A schematic diagram of data collection and cleaning. First, we selected 198 NFT collections and gathered transfer data from the Ethereum ETL project in Google BigQuery. After collecting transfer data, we grouped rows by buyer (‘To’ columns in the table) and transformed them into purchase trajectories at the NFT level. Then, the purchase trajectories at the NFT level is converted to the trajectories at the collection level after removing duplicated NFT purchases.
