Basics of Altcoins and Investment Decisions Every Cryptocurrency Beginner Should Know

More than 15 years have passed since the advent of Bitcoin, and the cryptocurrency market has undergone dramatic transformation. Currently, there are over 16,500 altcoins in existence, each established as a digital asset with different technological innovations and purposes. While Bitcoin accounts for about half of the total cryptocurrency market value, the remaining half is held by altcoins, and their importance in the crypto ecosystem is growing daily.

What Are Altcoins — All Digital Currencies Except Bitcoin

The term “altcoin” is an abbreviation of “Alternative Coin,” referring to all cryptocurrencies other than Bitcoin. However, some investors and industry experts define altcoins as all cryptocurrencies excluding Bitcoin and Ethereum.

The fundamental goal of altcoin development is to overcome Bitcoin’s limitations. In response to issues such as slow transaction speeds, high energy consumption, lack of privacy features, or insufficient support for specific use cases, numerous projects have adopted different approaches to address these challenges.

Altcoins are generally classified into two categories. One is based on the Bitcoin code with added new features, and the other is built with entirely independent code and operational mechanisms. Each altcoin presents its own value proposition and aims to differentiate itself from other cryptocurrencies.

Risks and Returns of Altcoin Investment

When considering altcoin investments, it is essential to accurately understand their inherent advantages and disadvantages.

Advantages of Investment

High Growth Potential: Altcoins with a much smaller market cap compared to Bitcoin can yield significantly higher profits when successful. A $1,000 investment in a small altcoin could potentially generate greater returns than an equivalent investment in Bitcoin.

Diverse Investment Themes: With thousands of projects available, investors can select projects aligned with specific technological fields, industries, or social issues they wish to address.

Beyond Currency — Functional Utility: Many altcoins are not just stores of value but also provide practical utilities such as supporting decentralized applications (DApps) or granting governance rights.

Disadvantages of Investment

High Risk: Altcoins tend to be more volatile than Bitcoin, with many projects failing and rendering investments worthless. Smaller project sizes amplify these risks.

Extreme Price Volatility: Altcoin markets are highly volatile, with daily price swings of 20–30% not uncommon. This volatility makes timing investment decisions challenging.

Liquidity Constraints: Most altcoins have lower trading volumes than Bitcoin, and large trades can significantly impact prices.

Regulatory Uncertainty: The regulatory environment for cryptocurrencies is still evolving, and future policy changes could severely impact certain categories of altcoins.

Fraud and Failed Projects: The altcoin market hosts numerous scams, unfeasible projects, and Ponzi schemes. The risk of falling for such projects due to insufficient research is high.

Classification of Altcoins — Diverse Use Cases

The current altcoin market is remarkably diverse, with each playing different roles within the crypto ecosystem.

Stablecoins: Digital assets designed to minimize price volatility by pegging their value to stable assets like the US dollar or gold. Examples include USDC, USDT (Tether), and DAI. Unlike typical cryptocurrencies, they aim to maintain stable value and serve as “safe assets” during market volatility.

Utility Tokens: Tokens that provide access to services within specific blockchain networks. They act as digital keys unlocking platform functionalities, such as XRP (for international remittances) and MATIC (Polygon transaction fee payments).

Payment Tokens: Cryptocurrencies designed for value exchange, emphasizing fast processing and low transaction fees for efficient payments.

Governance Tokens: Tokens that grant voting rights in blockchain project decision-making. Similar to corporate shares, Maker (MKR) is a typical example.

Security Tokens: Represent ownership of external assets like stocks or real estate, similar to traditional securities, and are generally subject to securities regulations.

Meme Coins: Cryptocurrencies originating from jokes or internet culture that gained popularity through community support. Dogecoin (DOGE) and Shiba Inu (SHIB) are prime examples of assets that started as memes but gained widespread backing.

Gaming Tokens: Tokens used in blockchain-based games where players earn crypto rewards through gameplay. For example, in Axie Infinity, players breed, raise, and battle fantasy creatures to earn tokens.

Major Altcoins and Their Project Characteristics

In the current altcoin market, the following 10 projects are significant based on market capitalization and utility:

Ethereum (ETH): The largest altcoin, introducing the “smart contract” feature that automatically executes when conditions are met, unlike Bitcoin’s primary function as digital currency. This innovation has enabled thousands of applications across finance, gaming, digital art, and more.

XRP: Developed by Ripple Labs, aiming to enable fast and low-cost international remittances. It is used as an alternative to traditional banking systems, especially for cross-border payments by financial institutions.

Solana (SOL): Known for ultra-fast transaction processing and low costs. The Solana blockchain can process thousands of transactions per second, making it ideal for trading platforms and gaming applications requiring high throughput.

Cardano (ADA): Characterized by a research-driven approach and strong focus on security and sustainability. It employs a proof-of-stake (PoS) consensus mechanism that operates with significantly lower energy consumption than Bitcoin’s mining method.

Litecoin (LTC): One of the earliest altcoins, born in 2011, often called “Bitcoin’s silver.” It offers faster transaction confirmation and uses a different hash algorithm from Bitcoin, maintaining popularity for general payments due to its long track record, low fees, and broad adoption.

Dogecoin (DOGE): Started as a joke based on an internet meme, it has grown into a globally recognized cryptocurrency. Despite its humorous origins, it has a dedicated community and support from celebrities. Its affordability and unlimited supply make it popular for online tips and small transactions.

Tether (USDT): The largest stablecoin by market size, maintaining a 1:1 peg to the US dollar. Each USDT is backed by dollar reserves, facilitating movement between volatile cryptocurrencies and stable assets, and it consistently ranks among the highest in daily trading volume.

USD Coin (USDC): A growing, regulated stablecoin pegged to the US dollar. Issued by the Centre consortium (founded by Circle and Coinbase), it ensures transparency through regular reserve attestations and is a key infrastructure for decentralized finance (DeFi) and cross-border payments.

Shiba Inu (SHIB): Launched in 2020 as a competitor to Dogecoin, rapidly gaining support. Starting as a meme coin, it has expanded into decentralized exchanges (ShibaSwap), NFT platforms, and other utilities. Its low token price allows retail investors to hold millions or billions of tokens, fueling popularity.

Uniswap (UNI): An automated market maker (AMM) that revolutionized crypto trading. As the largest decentralized exchange, it allows users to swap tokens directly from their wallets without intermediaries, and UNI holders participate in governance decisions about the protocol’s future.

Key Indicators of the Altcoin Market — Dominance and Market Cap

For informed decision-making in altcoin investments, understanding two key indicators—altcoin dominance and market capitalization—is essential.

Altcoin Dominance

Altcoin dominance indicates the proportion of the total cryptocurrency market value held by all altcoins. The calculation is as follows:

Altcoin dominance = (Total crypto market cap – Bitcoin market cap) / Total crypto market cap × 100%

When Bitcoin dominance declines, altcoin dominance rises, suggesting increased capital flow into alternative cryptocurrencies. Altcoin dominance charts are powerful tools for market trend analysis.

An increase in dominance (typically over 55%) signals an “altcoin season,” where altcoins outperform Bitcoin.

A decrease in dominance indicates a “Bitcoin-centric market,” where investors favor Bitcoin.

Historically, altcoin dominance peaked around 67% during the 2017–2018 bull run and reached about 60% in mid-2021, coinciding with rapid altcoin market surges.

Market Cap of Altcoins

Altcoin market cap reflects the total value of all circulating altcoins, calculated by multiplying current prices by circulating supplies (excluding Bitcoin).

Insights from monitoring market cap charts include:

• Continuous growth suggests sustained interest in the crypto ecosystem.
• Sharp spikes may indicate excessive speculation or bubbles.
• Comparisons across projects help assess relative importance and adoption levels.

Many investors track the ratio of Bitcoin market cap to total altcoin market cap to capture capital flows. When capital shifts from Bitcoin to altcoins, it often triggers price increases across the altcoin market.

Research Framework for Selecting Altcoins

Given the risks associated with altcoin investments, thorough research before funding is crucial. Key evaluation factors include:

Project’s Core and Problem-Solving Ability

• What real-world problems does the altcoin aim to solve?
