Golden Finance reports that according to The Block, last week the trading volume of Ethereum NFTs rose to $186 million, hitting a three-month high and increasing by 67% compared to the previous week's $111 million. The Pudgy Penguins series was the main catalyst driving this surge after the issuance of its PENGU token, generating a trading volume of $108 million, with the trading price of a single Pudgy Penguin exceeding 29 ETH at one point, but quickly dropping after the token issuance. Bitcoin is the second largest NFT ecosystem, with a weekly trading volume of only $33 million.
