NFT (non-fungible token) is a mechanism that records proof of ownership for digital data on a blockchain. The point that many beginners often misunderstand is that it does not give you exclusive control over the image or video itself.
This article outlines the basic structure of NFTs, how to think about storing them, and the characteristics of secondary markets, and summarizes the risks to check before buying. Please read it as an introduction to understanding how the system works, not as material for investment decisions.
How NFTs Basically Work
An NFT is a unique token issued on a blockchain, a transaction ledger that is difficult to alter. Cryptoassets such as Bitcoin are fungible: one unit is interchangeable with another of the same type and value. NFTs, by contrast, each carry their own distinct identifying information, so they cannot be swapped one-for-one with another token.
Information about the issuer and owner is recorded on the blockchain, so anyone can verify which wallet holds which token. However, what is typically recorded is mainly "who holds which token." The underlying image or other media file is often stored elsewhere.
Understanding What "Ownership" Really Means
The "ownership" you get with an NFT is mainly proof of ownership tied to a token. It is not the same as making a copy of the original data or acquiring all the copyrights.
In many cases, buyers receive only rights defined by the terms of use, and the copyright may remain with the creator. Before purchasing, it is important to check how the scope of rights is defined in the contract or terms.
Standards and Smart Contracts
NFTs are created according to standards that define the rules for issuing and trading them. In addition, programs called smart contracts are sometimes used to automatically execute transactions.
While smart contracts are convenient, a bug or an exploitable flaw in the program can cause assets to be lost. Because the mechanisms are complex, it is important to check the credibility of the issuer and whether the code has been audited.
Custody Basics: Wallets and Private Keys
NFTs are held in digital wallets. A wallet relies on a private key or recovery phrase, which is used to approve transactions on the blockchain.
If a third party learns your private key or recovery phrase, they may be able to move assets, including NFTs. There are also strengths and weaknesses to both storing assets with an exchange and managing them yourself. Whichever method you choose, you need to understand who bears responsibility for custody.
NFT payments are generally irreversible. If you send funds to the wrong address or approve a transaction on a fraudulent site, the funds cannot be recovered as easily as with a typical online payment, so exercise caution.
Secondary Market and Price Volatility
NFTs are traded on the secondary market, meaning they are bought and sold by people after their initial issuance. When the market is active, prices can sometimes reach high levels, but when demand cools, prices can fall sharply.
For works with low liquidity or collections with few trades, you may not find a buyer when you want to sell. Because prices rise and fall with market demand, it is important not to assume that their value will increase in the future.
Copyright, Counterfeits, and Scam Risks
In the NFT space, there have been cases of people selling other creators' works without permission, and counterfeit listings can be a real problem. Before you buy, check through official information whether the seller is the legitimate issuer.
There have also been reports of scams that pose as distributors of famous works or promise high returns. As a basic rule, do not respond if you receive a direct message on social media or a request to connect from an unfamiliar link.
Things to Check Before You Buy
- Whether the issuer or sales site is official
- The scope of rights you receive with the purchase (terms of use and how copyright is handled)
- The blockchain used for the transaction and the type of wallet you need
- Whether you have confirmed the latest fees and transfer mechanics on official sources
- Whether you understand that prices can fluctuate sharply and whether the amount is one you could lose without hardship
- Whether you have a practice of not clicking on suspicious solicitations or links
Taxes and Regional Differences
The tax treatment of NFT sales and profits varies by country and region, as well as by the nature of the transaction. Tax rules can change, so please check the latest information with official sources such as your national tax authority, or consult a qualified tax professional.
Whether NFT trading is permitted, and which services are available, also differs from one country or region to another. If you want to compare the broader crypto-asset environment, see Cryptocurrency Exchange Comparison. In any case, before choosing any service, you should always confirm its fees and terms using official information.
Summary
NFTs are a mechanism for recording proof of ownership of digital data on a blockchain. They do not give you exclusive control over the data, so it is essential to check copyright and terms of use.
In addition, prices can fluctuate widely, and there are risks such as counterfeits, scams, and payments that are difficult to reverse. Understand how the system works, check official information and your own risk tolerance before buying, and make careful decisions.

Frequently Asked Questions
Does buying an NFT also give me the copyright to the image or video?
