Bitcoin mining is a very difficult process to understand but I will try to simplify it
Bitcoin is a cryptocurrency so unlike our normal paper money which is printed with ink and paper, Bitcoin is mined
So what is mining
mining is the process of figuring out riddles to verify and log transactions. A fresh batch of transactions is added to the blockchain by the first miner to solve these problems in competition. The victorious miner receives more bitcoins as payment. Through this procedure, Bitcoin becomes safe, decentralized, and progressively adds new bitcoins to the network.
This simply means using computer to solve puzzles or riddles using computer and the first miner that wins get Bitcoin as payment
