mining in my opinion is one way to get bitcoin either free or can be paid. the term mining for bitcoin fans is already very popular, even before becoming a way to get bitcoin.
Although miners receive Bitcoin as a reward for the network verification process, mining still incurs operational costs. These include the cost of hardware such as GPU or ASIC miners, significant electricity consumption, and equipment maintenance. Therefore, mining is more accurately considered an activity that requires investment and resources to generate Bitcoin.
