"Design a 3D icon for a Web3-style virtual currency in the same style as a modern, colorful, and soft-cartoon design. The icon should feature a round coin with smooth, rounded edges and glowing details. Use vibrant colors like purple, blue, and green, with a clean gradient effect. Include subtle lighting and soft shadows to create a polished, modern look. The icon should be simple yet detailed, emphasizing the futuristic and decentralized nature of the virtual currency. No background, just the 3D icon."
