CRYPTO EXPLAINED (The 'Parent-Friendly' Edition): "Mom, Dad, imagine a giant public notebook that everyone in the world can see, but no one can erase. When I send money to someone, we write it in that notebook. Instead of a bank checking it, thousands of computers around the world all verify that I actually have the money. It's not a physical coin; it's a digital certificate of ownership that's impossible to forge. Think of it like a digital version of gold, but you don't need a safe to keep it in—just a digital key. I'm not gambling; I'm investing in the future of how information and value are moved."
