I recently started using this NFT portfolio tracker app, and it has been a game changer for my NFT trading on OpenSea. The copy trading approach has assisted me in making better informed decisions about which NFTs to buy and sell and when. I've noticed significant improvement in my total PnL. The basic UI is also very user-friendly, making it simple to follow my portfolio as well as the performance of others. I would strongly suggest this tool to anyone interested in NFT investment or who wants to better manage their existing NFT portfolio.
