How was Bitcoin mining done in the early days, and what changes have been made to the mining process since then?
Bitcoin mining has evolved significantly since its inception. Initially, miners used CPUs, but as more people began mining, the difficulty level increased. Miners then shifted to GPUs in 2010 due to their improved processing power and efficiency. After that ASICs were introduced, allowing for even more efficient Bitcoin mining. Today, mining Bitcoin requires specialized hardware, software, and access to cheap electricity. Mining pools are also popular, allowing miners to pool resources and increase chances of earning rewards.
