According to data from cryptoslam.io, the top 4 networks in terms of real trading volume in the past 30 days are Bitcoin, Ethereum, Solana, and Polygon. In the last 30 days, the total trading volume of Ethereum NFTs was less than $160 million, while the combined total trading volume of Solana and Polygon, ranked 3rd and 4th, exceeded $148 million, almost approaching Ethereum, which was completely unimaginable in the past. Although the top-ranked Bitcoin NFTs only maintained a slight advantage of over $10 million, starting from March, the monthly real trading volume of Bitcoin NFTs has consistently exceeded that of Ethereum.
