One of the most popular trackers of NFT collections and assets is Rarity.tools
Rarity Tools also publishes custom scores to rank NFTs by how rare those are.
The study
We analyzed 767 Opensea NFT collections added to the Rarity Tools tracker as of January 21st 2022.
Here are the results:
There is almost no correlation between NFT prices and supply.
There is a strong correlation between NFTs supply and number of owners.
There is a correlation between NFTs supply and number of sales.
What it means?
If the number of NFT assets in a collection is large, you will tend to see also many owners of that collections and many sales occurring. However, prices will tend to be small.
NFT collections with fewer issued assets could be more valuable. From those collections, those with higher rarity scores might be even more valuable.
