Bitcoin mining

Bitcoin mining is like a giant game of luck. It's a bit like a lottery. People all over the world use their computers to try and guess a special number. That number is called a "hash". If they find the right hash, they get a reward in the form of newly created bitcoins. This is how new bitcoins are created. The process is called mining because the people who do it are like miners looking for gold in the ground. The reward for finding the right hash can be big, but it takes a lot luck and lots of computing power.
