The term Altcoins is used in vastly different ways, with each person seemingly offering their own interpretation. This has sparked numerous debates. At its core, the term refers to "alternative cryptocurrencies," derived from the phrase "Bitcoin alternative." But which definition is correct?
Altcoins Definition – Subtle Yet Important Differences
The term "Altcoin" is a combination of "alternative" and "coin." Depending on one's stance and perspective in the crypto space, the question, "What are Altcoins?" receives varied answers.
Here are three common interpretations:
- Bitcoin Purist View: Bitcoin was the first cryptocurrency. A Bitcoin advocate will label any other cryptocurrency as an Altcoin to emphasize Bitcoin's pioneering role.
- Derivative Coins: Any cryptocurrency built upon or derived from Bitcoin’s codebase qualifies as an Altcoin. Since Bitcoin is open-source, many projects utilize its code for development. However, this definition excludes independently developed cryptocurrencies.
- Functional Parallel: Any cryptocurrency serving the same primary function as Bitcoin (e.g., as a store of value or transactional medium) is considered an Altcoin.
"An Altcoin is a category of cryptocurrencies designed as alternatives to Bitcoin. The term originates from 'Bitcoin alternative.'"

The unifying factor across all definitions? Bitcoin is never an Altcoin. Its first-mover status sets it apart as the benchmark against which Altcoins are measured.
What Role Do Altcoins Serve?
Altcoins, as the name suggests, are alternative coins to Bitcoin. While Bitcoin pioneered decentralized digital currency, it faces challenges like:
- Scalability issues, slowing transaction speeds.
- Energy-intensive mining, raising environmental concerns.
- High transaction fees during peak usage.
Altcoin developers aim to address these limitations, proposing improved solutions.
Another motivator? Financial opportunity. Bitcoin’s success has inspired others to launch competing projects. However, no Altcoin has surpassed Bitcoin’s market capitalization—though during Altcoin Seasons, some outperform Bitcoin in short-term gains.
What Is the Altcoin Season?
An Altcoin Season refers to a period when Altcoins surge in value relative to Bitcoin. Investors monitor Bitcoin dominance—the percentage of total crypto market cap held by Bitcoin. When this metric drops, capital flows into Altcoins.
Bitcoin once dominated ~100% of the market. Today, its share hovers around ~38%, reflecting the rise of innovative Altcoins. Diversifying portfolios during these cycles can yield significant returns.
Examples of Altcoins
Depending on the definition adopted, the list of qualifying Altcoins varies. Below are prominent examples (non-exhaustive):
| Altcoin | Key Feature |
|--------------|-------------------------------------|
| Ethereum | Smart contracts & dApps platform |
| Litecoin | Faster transactions vs. Bitcoin |
| Ripple (XRP)| Bank-friendly payment protocol |
| Cardano | Proof-of-stake scalability |
Why Ethereum Is an Altcoin
Despite Ethereum’s success, it’s classified as an Altcoin because:
- It operates on an independent blockchain with distinct functionalities (e.g., smart contracts).
- Its native asset, Ether (ETH), is a coin (not a token).
- Ethereum wasn’t designed as a pure payment system but as a platform for decentralized applications (dApps).

A: Unlikely. Bitcoin remains the reserve currency of crypto, while Altcoins innovate in niche areas.
Q: How do I identify promising Altcoins?
A: Research use cases, development activity, and community support. Avoid hype-driven projects.
Conclusion
Altcoins embody the crypto ecosystem’s diversity. While definitions vary, their collective innovations drive blockchain technology forward—complementing, not replacing, Bitcoin’s legacy.
