Bitcoin Mining:
Miners use powerful machines to solve complex math problems. The first one to solve it gets to add the next “block” of transactions to the blockchain and they earn some Bitcoin as a reward.
This process is called “proof of work.” This doesn't mean that Bitcoin is controlled by minners as it requires a lot of energy to keep the systems running and it is a very slow process and need powerfull GPUs.
---> Why it matters?
1. It creates new BTC
2. It verifies transactions
3. It keeps Bitcoin decentralized & secure
Only 21 million Bitcoins will ever exist. So over time, mining rewards get smaller, making BTC more rare.
In short:
Bitcoin mining = solving puzzles to secure the network and earn BTC.
