NFT Beginner's Complete Guide to Non-Fungible Tokens

What Is an NFT?

NFT stands for non-fungible token.

An NFT is a digital token recorded on a blockchain. It can represent an on-chain certificate for a unique digital item or real-world asset, such as digital art, an in-game item, music, membership, an event ticket, or a Web3 domain.

“Non-fungible” means each token can have a distinct identifier, attributes, and content. Unlike ordinary currency, one NFT cannot necessarily be replaced by another identical unit.

For example, two banknotes of the same denomination generally have the same payment value and are interchangeable. Two paintings of the same size, however, may have entirely different values because of their creators, histories, and scarcity.

NFTs bring this kind of uniqueness onto a blockchain.

According to Ethereum.org's introduction to NFTs, NFTs can represent unique Ethereum assets whose ownership can be publicly verified through the blockchain.

An NFT records ownership of a token and related information. It does not necessarily mean the associated image, music, or other file is stored entirely on-chain, nor does it automatically give the buyer copyright in the work.

How Are NFTs Different from Regular Cryptocurrencies?

Bitcoin, Ether, and stablecoins are generally fungible assets.

Each unit of a fungible asset performs the same function under the same conditions. For example, 1 ETH in one wallet can be exchanged for 1 ETH in another wallet.

An NFT has its own identifier and attributes. Even two NFTs from the same collection may have different values because of their appearance, rare traits, history, or utility.

The main differences between NFTs and ordinary cryptocurrencies are:

1. Units of regular tokens are normally interchangeable, while NFTs usually have distinct identities.

2. Regular tokens are mainly used for payments, trading, governance, or storing value, while NFTs are better suited to representing unique assets.

3. Regular tokens are generally measured by quantity, while NFTs are identified by a specific token number and attributes.

4. A regular token generally has a common market price, while each NFT may have its own price.

5. NFTs are usually less liquid than major cryptocurrencies.

Although an NFT has a unique identifier, uniqueness does not guarantee value. Anyone can create an NFT. Its value also depends on the creator, market demand, utility, community, liquidity, and smart-contract security.

How Do NFTs Work?

NFTs are usually created and managed through smart contracts.

On Ethereum, for example, an NFT smart contract records token identifiers, holder addresses, transfer rules, and a metadata location. When someone buys or receives an NFT, the blockchain updates control of that token to the user's wallet address.

An NFT commonly includes the following information:

1. A smart-contract address identifying the contract to which the NFT belongs.

2. A Token ID distinguishing it from other NFTs in the same contract.

3. An owner address recording the wallet that currently controls it.

4. Metadata describing its name, image, attributes, and other content.

5. Transfer records showing the addresses through which it has moved.

6. Contract rules governing minting, transfers, burning, and permissions.

An NFT's image or video may be stored directly on-chain, on IPFS or another distributed storage network, or on an ordinary server.

To judge whether an NFT can remain accessible over time, do not look only at whether the token exists. Check where its image and metadata are stored, whether they can be changed, and whether they will remain available if a related service closes.

What Are ERC-721 and ERC-1155?

ERC-721 is one of the most widely used NFT standards on Ethereum.

The ERC-721 standard defines basic interfaces for tracking and transferring non-fungible tokens. Each NFT is identified by a distinct Token ID, making the standard suitable for digital art, collectibles, and unique game characters.

ERC-1155 is a multi-token standard. One smart contract can manage multiple fungible and non-fungible asset types.

For example, a blockchain game could use one ERC-1155 contract to manage limited-edition weapons, common materials, consumables, and character skins. Some assets may have a supply of one, while others may have multiple copies.

When viewing an NFT, confirm its contract address and token standard. Do not judge authenticity from the image or collection name alone. The same image can be uploaded repeatedly, but the official contract address is usually essential for identifying an NFT's origin.

What Is the Core Value of an NFT?

5.1 Verifiable Digital Ownership

An NFT can associate a digital asset with a particular blockchain address. Anyone can use a blockchain explorer to check the current holder and the token's transfer history.

This public verification reduces reliance on a single platform's internal database.

More precisely, NFT ownership means control of an on-chain token. It should not be interpreted as automatically granting every right to the associated image, brand, or intellectual property.

5.2 Digital Scarcity

An NFT smart contract can define supply. A collection may issue only one token or as many as 10,000.

The blockchain can verify how many tokens were minted, but a small supply does not necessarily mean high demand. Meaningful scarcity depends on supply, market demand, and utility together.

5.3 Transferability

NFTs can be moved between compatible wallets and marketplaces. As long as the underlying network, smart contract, and asset files remain available, users generally do not have to rely on the platform where they first acquired the NFT.

5.4 Composability

Developers can connect NFTs to different Web3 applications.

One NFT may serve as a game character, community membership credential, event ticket, or governance qualification. Cross-application use still depends on whether other applications choose to support that NFT.

5.5 Public Provenance

An NFT's minting, transfers, and transaction history are generally visible on the blockchain, which can help users understand its provenance.

An on-chain record proves only that a particular address performed an action. It does not automatically prove that the minter owned copyright in the original work, nor does it rule out private trades or coordinated activity between related addresses.

For a detailed discussion, see The Core Value of NFTs: Digital Ownership and Scarcity.

What Are the Main Types of NFTs?

6.1 PFP NFTs

PFP stands for profile picture. These NFT collections generally feature people, animals, or fictional characters with different attributes.

Some PFP projects also offer community membership, event access, or brand licensing, but users must check the project's rules to understand the exact rights involved.

6.2 Digital Art NFTs

Artists can turn illustrations, photographs, animations, or generative art into NFTs and issue them through a blockchain.

Buying an art NFT does not necessarily transfer copyright. Buyers should review the project's license and sale terms to determine whether commercial use, modification, or sublicensing is permitted.

The World Intellectual Property Organization notes in its overview of NFTs and copyright that buying an NFT generally does not automatically transfer the underlying work and all rights in it.

6.3 Gaming NFTs

Gaming NFTs can represent characters, equipment, land, pets, or other items.

Unlike traditional in-game items, some gaming NFTs can be transferred to external wallets or markets. Whether they remain usable still depends on the game's operation, servers, smart contracts, and player base.

6.4 Music NFTs

Musicians can issue songs, albums, memorabilia, or membership benefits as NFTs.

Some music NFTs may include listening access, event entry, or revenue-sharing features, but the exact rights must be determined from the project's contract and legal agreement.

6.5 Web3 Domains

Web3 domain systems such as ENS can map a long wallet address to a more recognizable name. The domain itself can also use an NFT to record ownership and transfers.

6.6 Membership and Credential NFTs

NFTs can also represent membership cards, event tickets, course certificates, and community credentials.

The principal value of these NFTs may come from access and real services rather than trading.

For more categories, see NFT Types: PFPs, Art, Gaming, Music, and Domains.

How Are NFTs Created?

The process of creating an NFT is commonly called minting.

Minting uses a smart contract to create a new token on a blockchain and assign it to a specified wallet address.

A typical minting process includes:

1. Prepare an image, music track, video, or other digital content.

2. Choose a blockchain network that supports NFTs.

3. Prepare a compatible wallet and enough funds for network fees.

4. Select an NFT creation tool or deploy a smart contract.

5. Set the name, description, attributes, and supply.

6. Confirm how the file and metadata will be stored.

7. Review contract permissions, royalties, and transfer rules.

8. Sign with the wallet and submit the minting transaction.

9. Wait for blockchain confirmation.

10. Check the contract address and Token ID.

Creators should mint only content they own or are authorized to use. Turning someone else's image, music, or brand material into an NFT may create copyright, trademark, or other legal risks.

For a first mint, see How to Mint Your First NFT.

How Do You Buy and Sell NFTs?

NFTs are generally traded through dedicated NFT marketplaces. OpenSea and Blur are examples, but supported networks, fees, and trading rules may change. Always review the latest platform information before acting.

A typical NFT purchase works as follows:

1. Set up a compatible wallet through an official channel.

2. Confirm the blockchain network on which the NFT exists.

3. Prepare the purchase asset and the network's native token for Gas.

4. Connect the wallet through the marketplace's official website.

5. Find the project and verify its official contract address.

6. Review its price, holders, attributes, and transaction history.

7. Choose to buy immediately or submit an offer.

8. Check the amount, asset, and permissions in the wallet prompt.

9. Sign and wait for transaction confirmation.

10. Verify the NFT in the wallet or a blockchain explorer.

To sell an NFT, users typically open their asset page, choose the NFT, and set a price or accept an existing offer. According to OpenSea's official guidance, NFTs can be traded by creating listings or accepting offers.

Users should also confirm platform fees, creator earnings, Gas costs, offer currency, and order expiration.

For detailed steps, see How to Buy and Sell NFTs: OpenSea and Blur Tutorial.

What Is a Blue-Chip NFT?

“Blue-chip NFT” is an informal market label for certain well-known projects with longer histories and relatively active trading.

CryptoPunks and Bored Ape Yacht Club, or BAYC, are frequently discussed examples of PFP projects.

The market commonly evaluates an NFT collection using:

1. The project's history and creation date.

2. The creator's or team's background.

3. Contract authenticity and security.

4. The number and concentration of holders.

5. Trading activity and bid-ask spreads.

6. Community participation.

7. Brand influence.

8. The NFT's actual benefits.

9. How images and metadata are stored.

10. Whether the team retains authority to change the contract or issue more assets.

“Blue chip” is only a market label. It does not guarantee that an NFT will retain value or generate returns. Even prominent projects may experience price declines, reduced liquidity, and lower community activity.

For examples, see CryptoPunks and BAYC: The Value Drivers of Blue-Chip NFTs.

Are There NFTs on Bitcoin?

NFTs initially developed mainly on smart-contract networks such as Ethereum, but the Bitcoin ecosystem now includes Ordinals and inscriptions.

Ordinal theory provides a method for ordering and tracking satoshis, the smallest unit of Bitcoin. Users can inscribe images, text, or other content onto particular satoshis to create Bitcoin-native digital collectibles.

According to the Ordinal Theory Handbook, inscription content can be included in a Bitcoin transaction and held or transferred through Bitcoin addresses and UTXOs.

BRC-20 is an experimental fungible-token mechanism based on inscriptions. It is related to the Ordinals ecosystem, but BRC-20 tokens are not NFTs in the traditional sense.

Users handling Bitcoin inscriptions need wallets that support Ordinals and can identify inscriptions. An ordinary Bitcoin transfer that does not control UTXOs correctly may accidentally send an inscription as a normal satoshi or spend it as a miner fee.

For more, see Bitcoin NFTs: The Ordinals and BRC-20 Inscription Ecosystem.

How Can You Assess an NFT's Value?

There is no universal NFT valuation model. Beginners should not judge an NFT only by how attractive its image is or by its previous all-time-high price.

Consider the following factors:

11.1 Contract Authenticity

Confirm that the NFT contract address matches the information published by the project's official website and social accounts. An identical name and image do not prove that two assets belong to the same collection.

11.2 Supply

Review the total supply, amount already minted, team allocation, and whether more tokens can be issued.

11.3 Holder Distribution

If a large share of the collection is concentrated in a few wallets, sales by major holders may have a substantial effect on market prices.

11.4 Trading Activity

Volume, active buyers, order-book depth, and bid-ask spreads can help indicate liquidity.

The floor price is only the current lowest listing. It does not mean a buyer is willing to pay that amount.

11.5 Rare Traits

NFTs in the same collection may be priced differently because of backgrounds, clothing, colors, or special traits.

Rarity is only one valuation factor. If the collection lacks overall demand, even an NFT with rare traits may be difficult to sell.

11.6 Utility

Some NFTs provide game functions, membership, event tickets, or access to content. Users should confirm that these features are already available instead of relying solely on future promises.

11.7 Team and Permissions

Check whether the team is public, whether the smart contract has been audited, and whether administrators can pause trading, change metadata, or adjust supply.

For a complete framework, see NFT Market Analysis: How to Assess an NFT's Investment Value.

How Do NFTs Affect the Creator Economy?

Traditional digital content often relies on platforms for publishing, discovery, and payments. The income creators receive therefore tends to depend on platform rules.

NFTs allow creators to issue digital works directly and receive sale proceeds through wallets. Smart contracts can also record royalty recipients and calculation methods.

ERC-2981 provides a standardized way to retrieve NFT royalty information. However, the ERC-2981 standard mainly communicates the royalty recipient and amount to a marketplace; it cannot guarantee that every market or transfer will pay a royalty automatically.

Royalty enforcement depends on the NFT contract, marketplace rules, and transaction method. Creators should not assume every secondary sale will produce income.

NFTs can also support models such as:

1. Limited-edition digital works.

2. Membership NFTs and paid communities.

3. Music or video collectibles.

4. Online and offline event tickets.

5. Game characters and co-branded assets.

6. Collector-only content.

7. Collaborative community creation.

8. On-chain identity and contribution credentials.

What Are the Risks of NFTs?

13.1 Price Volatility

NFT prices can rise or fall sharply over a short period. Past sale prices, floor prices, and listing prices do not guarantee that a future buyer will appear.

13.2 Liquidity Risk

NFTs cannot usually be divided and sold as quickly as major cryptocurrencies at a common market price. Some NFTs may have no buyers for a long time.

13.3 Impersonated Projects

Scammers may copy the name, images, and website of a well-known project. Verify the official contract address before buying instead of relying on the avatar or collection name.

13.4 Phishing and Malicious Approvals

Fake NFT sites may induce users to sign malicious transactions. A single unsafe approval can affect multiple assets in a wallet.

13.5 Smart-Contract Risk

Contract vulnerabilities or administrator permissions may prevent an NFT from being transferred, allow unexpected minting, or cause it to lose its original function.

13.6 Metadata Risk

If an image and its metadata depend on one server, the token may continue to exist after the server closes while its image no longer displays.

13.7 Copyright Risk

Anyone can attempt to turn a digital file into an NFT, but doing so does not prove that the minter owns copyright. Buyers may acquire unauthorized content.

13.8 Market Manipulation Risk

Some transaction records may come from trades between related wallets. High sale prices and volume do not necessarily reflect genuine market demand.

13.9 Network Fee Risk

Minting, buying, selling, and transferring an NFT may require Gas. Fees can increase significantly during network congestion, and a failed transaction may still incur a cost.

NFT Safety Tips for Beginners

When using NFTs for the first time, consider these principles:

1. Enter websites only through a project's official channels.

2. Verify the smart-contract address and blockchain network.

3. Do not connect a wallet through a link received in a private message.

4. Use a small amount for the first transaction.

5. Prepare a separate wallet for NFT activity.

6. Never disclose a private key or recovery phrase.

7. Confirm the transaction details and approval scope before signing.

8. Do not treat a floor price as a price at which you can sell immediately.

9. Do not buy impulsively because of rare traits or celebrity promotion.

10. Confirm whether the NFT includes commercial-use rights or other benefits.

11. Review how the metadata and image are stored.

12. Consider a hardware wallet or multisignature arrangement for high-value NFTs.

13. Revoke contract approvals that are no longer needed.

14. Do not treat NFTs as investments with guaranteed returns.

How Can You Explore NFTs and Web3 Through Hotcoin?

NFTs are usually received, viewed, and transferred through Web3 wallets.

Users can visit the Hotcoin Web3 Wallet to learn about on-chain wallets and related Web3 functions, or download the Hotcoin App to explore the platform's services.

Before using a wallet, confirm:

1. The blockchain network currently selected.

2. Whether the wallet supports the relevant NFT standard.

3. Whether the NFT contract address is correct.

4. Whether the network's native token is needed for Gas.

5. The exact permissions requested by a wallet signature.

6. How the wallet can be recovered if the device is lost.

Users can also review the Ether market page and Bitcoin market page for market information about assets related to these networks.

NFT FAQ

16.1 Is an NFT Just a Picture?

No. An NFT is a token record on a blockchain. An image, music track, or video is usually content associated with the NFT and may be stored on-chain, on a distributed storage network, or on an ordinary server.

16.2 Do You Receive Copyright When You Buy an NFT?

Not necessarily. Buying an NFT generally means acquiring the corresponding token. Rights to copy, modify, or commercially use the work depend on the project's license and sale agreement.

16.3 Can an NFT Be Copied?

An image associated with an NFT can be copied, but the on-chain record tied to a particular contract address and Token ID cannot be directly replaced by another identical token. On-chain uniqueness does not mean the associated image cannot be imitated.

16.4 Are NFTs Always Scarce?

An NFT can have a limited supply, but anyone may create a new collection. Limited supply is a technical property and does not by itself demonstrate market value.

16.5 Can NFTs Be Used Across Platforms?

Some NFTs can be recognized by multiple compatible wallets and markets. Whether they can be used in different games or applications depends on whether those applications choose to integrate them.

16.6 Can an NFT Transaction Be Reversed?

A transfer confirmed on a blockchain is generally difficult to reverse. Check the address, network, asset, and transaction details before sending.

16.7 Do All NFTs Generate Royalties?

No. Royalties depend on contract design, marketplace support, and transaction method. Even when an NFT exposes royalty information, not every marketplace is required to enforce it.

Summary

An NFT is a blockchain token used to represent a unique digital asset. It can record a token identifier, holder address, attributes, and transfer history, and it can be used for digital art, PFPs, game items, music, Web3 domains, and membership credentials.

NFTs provide verifiable digital ownership, scarcity, and asset transfer capabilities. They also give creators new ways to issue works and build communities.

NFTs do not inherently have value, however, and they do not automatically transfer copyright. Price volatility, weak liquidity, impersonated projects, malicious approvals, contract vulnerabilities, and unavailable metadata can all cause losses.

Before buying or minting an NFT, beginners should verify the official contract address, understand storage and asset rights, and use a small amount for their first transaction.
