Differences Between NFTs and Cryptocurrencies

NFTs (Non-Fungible Tokens) and cryptocurrencies are both digital assets that operate on blockchain networks, but they differ significantly in terms of functionality and characteristics:


Cryptocurrencies like Bitcoin and Ether are fungible, meaning each unit is interchangeable with any other unit of the same type and has the same value. For example, one Bitcoin is equal in value to any other Bitcoin and can be freely exchanged. This fungibility makes cryptocurrencies suitable for use as a medium of exchange and a store of value.

On the other hand, NFTs (Non-Fungible Tokens) are unique digital assets that cannot be exchanged on a one-to-one basis with another NFT due to their distinct attributes. Each NFT represents a specific digital item or asset, such as digital art, music, or collectibles, and has unique characteristics that set it apart from other tokens. Because of their non-fungible nature, NFTs are suitable for representing ownership and authenticity of unique assets in a digital format.


Cryptocurrencies primarily act as digital money. They function as a store of value, like traditional currency, and can also be used as a medium of exchange. Examples include Bitcoin and Ethereum, which are designed to be interchangeable (fungible), making them suitable for everyday transactions.

On the other hand, NFTs serve as digital certificates that verify the ownership and authenticity of unique items. These items include digital art, music, virtual goods, and even real estate. By providing proof of ownership on the blockchain, NFTs facilitate the buying, selling, and trading of unique digital assets. Unlike cryptocurrencies, NFTs are non-fungible, meaning each token is unique and not directly interchangeable with another. This characteristic allows NFTs to represent one-of-a-kind digital or physical assets, ensuring they retain their distinct value.


Cryptocurrencies typically adhere to a standard or protocol associated with a particular blockchain. For instance, Bitcoin operates on its own protocol designed specifically for the Bitcoin blockchain, whereas Ethereum uses the ERC-20 standard. ERC-20 is a widely adopted protocol that ensures fungible tokens can be exchanged seamlessly on the Ethereum network, providing a standard format for developers.

In contrast, NFTs follow unique standards like Ethereum’s ERC-721 and ERC-1155, which are specifically created to represent unique items. The ERC-721 standard is the original framework for NFTs, where each token is uniquely identifiable and indivisible, suitable for one-of-a-kind assets like digital art or collectibles. The ERC-1155 standard expands on this by allowing multiple types of tokens (both fungible and non-fungible) to exist within a single smart contract. This versatility makes it ideal for applications like gaming, where a mix of unique and interchangeable assets is necessary.

Use Cases:

Cryptocurrencies are digital currencies that function primarily as mediums of exchange, investment vehicles, and tools for financial transactions. They facilitate online purchases, remittances, and payments through decentralized finance (DeFi) platforms. For instance, cryptocurrencies like Bitcoin are commonly used for direct purchases, while Ethereum serves as a foundational currency for many DeFi protocols, enabling peer-to-peer lending, borrowing, and trading.

NFTs, in contrast, represent unique digital items across various creative domains. They are widely used in digital art, where artists can sell their works directly to buyers without intermediaries. In gaming, NFTs can represent in-game items that players can buy, sell, or trade. Music artists use NFTs to offer exclusive content, and virtual real estate allows for the ownership and trading of digital properties within virtual worlds. These diverse applications highlight NFTs’ role in verifying ownership, creating scarcity, and building digital economies around unique digital assets.

Trading and Storage:

Cryptocurrencies are digital currencies like Bitcoin and Ethereum that can be stored in digital wallets, which are software or hardware tools used to securely manage crypto assets. These wallets enable users to send, receive, and store their cryptocurrencies. They also interact with crypto exchanges, where users can trade various cryptocurrencies or convert them into traditional currencies.

NFTs are also stored in digital wallets, but since they represent unique digital assets, they are typically bought and sold on specialized NFT marketplaces like OpenSea or Rarible. These platforms are tailored specifically to handle the sale and transfer of NFTs, providing features that allow users to browse, bid, auction, and verify ownership. Both cryptocurrencies and NFTs rely on digital wallets for safe storage, and the blockchain ensures secure ownership records. However, the marketplaces differ in their approach due to the unique nature of NFTs versus the fungible nature of cryptocurrencies.


Cryptocurrencies often have a finite supply, meaning there’s a maximum limit on the total number of coins that can ever exist. For example, Bitcoin is capped at 21 million coins. This scarcity is embedded into the protocol to create a deflationary economic model, which some investors believe increases its value over time.

In contrast, NFTs are non-fungible tokens that are inherently unique, meaning each token has specific attributes that distinguish it from others. The supply of an NFT is determined by its creator and is often limited to a single, unique instance or a specific series. For example, a digital artist might create a one-of-a-kind artwork or release a limited series of 10. This limited supply adds to the value of NFTs by creating rarity and exclusivity, similar to how limited-edition art or collectibles work in the physical world.

The differences between cryptocurrencies and NFTs emphasize the distinctive characteristics of NFTs compared to the standardized nature of cryptocurrencies. Cryptocurrencies, like Bitcoin or Ethereum, are fungible, meaning each unit is interchangeable with another and holds the same value. This uniformity allows them to serve as digital currencies that can be easily traded and used for transactions.

In contrast, NFTs are non-fungible, meaning each token represents a unique digital asset with specific properties that differentiate it from others. This uniqueness makes NFTs ideal for representing ownership and authenticity of digital or physical items like art, music, and virtual real estate. The metadata associated with each NFT provides detailed information about the asset, including a link to its digital file.

Furthermore, cryptocurrencies often have a finite supply embedded into their protocols, creating scarcity that can affect their value. Bitcoin, for instance, is capped at 21 million coins. NFTs, on the other hand, can have variable supply based on the creator’s intent, with each series or collection often designed for rarity and exclusivity.

These key differences underscore NFTs as unique digital assets distinct from the fungible, interchangeable nature of cryptocurrencies, providing new ways to own, buy, sell, and trade digital and creative assets.
