As of today, June 28, 2025, the cryptocurrency landscape is vast and ever-evolving. Determining the exact number of altcoins (alternative cryptocurrencies to Bitcoin) is challenging due to the continuous creation and occasional abandonment of projects.
Current Estimates:
- Early 2023: Over 20,000 cryptocurrencies (UK’s Financial Conduct Authority)
- June 2023: Over 25,000 cryptocurrencies in the marketplace.
- December 2024: More than 16,500 cryptocurrencies were tracked by CoinGecko.
- April 2025: Approximately 17,134 cryptocurrencies exist.
- June 2025: Over 37 million unique cryptocurrencies created, expected to reach 100 million by year-end.
Important Considerations:
- Not all listed cryptocurrencies are actively traded or hold significant value.
- The number of cryptocurrencies is constantly changing.
The altcoin market capitalization (excluding Bitcoin and Ethereum) is $227.333B.

Understanding the Altcoin Landscape
With such a massive number of altcoins available, navigating the market can be daunting. It’s crucial to understand that the vast majority of these projects have little to no real-world utility or lasting value. Many are created as speculative assets or meme coins, while others aim to address specific niches within the blockchain ecosystem.
Categorizing Altcoins
Altcoins can be categorized based on various factors, including:
- Functionality: Some altcoins focus on specific applications like decentralized finance (DeFi), supply chain management, or data storage.
- Consensus Mechanism: Different altcoins employ various consensus mechanisms, such as Proof-of-Stake (PoS), Proof-of-Work (PoW), or Delegated Proof-of-Stake (DPoS).
- Underlying Technology: Some altcoins are forks of existing blockchains, while others are built from scratch with unique architectural designs.
- Market Capitalization: This metric reflects the total value of all coins in circulation and provides a general indication of the project’s popularity and adoption.
Due Diligence is Key
Before investing in any altcoin, thorough research and due diligence are essential. Consider the following factors:
- Team and Development: Evaluate the team’s experience, track record, and commitment to the project.
- Technology and Innovation: Assess the underlying technology, its scalability, security, and potential for real-world adoption.
- Community and Adoption: Analyze the size and engagement of the community, as well as the level of adoption by businesses and users.
- Tokenomics: Understand the token distribution, supply schedule, and potential inflationary or deflationary mechanisms.
- Market Sentiment: Gauge the overall market sentiment towards the altcoin, but be wary of hype and speculation.
The Future of Altcoins
The altcoin market is constantly evolving, with new projects emerging and old ones fading away. While many altcoins will likely fail, some may emerge as leaders in their respective niches, driving innovation and adoption of blockchain technology. Staying informed and conducting thorough research are crucial for navigating this dynamic landscape and making informed investment decisions.
