Bitcoin is the world\u2019s largest cryptocurrency, but it\u2019s far from the only one. There are thousands of other digital currencies in existence, and they\u2019re known as altcoins. In this guide, we\u2019ll explore the different types of altcoins, how they work, and how they vary from Bitcoin.<\/p>

What is an altcoin?<\/h3>

An altcoin is any cryptocurrency<\/a> that is not Bitcoin.<\/p>

Bitcoin was created in 2009 as the world\u2019s first cryptocurrency. It was intended as a peer-to-peer electronic cash system, but it soon became apparent that Bitcoin had its limitations. Slow transaction speeds, high fees and scalability problems were just some of Bitcoin\u2019s shortcomings.<\/p>

As a result, a range of other alternative coins were developed to improve on Bitcoin and introduce new features. And when you combine the words \u201calternative\u201d and \u201ccoin\u201d, you get altcoin.<\/p>

How many altcoins are there?<\/h3>

A lot. Figures vary between sources, but estimates put the number of cryptocurrencies in existence anywhere between approximately 10,000 and several million. CoinGecko, a cryptocurrency data aggregator, tracks almost 19,000 cryptocurrencies.<\/p>

The vast majority of these altcoins you\u2019ve never heard of, and probably never will. But there are some of these non-Bitcoin cryptos, like Ethereum, Tether and XRP, that have garnered plenty of mainstream media attention.<\/p>

Types of altcoins<\/h3>

Thousands of altcoins have launched since 2011, and most of them can typically be classified into one of the following categories.<\/p>

Payment coins<\/h4>

Like Bitcoin, these coins are designed to be used as a form of peer-to-peer electronic cash. They act as a medium of exchange, and they typically aim to improve on some of the issues that prevent Bitcoin from being used as an alternative payment option to fiat currency.<\/p>

For example, XRP aims to offer fast, low-cost global payments, while Bitcoin Cash offers faster and cheaper transactions than Bitcoin.<\/p>

Stablecoins<\/h4>

A stablecoin is designed to maintain a stable price. Most stablecoins peg their value to a real-world asset like the US dollar, but crypto-backed and algorithmic stablecoins are also available.<\/p>

The purpose of stablecoins is to overcome the infamous volatility of cryptocurrencies which makes them unsuitable for day-to-day use as a store of value and a payment method.<\/p>

Popular stablecoins include Tether and USDC. Learn more in our full guide to stablecoins<\/a>.<\/p>

Utility tokens<\/h4>

A utility token has a specific use within a blockchain network. Rather than being used as a form of payment, it provides access to a specific feature or service within the network. The value of a utility token is based on the demand for the blockchain platform and the features or services the token allows you to access.<\/p>

For example, you may need a utility token to pay network fees, to buy goods or services, to access decentralized apps or to make in-game purchases.<\/p>

ETH is the best-known example of a utility token. It\u2019s used to pay network fees and execute smart contracts on the Ethereum blockchain.<\/p>

Memecoins<\/h4>

Memecoins are typically based on online memes and viral trends. They\u2019re often created as a joke or as a way to reference pop culture.<\/p>

But these less-than-serious coins can sometimes gain serious value. Dogecoin and Shiba Inu are two well-known memecoins that were both created as jokes, but at the time of writing they have market caps of around US$35 billion and US$7 billion respectively.<\/p>

Governance tokens<\/h4>

As the name suggests, holding one of these cryptocurrencies entitles you to have your say in the governance of a blockchain. Holders have voting rights and can help determine things like network upgrades and how funding is allocated. These sorts of tokens help ensure the decentralization of crypto projects.<\/p>

Examples of governance tokens include Hyperliquid\u2019s HYPE token and the Polkadot (DOT) token.<\/p>

Security tokens<\/h4>

When a real-world asset is tokenized and stored on a blockchain, a security token is used to represent ownership of that asset. Common assets that can be represented by security tokens include real estate and shares.<\/p>

Privacy coins<\/h4>

Privacy coins aim to keep crypto transactions private. They include features designed to anonymize transactions and prevent the tracing of transactions.<\/p>

Monero and Zcash are two well-known privacy coins.

Bitcoin dominance and the altcoin season index<\/h3>

When people say that Bitcoin is the world\u2019s largest cryptocurrency, that\u2019s no exaggeration. According to data from CoinGecko, as of October 1, 2025, Bitcoin makes up almost 57% of the total cryptocurrency market cap. This is what\u2019s known as Bitcoin dominance.<\/p>

Bitcoin dominance is a key metric used to measure the performance of cryptocurrencies and the sentiment of crypto traders. In the crypto world at least, Bitcoin is seen as a relatively stable asset, so it becomes a popular safe haven for investors during times of volatility.<\/p>

So when the Bitcoin dominance percentage is high, that\u2019s a sign that BTC is performing better than altcoins.<\/p>

On the flip side, when Bitcoin dominance drops, it indicates that investors are putting their money into altcoins. And when altcoins outperform Bitcoin, it\u2019s known as \u201caltcoin season\u201d or just \u201caltseason\u201d.<\/p>

But how can you tell if it\u2019s altcoin season or not? This is where the Altcoin Season Index comes in. This index tracks the performance of Bitcoin vs the top 50 altcoins by market cap (except for stablecoins and asset-backed tokens) over the past 90 days. If 75% or more of those altcoins have performed better than BTC during that time period, it\u2019s altcoin season.<\/p>

Altcoin season example: 2021<\/h4>

When altcoin season hits, speculation and FOMO are prominent. This means that there is the potential for high price rises among leading altcoins, but you can also expect high volatility and plenty of risk.<\/p>

One famous example of altcoin season occurred during the COVID-19 pandemic in 2021. Driven by factors like the rise of decentralized finance (DeFi), NFTs and low interest rates, Bitcoin\u2019s dominance dropped from 68% to 38%. Altcoins surged, with Ethereum climbing from a price of US$728 in early January to US$4,099 by May 15.<\/p>

10 best altcoins to buy now<\/h3>

There\u2019s no single strategy that can guarantee you will find the best altcoin to invest in. Cryptocurrencies are highly volatile and risky, and there are altcoins out there designed to serve a diverse variety of purposes and real-world use cases. There\u2019s no way of knowing for sure if a particular crypto is worth buying.<\/p>
