What Are NFTs? Beyond the Hype, the Real Use Cases
An NFT is a tamper-proof certificate of ownership for a unique digital item — recorded permanently on the blockchain.
TL;DR
- NFT = Non-Fungible Token: each one is unique and non-interchangeable, unlike BTC or ETH
- An NFT is a certificate of ownership embedded in a smart contract — not the image itself
- Real use cases beyond art: gaming, event tickets, real estate, diplomas
- The floor price is the cheapest NFT available in a collection — set by sellers, not the project
- Main risks: rug pulls, wash trading, illiquidity, and files stored off-chain
What Is an NFT Technically?
NFT = Non-Fungible Token.
To understand it, you first need to understand fungible:
BTC is fungible: your BTC and my BTC are identical and interchangeable. 1 BTC = 1 BTC, regardless of which one. Like a $50 bill — all $50 bills are equivalent.
An NFT is non-fungible: each token is unique and non-interchangeable. It's a smart contract that proves a specific address owns a specific, unique item on the blockchain.
In short: a digital certificate of ownership written permanently on the blockchain. Tamper-proof, public, permanent.
What You Can Do With an NFT
Forget the $500,000 monkey pictures — that was the most ridiculous and temporary part. NFTs are a technology with real use cases that go far beyond JPEGs.
🎨 Digital Art and Collections
The most well-known case — Bored Apes, CryptoPunks. An artist creates a piece, mints (creates) it as an NFT, and proves authenticity and ownership on the blockchain. The most speculative use case.
🎮 Gaming
Some games let you truly own your in-game items as NFTs. Your sword, your character, your land in a game — it's yours on the blockchain. You can sell it to someone else even if the studio closes down.
🎟️ Tickets and Access
An NFT can be a concert ticket, a community access pass, a subscription. Tamper-proof, transferable, instantly verifiable. No lost paper tickets, no fraud possible.
🏠 Real Estate and Physical Assets
Real properties tokenized as NFTs — ownership recorded on the blockchain. Still emerging, but potentially revolutionary for simplifying property transactions.
🪪 Identity and Credentials
Diplomas, certifications, digital identity. An employer can verify your degree in seconds without calling a university.
How the NFT Market Works
Minting an NFT = creating it on the blockchain. The artist or project deploys a smart contract that generates the NFTs. You pay the gas fee to mint.
Marketplaces
- OpenSea — the largest, on Ethereum and Base
- Blur — for advanced traders, more volume
- Magic Eden — the reference on Solana
The Floor Price
The floor price is the lowest price available to buy in a collection. It's not set by the project — it's automatically the cheapest NFT listed by any of the collection's current owners.
When people say "Bored Apes are at 20 ETH," they mean the floor — the cheapest available, not the average price.
The floor rises when many buyers want an NFT and few sellers are listing. It collapses when everyone lists at once to exit — many sellers, few buyers.
Example: Bored Apes in 2021 — floor at 150 ETH (~$400,000). Bear market 2022–2023 — floor dropped to 15 ETH. Those who bought at the peak lost 90%.
Same mechanics as tokens: supply and demand.
Royalties
Every time an NFT is resold, the original artist automatically receives a percentage via the smart contract. No intermediary, no art gallery. This is a revolution for creators — they keep earning on secondary sales.
Risks and Scams
🪤 Rug Pull
A project launches a collection with a lot of hype, sells all the NFTs — founders disappear with the money. The floor collapses to zero. This is the most common scenario in the NFT world.
🎭 Wash Trading
People buy their own NFTs at inflated prices to simulate activity and make the collection appear popular. Then they sell to real buyers at the peak.
💸 Illiquidity
Unlike ETH which you can always sell, an NFT may be impossible to sell. Even if you paid 5 ETH for it, if nobody wants to buy it, it's worth nothing in practice. An NFT only has value if someone is willing to pay for it.
🖼️ The File Isn't On the Blockchain
Most NFTs only store a link to an image on an external server. If that server disappears → your NFT points to an image that no longer exists. You have the certificate of ownership, but no image.
"Fully on-chain" NFTs (image stored directly in the smart contract) are rare but far more robust — CryptoPunks being a key example.
The question to ask before buying: "Does this NFT have real utility, or am I just buying hoping to sell it for more?" If it's pure speculation — you're playing musical chairs.
