The 7 Main Types of Cryptocurrency

When Bitcoin launched in 2009, it was the only digital currency of its kind. By 2011, though, new types of cryptocurrency began to emerge as competitors adopted the blockchain technology Bitcoin was built on to launch their own platforms and currencies. Suddenly, the race to create more crypto was on.

Read on to learn more about the seven main types of cryptocurrency, from proof-of-work to proof-of-stake cryptocurrencies, to utility tokens, stablecoins, and more.

Understanding the Cryptocurrency Landscape: More Than Just Bitcoin

Bitcoin (BTC) may be the most recognized cryptocurrency, but it is one of thousands. It’s difficult to pin down an exact number for how many cryptocurrencies exist, since new coins continue to be developed while others become obsolete.

By some counts, close to 55 million unique cryptocurrencies have been created over time, with more on the way. While cryptocurrencies have been largely unregulated for much of their history, that’s been changing in recent years. A regulatory framework has begun to take shape as the Securities and Exchange Commission (SEC), U.S. Congress, and other agencies in the U.S. and abroad have passed crypto-related regulations and laws.

What Is Cryptocurrency and Why Do Different Types Exist?

Cryptocurrency is a type of digital asset that’s created, validated, and exchanged through the blockchain, without the need for any type of central clearing intermediary. Transactions are publicly viewable on the blockchain, but the identities of those exchanging cryptocurrencies are not transparent (though not always untraceable), adding to its appeal for some.

Why are there so many different types of cryptocurrency? Innovation, a push towards decentralized finance, and increased market interest all play a part.

Developers have created different types of cryptocurrencies largely to support and expand the capabilities of blockchain networks. Cryptocurrencies such as Bitcoin and Litecoin were developed to support peer-to-peer payments, for example, while others, such as Ethereum and Solana, were designed to support blockchain-based decentralized apps (dApps).

Utility tokens were developed to provide access to services or functionalities on a blockchain network — governance tokens, for instance, allow users to vote on decisions being made by a certain network.

Blockchain technology is also being actively explored in areas outside of finance, such as healthcare, supply chain management, real estate, and art.

The Fundamental Difference: Coins vs Tokens

Although some people use the terms crypto, coins, and tokens interchangeably, they’re not the same. To gain a basic understanding of cryptocurrency, it’s important to understand how these terms differ from one another.

Cryptocurrency may broadly refer to coins or tokens, but the two have different meanings:

•   Coins: Crypto coins are native to their own blockchain network, and provide a means of exchange. They’re strings of computer code that can represent an asset, concept, or project — whether tangible, virtual, or digital — intended for various uses and with varying valuations. Examples include Bitcoin and Ethereum.

•   Tokens: Tokens are programmable assets that are created on an existing blockchain network, and allow users to access certain services or features. They are often distributed via airdrops, staking rewards, and private sales.

While crypto coins operate on their own independent blockchain and offer a broader medium of exchange for that network, tokens are built on top of an existing blockchain and have any number of uses, such as representing an asset — a stake in a precious metal, for example — or facilitating a transaction on the blockchain. Both could potentially be bought or sold through a crypto exchange.

Crypto coins are created, tracked, and verified by their native blockchain network and essentially power the blockchain by serving as payment for the transactions that create and secure new blocks. While crypto coins are fundamentally different from traditional fiat currencies (like the dollar, euro, or yen), they also have some similarities, since both are designed to be a medium of exchange and a unit of value.

Tokens are designed to be used as part of a software application, such as granting access to an app, verifying identity, or tracking products moving through a supply chain. They can represent units of value, too, including for real-world items, like real estate, points, or commodities. They can also represent digital art — as with non-fungible tokens (NFTs). There have even been experiments using NFTs to represent physical assets, such as real-life art and real estate.

Numerous crypto coins and tokens have been introduced at a rapid pace since Bitcoin was launched in 2009, and while this can drive innovation, it’s important to remember that cryptocurrencies come with high risk, as well, such as from scammers counterfeiting tokens or from the high level of volatility these assets experience.

Type 1: Proof of Work (PoW) Cryptocurrencies – The Originals

Proof of work is the original framework Bitcoin was built upon, and it represents the mechanism by which new blocks are added to the blockchain. In a proof of work system, “miners” compete to solve complex mathematical puzzles and earn cryptocurrency.

What Is Proof of Work?

Proof of work is a consensus mechanism, which is a standard that governs how cryptocurrency transactions are validated and information is added to a blockchain network. It allows crypto miners to compete for an opportunity to add a block to the blockchain, and receive a reward for their efforts.

With proof of work, crypto miners use powerful computer systems to race to solve a cryptographic hashing puzzle. The winner creates a new block containing transaction information, which is verified by the network nodes before being added to the chain.

The rewards earned by winning miners are typically a certain number of newly minted coins.

Examples of PoW Coins

Proof of work coins are represented by some of the most well-known types of cryptocurrency. Some of the most popular PoW coins by market cap include:

•   Bitcoin (BTC)

•   Dogecoin (DOGE)

•   Bitcoin Cash (BCH)

•   Litecoin (LTC)

•   Ethereum Classic (ETC)

Bitcoin is the largest PoW coin with a market cap of $1.3 trillion, as of July 2026. There are currently just over 20 million Bitcoins in existence, out of a maximum hard cap of 21 million. The last Bitcoin is expected to be mined sometime in 2140.

Type 2: Proof of Stake (PoS) Cryptocurrencies – The Evolution

Proof of stake cryptocurrencies were developed as an alternative to proof of work coins, which are viewed as having scalability limitations given the vast amounts of power required to mine them. A proof of stake system relies on crypto staking, rather than mining, but it serves a similar function.

What Is Proof of Stake?

Proof of stake is a consensus mechanism that’s used to reward participants who validate transactions that are added to the blockchain.

Here’s how it works:

•   Stakers agree to lock away some of their cryptocurrency on a blockchain network through a process called staking.

•   The blockchain network can use the holdings to create a new block and validate transactions.

•   The staker with the largest “stake” has a higher probability of being chosen to validate transactions.

•   Validated transactions earn the staker a reward; stakers who violate protocols, however, could face a penalty.

Proof of stake requires much less computing power than proof of work, reducing strain on the energy grid. It allows stakers an opportunity to potentially earn passive income while holding cryptocurrency. However, stakers face the risk that their coins could lose value while they’re locked up for staking.

Examples of PoS Coins

Compared to Bitcoin, proof of stake coins claim a smaller share of the market. However, the numbers are growing, and these coins represent some of the biggest movers in terms of market cap:

•   Ethereum (ETH)

•   Solana (SOL)

•   Cardano (ADA)

•   Toncoin (TON)

•   Algorand (ALGO)

Ethereum has the largest market cap overall of these, at approximately $296 billion as of August 30, 2026.

Type 3: Utility Tokens – The Keys to a Network

Utility tokens, or user tokens, are a type of cryptocurrency that serves a specific purpose inside a decentralized network. They’re built on an existing blockchain and grant their holders access to distinct functions, features, or services.

What Are Utility Tokens?

A utility token is a digital asset that grants holders access to a certain product or service for a given cryptocurrency. They’re typically developed using smart contracts and may be programmed for a range of uses, such as to access storage space or to bring external data onto a blockchain network. Or, as with a governance token, they may give holders the option to vote on changes to a blockchain network.

More broadly, utility tokens can help encourage participation in and support of the crypto ecosystem they were designed for. They may serve as a loyalty bonus, for example, provide access to exclusive features, or other incentives for interacting with the network, all of which may help foster the growth of that crypto community.

Unlike other types of tokens that may confer a stake in an asset or a physical entity, utility tokens serve primarily as a key to various features offered by a cryptocurrency.

Examples of Utility Tokens

Utility tokens are designed with specific use-cases in mind. Their value is typically measured more in terms of what they allow you to do, versus what value they represent.

Here are some examples of utility tokens:

•   Ether (ETH): Ether is the native token of Ethereum, which is the second-largest blockchain network. Ether is used to pay the Ethereum “gas fee” required to process transactions on the blockchain. Given its reach, however, it’s sometimes seen as a currency (having a store of value) in its own right.

•   Chainlink (LINK): Chainlink is a decentralized oracle network that acts as a bridge between smart contracts and real-world data. Tokens are used to pay for data services and incentivize the production of accurate data feeds.

•   Basic Attention Token (BAT): BAT is an Ethereum-based utility token used within the privacy-focused Brave browser ecosystem. Users earn BAT by opting into ads; they can use their tokens to tip content creators, cash out, or unlock premium content and digital rewards.

•   Golem (GLM): Golem is a decentralized supercomputer that lets users rent their computing power to others. Tokens are used to pay for services through the platform.

•   The Sandbox (SAND): SAND is the utility token for the community-driven blockchain gaming platform, The Sandbox. Players can earn SAND and use it to purchase virtual assets, access exclusive interactions, and take part in governance, among other things.

Type 4: Stablecoins – The Price Stability Anchor

Stablecoins are digital assets whose value is tied or “pegged” to another asset, typically the U.S. dollar. Unlike Bitcoin and other cryptocurrencies, which can be highly volatile speculative assets, stablecoins are designed to maintain a relatively stable value, pegging their value to traditional currencies to facilitate digital payments and transfers with less price volatility than many other crypto assets.¹

What Are Stablecoins?

The regulatory landscape for stablecoins is quickly evolving globally, highlighted by the passing of the US. Genius Act in July 2025, which targets payment stablecoin issuers and introduces strong consumer protections.² This parallels the European Union’s Markets in Crypto-Assets (MiCA) regulation, which rolled out its foundational stablecoin rules in 2024.³ Under MiCA, stablecoin issuers face rigid requirements, such as mandating that a significant portion of reserves be held as cash deposits in EU credit institutions rather than solely in U.S. government debt. Consequently, major issuers like Tether (USDT) — which maintains the vast majority of its reserves in U.S. Treasurys — have faced delisting from regulated European platforms due to noncompliance.

As the industry shifts, there are still risks to be aware of, such as a stablecoin losing its peg value, technology or operational risks, or the potential for scams or fraud.

Common uses for stablecoins include:

•   Paying for goods and services

•   Making cross-border payments

•   Offering potential protection against price instability in cryptocurrency markets

Crypto users may use stablecoins to buy other cryptocurrencies in lieu of cash, and more payment processors are allowing the use of these coins to pay for transactions online.

Examples of Stablecoins

Stablecoins represent a growing share of the total cryptocurrency market. Some of the most well-known stablecoins by market cap include:

•   Tether (USDT)

•   USDC (USDC)

•   USDS (USDS)

•   Dai (DAI)

•   PayPal USD (PYUSD)

The total market cap of stablecoins was approximately $309.88 billion as of July 2026. With a few exceptions, stablecoins have a relatively low price point compared to other types of cryptocurrency. For stablecoins, this low price point is by design rather than market dynamics.

Type 5: DeFi Service Providers – The Future of Finance

DeFi service providers represent a subset of the cryptocurrency landscape. They operate on decentralized, blockchain-based frameworks in order to offer services that allow individuals to conduct transactions directly. For example, a DeFi coin is similar to a physical coin in that it transfers value, but it does so without going through a central intermediary.

What Is Decentralized Finance (DeFi)?

Decentralized finance, or DeFi, describes financial services that are executed through the blockchain. By allowing for direct, peer-to-peer transactions, DeFi advocates note that it could help reduce barriers to entry for those who traditionally have a harder time accessing financial services, and allow for potentially faster, cheaper transactions.

Some of the top providers building out the decentralized finance landscape are developing decentralized peer-to-peer exchanges, borrowing and lending protocols, data services through decentralized oracle networks (DONs), and stablecoins, which may help provide a bridge between blockchain systems and traditional assets.

Most, though not all, DeFi protocols and applications are built on Ethereum. DeFi tokens can be used to access services and goods through decentralized apps. Though DeFi tokens represent a smaller share of the cryptocurrency market, their popularity is growing.

DeFi, of course, is in its early stages, and while the blockchain technology itself helps to safeguard information, the other apps, systems, and entities that interact with the network could pose risks. It’s important to be cautious when considering options, especially as crypto regulations continue to develop.

Examples of DeFi Tokens

Here are some of the largest DeFi tokens by market cap:

•   Hyperliquid (HYPE)

•   Decimal (DEL)

•   Chainlink (LINK)

•   Stellar (XLM)

•   Dai (DAI)

As of July 2026, the total DeFi crypto market capitalization sits at approximately $61 billion. It’s essential to distinguish between DeFi tokens and DeFi coins. The difference, again, between tokens and coins is how they relate to the blockchain.

Type 6: Privacy Coins – The Anonymous Transactions

Privacy coins offer anonymity by obscuring certain details about their users. These coins can be sent and received anonymously, without disclosing the location of the parties involved in the transaction.

What Are Privacy Coins?

Privacy coins enable the secure transfer of cryptocurrency without revealing either its origin or destination. This is a key departure from the more public nature of transactions conducted on the blockchain. Public blockchains were designed with the idea that information be transparent and immutable, allowing participants to view and validate the data. With Bitcoin, for example, Bitcoin users can access transaction data (though not identity information) through public Bitcoin addresses used to make payments.

A privacy coin blocks certain information from view through the use of different strategies, including:

•   Protocols that generate stealth addresses

•   Mixing of transactions to make the routing of coins more difficult to trace

•   Tools that allow for the validation of transactions without requiring the disclosure of any identifying information

Privacy coins aren’t accessible in every country or crypto market. Some countries have banned them outright, while others have taken steps to remove some of the secrecy surrounding them.

For example, recent anti-money laundering regulations passed by the European Union will, starting in 2027, ban financial and credit institutions as well as crypto-asset service providers from managing cryptocurrencies that offer anonymous accounts.

Examples of Privacy Coins

The market for privacy coins is smaller than other types of cryptocurrencies, and your ability to buy them may depend on where you live. Examples of popular privacy coins include:

•   Monero (XMR)

•   Zcash (ZEC)

•   Beldex (BDX)

•   Decred (DCR)

•   Dash (DASH)

As of July 2027, the privacy coin market is valued at approximately $15 billion. A glance at pricing charts shows that privacy coins have the potential to be exceptionally volatile.

Type 7: Meme Coins – The High Risk, High Reward Speculation

Meme coins are a type of cryptocurrency whose popularity is driven by memes or trends.

What Are Meme Coins?

Meme coins are coins that gain attention because they align with a trend or newsworthy event. Any coin can become a meme coin if someone or something pushes it into the spotlight. Some of the most popular meme coins can develop cult-like followings, which can help drive demand.

Compared to other types of cryptocurrency, meme coins tend to be more volatile because their value is often tied to their popularity. A coin that’s hot today may not be tomorrow, and its value could quickly fizzle if the trend dies down, or the meme that the coin is associated with loses popularity.

Examples of Meme Coins

Meme coins can sometimes be some of the most recognizable cryptocurrencies if they grab the attention of the broader population. Examples of popular meme coins include:

•   Dogecoin (DOGE)

•   Shiba Inu (SHIB)

•   Pepe (PEPE)

•   Pudgy Penguins (PENGU)

•   Bonk (BONK)

Meme coins often have lower prices than other cryptocurrencies. As of July 2026, meme coins had a market cap of $34.7 billion.

The Critical Impact of Tax Treatment

The IRS treats cryptocurrency and other digital assets as property, meaning that any gains you generate from them are taxable. If you have digital asset transactions during the year, you’re required to report them on your tax return.⁴

The sale of digital assets, including cryptocurrency, can trigger capital gains if you sell at a profit, or capital losses if you sell for less than the original purchase price. Selling off crypto assets after seeing huge gains in value could significantly increase your tax liability for the year.

You may be able to offset gains with losses through a process known as tax loss harvesting. That can reduce what you owe in federal taxes for the current year.

Income earned through cryptocurrency activities, such as from mining rewards, is considered ordinary income. Depending on your circumstances, the tax rules applying to your digital assets could get complicated. This is not financial, legal, or tax advice so you may want to talk to a certified public accountant (CPA) or another tax professional about how crypto assets could affect your overall tax picture.

The Takeaway

Cryptocurrencies are digital assets built on distributed ledger networks, generally guided by the principle of decentralization. However, they are not a uniform asset class. They vary by consensus mechanism — such as proof of work and proof of stake — and by functional design, including stablecoins, utility tokens, and decentralized finance (DeFi) governance tokens.

Because different cryptocurrencies serve distinct goals, functionalities, and markets, they carry vastly different risk profiles. Understanding these differences can help you better evaluate how specific digital assets align with your risk tolerance and broader financial goals.

FAQ

How many types of cryptocurrencies are there?

Broadly speaking, cryptocurrencies can be grouped into coins and tokens. Beyond those two main types, there are millions of different types of crypto being exchanged, with new currencies entering the market regularly.

What is the most common type of cryptocurrency?

Bitcoin is the most common and widely recognized cryptocurrency. Launched in 2009 by an anonymous developer or group of developers named Satoshi Nakamoto, it was the first decentralized digital currency. It remains the largest cryptocurrency by market capitalization and serves as the benchmark for the entire digital asset industry.

What is the difference between a coin and a token?

The main difference between a coin and a token is their relationship to the blockchain. Coins are the native digital currency of their blockchain, while tokens sit on top of an existing blockchain. Tokens are often associated with digital currencies, but they can also represent other digital assets, like NFTs, or something intangible, like voting rights.

Are NFTs a type of cryptocurrency?

NFTs or non-fungible tokens are not a type of cryptocurrency, but they share space with crypto on the blockchain. An NFT represents ownership of a unique digital or physical asset, such as a drawing, image, or piece of artwork.
