NFT Key Concepts: Floor Price, Rarity, Royalties, and Minting

Understanding NFT Floor Price

The floor price of an NFT collection is the lowest listed price for any NFT in that collection at a given moment. If the cheapest Bored Ape listed on any marketplace costs 10 ETH, the floor price is 10 ETH. The floor price is the most widely quoted metric for NFT collections because it represents the minimum cost of entry into a collection and serves as a reference point for the entire collection valuation.

Floor price is determined purely by supply and demand: the lowest price a current holder is willing to accept and the willingness of buyers to pay that price. During bull markets, strong buying demand lifts floors rapidly as buyers compete for the limited supply of listed NFTs. During bear markets, holders who need liquidity list below the current floor, pulling the floor price down. Tracking floor price over time provides insight into the health of a collection and the conviction of its holder base.

The floor price is a useful but incomplete metric. It only reflects the price of the cheapest (often least rare or least desirable) NFTs in a collection. Rare or trait-specific NFTs within a collection can trade at significant premiums to floor. A collection with a floor of 1 ETH might have specific rare NFTs trading at 10-50 ETH. The floor tells you the entry cost; it does not tell you the full range of values within the collection.

 

How NFT Rarity Works

Most NFT collections are generated algorithmically by combining multiple trait layers (background, body, eyes, clothing, accessories) with each trait having a different probability of appearing. Common traits appear in many NFTs; rare traits appear in only a small percentage of the collection. An NFT with multiple rare traits is considered a rare NFT and typically commands a significant price premium over common NFTs in the same collection.

Rarity is calculated by combining the individual probabilities of all traits. An NFT with a 1% chance background, a 2% chance accessory, and a 5% chance clothing is rarer than one with a 10% background, a 15% accessory, and a 20% clothing. Various rarity calculation methodologies exist (simple trait count, statistical rarity score, normalised rarity) and different tools may produce different rarity rankings for the same NFT. Rarity Sniper and Rarity Tools are examples of rarity aggregation platforms that calculate and display rarity scores for major collections.

 

Rarity as a Price Driver

Rare NFTs in established collections typically maintain larger price premiums over floor during bear markets than common NFTs, because they appeal to collectors with specific interest in that particular NFT rather than just general collection exposure. However, rare NFTs are also less liquid: there are fewer potential buyers willing to pay a premium for a specific rare piece than for a common floor item. The rarity premium is real but comes with a corresponding liquidity discount.

NFT Royalties

NFT royalties are a percentage of every secondary sale that is automatically sent to the original creator of the NFT collection. When the technology was introduced (pioneered by platforms like Foundation and then Zora), royalties were positioned as a revolutionary mechanism for creators to benefit from the ongoing appreciation of their work: every resale would return a percentage to the artist or developer indefinitely.

Royalties are typically set in the NFT collection smart contract at deployment: a creator might set a 5-10% royalty that flows to their wallet on every secondary transaction. The NFT marketplaces are responsible for reading and enforcing the royalty set in the smart contract, but this enforcement is voluntary at the marketplace level: a marketplace that chooses not to enforce royalties can allow buyers and sellers to transact without the royalty payment, and sellers often prefer this because they net more from the sale.

 

The Royalty Enforcement Debate

The marketplaces that offered optional or zero royalty enforcement (led by Blur in 2022-2023) attracted significant volume because sellers preferred to keep more of the sale proceeds. OpenSea responded by reducing its own platform fees and modifying its royalty enforcement stance. This market-driven shift away from royalty enforcement created a significant debate: creators argued their royalty rights (built into the smart contract) were being bypassed, while marketplace operators argued they were not legally obligated to enforce smart contract royalty terms.

The practical implication for investors is that NFT royalty income is not as reliable or guaranteed as it may initially appear. A project that earns significant secondary sale royalties during a bull market may see that income collapse if the dominant marketplaces for its collection shift to optional royalty enforcement. For collection analysis, checking the royalty structure and the enforcement stance of the marketplace where most volume occurs is important context.

 

What NFT Minting Is

Minting an NFT is the process of creating a new NFT on the blockchain for the first time. When a collection launches, the NFTs do not yet exist on-chain: they are minted by buyers who pay the mint price, which deploys the NFT smart contract data to the blockchain and assigns ownership to the minter. Minting is the primary sale: the collector buys directly from the creator or the collection contract.

Mint events are a critical moment in NFT collection lifecycles. Collections that sell out quickly (within minutes or seconds) signal strong demand and typically see floor prices trade above the mint price immediately after minting. Collections that sell slowly or fail to sell out signal weak demand, and early minters often find themselves holding NFTs worth less than the mint price.

 

Free Mint vs Paid Mint

Free mint collections (where the NFT itself is free, with only gas fees paid) have become popular as a community-building mechanism. Free mints attract large audiences and distribute collection ownership broadly. The tradeoff is that free mints have low barriers to entry, meaning early speculative flipping is common. Paid mints (where a specific mint price is charged) provide projects with upfront revenue for development but filter the buyer base to those with genuine interest or conviction.

 

Allowlists and Public Mints

Many collections use an allowlist (previously called a whitelist) system where certain users are pre-approved to mint at a lower price or before the public sale. Allowlist spots are earned by participating in community activities, engaging on social media, or being early community members. The allowlist stage typically has lower competition and lower costs than the public mint. Public mints that attract high demand can result in significant gas wars, where users bid up gas fees dramatically to ensure their transaction is processed quickly.

 

Evaluating an NFT Collection Before Buying

 

Team and Project Credibility

The team behind an NFT collection determines whether it delivers on its promises. Anonymous teams (common in NFT projects) carry higher rug pull risk: a team with no public identities can abandon the project without reputational consequences. Doxxed teams (with public identities) are accountable and have more to lose from abandonment. Reviewing the team track record, the project roadmap delivery history, and the quality of the community are all important signals. The rug pull identification guide covers the specific warning signs of NFT projects with no genuine intent.

 

Community Strength

NFT collection value is substantially driven by community: a large, engaged, high-conviction community creates organic demand for the collection, generates cultural cachet, and supports floor prices through periods of market weakness. Checking the quality of community engagement (genuine discussion versus bot activity), the longevity of the community, and whether the community is growing or contracting provides insight into the future demand trajectory.

 

Utility and Roadmap Delivery

Some NFT collections are pure art or collectibles with no promised utility; others promise access to events, games, DeFi integrations, or other benefits. Evaluating utility NFTs requires assessing whether the promised utility has been delivered or is realistic to deliver. Comparing what was promised at mint versus what has been delivered months later is a reliable signal of team execution quality.

 

Historical Volume and Holder Distribution

Reviewing the historical trading volume, the number of unique holders, and the percentage of the collection held by the top wallets provides important market structure data. A collection where 80% of the supply is held by 10 wallets is vulnerable to sudden floor price collapses if those holders sell simultaneously. A well-distributed collection with thousands of holders who each own a small number of NFTs is structurally more stable.

 

NFT Tax in Australia

In Australia, NFTs are treated as assets subject to capital gains tax under ATO guidance. Buying an NFT and later selling it at a higher price creates a taxable capital gain. The 50% CGT discount applies for NFTs held longer than 12 months. Buying one NFT with another NFT (swapping one collection for another) is also treated as a taxable disposal event. The ATO NFT tax guide covers the specific treatment, including the rules around NFTs created as part of a business (potentially taxed as income rather than as capital gains).

Gas fees paid to purchase, sell, or mint NFTs may be included in the cost base of the NFT or deductible as transaction costs, depending on the circumstances. Using crypto tax software to track NFT cost bases and disposals is strongly recommended given the complexity of NFT trading histories. The crypto tax record-keeping guide covers the records required for accurate ATO reporting.
