequently Asked Questions
What is the main difference between an altcoin and a token?
Altcoins operate on their own independent blockchains, while tokens are built on top of existing blockchains and depend on them for transaction processing and security.
Can tokens become altcoins?
Yes, some projects initially launch as tokens on an established blockchain and later develop their own mainnet, effectively becoming altcoins. This process is known as a mainnet swap.
Are all cryptocurrencies except Bitcoin considered altcoins?
Technically, yes. The term "altcoin" refers to any cryptocurrency alternative to Bitcoin. However, tokens are a subset of altcoins that don’t have their own blockchain.
Why are tokens easier to create than altcoins?
Tokens utilize existing blockchain infrastructures and smart contract templates, reducing the need for developing a blockchain from scratch. This simplifies the creation and deployment process.
What are some examples of popular tokens?
Popular tokens include those built on the Ethereum network, such as Chainlink (LINK), Uniswap (UNI), and USD Coin (USDC). These assets rely on Ethereum’s blockchain for their operation.
How do smart contracts facilitate token creation?
Smart contracts automate the creation and management of tokens by encoding rules and functions into programmable code. This eliminates the need for intermediaries and ensures seamless operation on the host blockchain.
Final Thoughts
Understanding the difference between altcoins and tokens is essential for navigating the cryptocurrency landscape. While altcoins function as independent digital currencies with their own blockchains, tokens represent assets or utilities built on existing networks.
This distinction affects everything from development and security to use cases and investment potential. As the crypto ecosystem continues to evolve, recognizing these differences will help you make more informed decisions.
