According to online reports, according to data from The Block, Ethereum NFT trading volume rose to US$186 million last week, a three-month high, an increase of 67% from US$111 million in the previous week. The Pudgy Penguins series was the main catalyst driving the boom after its PENGU token issuance. The series generated US$108 million in transaction volume. The trading price of a single Pudgy Penguins once exceeded 29 ETH, but fell rapidly after the token issuance. Bitcoin is the second-largest NFT ecosystem, with a weekly transaction volume of just US$33 million.
