Blue-chip NFTs like Pudgy Penguins and BAYC have recently increased in value, with Pudgy Penguins' floor price rising above 5 ETH, up over 20% in the past week; BAYC's floor price increased 81% over the past 30 days. However, data from CryptoSlam shows that global NFT sales dropped from approximately $304 million in February to about $175 million in April, with both transaction counts and active users decreasing by nearly half. NFT trading activity is now concentrated among a few blue-chip series, with wash trading still accounting for roughly 50% of total trading volume, and some rebounds driven by the rise in ETH and BTC.
