To grasp the intricacies of Bitcoin mining, one must first understand what Bitcoin is, distinguished from BTC. Bitcoin comprises two fundamental elements: the Bitcoin blockchain and BTC, the digital asset embedded within this blockchain. There exists only one Bitcoin, but 21 million BTC coins are distributed throughout it. It’s imperative to realize that the Bitcoin blockchain operates similarly to a computer's hard drive, with each block resembling a file. However, unlike conventional hard drives, Bitcoin’s blockchain is distributed across multiple computers, making its operation more decentralized.
