Royalties give the original owner a percentage of the sale price each time the NFT creation is sold on a marketplace. The average NFT royalty typically ranges from 2-8%.

Ex: I minted 2,000 films with a 4% blockchain royalty. The price for the movies is set at $5 and ready to sell. Each initial sale will yield a majority of the profits (+90%). Every transaction that follows from other sellers will yield the agreed royalty price (4%).
