We define a rating for artists and collectors in crypto art by focusing on the mutual relationship between them. We start from the intuition that important collectors buy from important artists and important artists sell to important collectors. We hence borrow the Hyperlink-Induced Topic Search (HITS) method, originally developed to detect hubs and authorities on the Web, and adapt it to detect important artists and collectors in crypto art. All data are updated as of April 21, 2021.
