Blockchain infrastructure company BTCS Inc., which is listed on the Nasdaq, has purchased three Pudgy Penguins non-fungible tokens for its corporate treasury. The acquisition expands the firm’s portfolio of digital assets beyond its existing store of more than $300 million in ether (ETH). BTCS said the purchase reflects its strategy of diversifying on-balance-sheet crypto holdings with what it views as established, high-profile NFT collections. Pudgy Penguins is considered one of the earliest so-called ‘blue-chip’ projects in the NFT market, and prices for individual tokens have remained among the highest in the segment since their 2021 launch.
