What Are Altcoins? A Beginner’s Guide to Alternative Cryptocurrencies

Altcoin Season Explained: How Digital Assets Beyond BTC Are Evolving

BTC kicked off the digital currency revolution. Since then, thousands of other cryptocurrencies—often called altcoins—have emerged. Each brings its own utility, function, and community.

While BTC is known for being a reliable store of value—often compared to digital gold—many other digital currencies aim to do different things entirely. Some are built to power apps, others to keep prices stable, and some are just… memes that somehow took off.

This article breaks down what altcoins are, how they differ from BTC, and why they're gaining popularity.

What Are Altcoins?

In simple terms, altcoins are any digital assets that aren’t BTC. Some are forks of BTC’s original code with tweaks to how they work. Others are built from scratch with totally different goals.

Many view altcoin networks as two types: BTC forked tokens that enhance its technology and independently created tokens. 

At this point in time, BTC still dominates the crypto space, holding around 59.6% of the total market, according to CoinMarketCap. But altcoins aren’t just background noise—they’re gaining ground fast.

How Altcoins Differ from BTC

BTC’s main purpose is to act as a store of value. Like gold, it's seen as a way to protect wealth and beat inflation. But most altcoins were created with specific use cases in mind.

Let’s break it down with a few examples:

• Ethereum (ETH): Introduced smart contracts, allowing developers to build decentralized apps (DeFi, NFTs, and more).
• Litecoin (LTC): Prioritizes faster transactions.
• Monero (XMR): Focuses on private, anonymous transactions.
• Stablecoins like USDT and USDC: Pegged to the US dollar, aiming for price stability.

Altcoins go beyond just being alternatives to BTC—they power ecosystems.

Why Altcoins Matter During Altcoin Season

Altcoin season typically kicks off after BTC reaches a new peak. As investors take profits from BTC, they often shift into altcoins looking for higher returns. During this period, many altcoins outperform BTC in terms of short-term gains.

To make the most of this time, it’s important to understand the different types of altcoins and what they do.

Types of Altcoins and What They Do

1. Utility Tokens

These tokens give access to services on a specific blockchain. For example, ETH is used to pay gas fees on the Ethereum network. Binance Coin (BNB) started as a way to get trading fee discounts on Binance but now powers a whole ecosystem.

Blockchain users can purchase utility tokens to access specific services or acquire blockchain-based products. Utility tokens differ from BTC because they allow users to access blockchain network features. BTC exists mainly as an alternative currency system.

2. Stablecoins

Stablecoins are designed to offer users a solution to digital currency price volatility. Asset backing reduces price volatility for stablecoins, which can employ fiat currency or gold metals, among other assets. A popular group of stablecoins includes Tether (USDT) and USD Coin (USDC), alongside DAI. 

Stablecoins are a middle ground between crypto and traditional finance since they act as fiat currencies on a crypto network. The market instability of altcoin season requires stablecoins as secure temporary bases that traders can rely on during volatile periods. Traders using wallets like RockWallet depend on stablecoins to secure earnings before returning to the market through new trading opportunities. 

3. Governance Tokens

Users who hold governance tokens receive the power to vote within the blockchain or decentralized application network. Governance tokens empower decentralized communities to participate in voting activities for protocol changes and funding decisions through decentralized decision-making power.

The governance token Maker (MKR) is the primary token that enables the decentralized management of DAI stablecoin at MakerDAO. Users who hold MKR tokens receive voting privileges, meaning they can decide on interest rates and system improvements. Blockchain projects depend on governance tokens as a fundamental component because they give users control over project direction in decentralized environments.

4. Privacy Coins

Privacy coins shield user information while providing maximum anonymity. Darkcoin transactions maintain privacy through strong encryption, preventing users' transaction information from being traced publicly on the blockchain.

XMR, an established privacy-focused cryptocurrency, provides complete privacy through ring signatures and stealth addresses that shield sender and recipient details. Users can utilize Zcash (ZEC) zero-knowledge proof solutions to perform private transactions.

Regulative bodies frequently monitor privacy coins because their anonymizing properties create risks for criminal activities. Society and businesses need financial privacy in the age of expanding digital monitoring.

5. Meme Coins & Niche Tokens

Meme coins typically start as jokes, yet Dogecoin (DOGE) and Shiba Inu (SHIB) obtained widespread recognition after their communities joined forces with social media trends. During altcoin season, prices surge dramatically due to speculation and celebrity support.

Specific industries form the target markets for niche tokens that cover both gaming platforms, decentralized storage solutions, and authentication tools based on artificial intelligence. The blockchain gaming sector uses Axie Infinity (AXS) alongside Filecoin (FIL), which enables decentralized cloud storage. Alternative cryptocurrencies prove the cryptocurrency protocol functions across all fields beyond banking systems.

Altcoins vs. BTC – Key Differences 

The introduction of altcoins offers solutions and functionality that focus on what BTC doesn’t do, making them alternatives to BTC, hence their name. 

Purpose and Functionality

BTC was originally designed to be a form of peer-to-peer electronic cash, but over time, its main role has shifted. Today, it’s primarily seen as a store of value—a kind of digital gold. People hold BTC not so much to spend it, but to protect wealth, hedge against inflation, and preserve long-term value.

Altcoins serve a broader set of requirements than just being the main alternative to BTC. The Ethereum platform enabled developers to access and construct decentralized applications (DApps) through its blockchain technology via its smart contracts system. 

The stability of USDT and USDC, where they are fixed at $1, led to numerous investors using these stablecoins for trading and transactions. Users who need financial privacy use privacy coins like Monero (XMR), which allows anonymous transactions. 

Transaction Speed and Scalability

BTC's main issue concerns its capacity to scale. Investopedia notes that BTC transactions average 10 minutes per block, while Ethereum creates new blocks every few seconds. The deployment of Proof of Stake (PoS) in Ethereum’s network has optimized scalability by lowering network traffic and transaction expenses. 

In terms of other altcoins:

• Litecoin: Thanks to its short block duration, Litecoin network transactions are completed in just 2.5 minutes, according to Cryptomus. 
• Solana (SOL): Cryptomus notes that Solana transactions take only 0.4-0.5 seconds to complete and that up to 65,000 transactions can be processed per second. 
• Avalanche (AVAX): As Kraken noted, transactions take only 1 minute to complete, and 20 confirmations are needed. 

Adoption and Security

BTC remains the most widely adopted digital asset globally. According to Forbes and CoinMarketCap data, as of early March 2025, BTC holds a market cap of approximately $1.77 trillion. Its early launch in 2009 and strong brand recognition gave it a first-mover advantage, leading to widespread acceptance among both retail and institutional investors. Some businesses also accept BTC for payments, adding to its real-world utility.

Altcoins have also seen significant adoption, though on a smaller scale. Ethereum, for example, has grown into the leading smart contract platform, with a market value of around $263.75 billion. It powers a large ecosystem of decentralized applications (dApps), NFTs, and DeFi projects. Binance Coin (BNB), valued at roughly $87.79 billion, is heavily used on the Binance exchange and its associated blockchain, BNB Smart Chain.

These numbers reflect how altcoins are carving out distinct roles and gaining traction beyond BTC—expanding the reach and diversity of digital asset adoption.

Final Thoughts

Altcoins have reshaped the crypto world. They bring innovation, serve new markets, and unlock features BTC wasn’t designed for. Together, BTC and altcoins form a diverse ecosystem with opportunities for every kind of investor.

As more people look beyond BTC, altcoins are becoming harder to ignore. They’re not just alternatives—they’re essential parts of the next evolution in digital finance.

Whether you’re in it for the tech, the gains, or the vision, understanding altcoins is key to navigating the crypto market today.
