A vibrant cartoon classroom with bright colours and smooth animation. Alizay, a cheerful girl in a modest colourful outfit, stands at the front beside a large classroom board, explaining Bitcoin to Rayyan and Ali. Rayyan and Ali, two curious boys in colourful casual clothes, sit at their desks looking intrigued. On the board is a simple glowing illustration of a digital Bitcoin symbol connected by lines to a smartphone and a digital wallet, clearly showing that Bitcoin is digital rather than a physical coin. Rayyan leans forward with a surprised expression while Ali points curiously toward the board. Alizay gestures toward the digital illustration as she teaches. Keep the scene friendly, educational, lively, and child-focused, with expressive facial reactions and gentle character movement. Alizay says: "Bitcoin is a digital currency-it isn't a physical coin."
