Share Bitcoin mining is the process of earning bitcoin in exchange for running the verification to validate bitcoin transactions.
Miners can profit if the price of bitcoins exceeds the cost to mine. There are several factors that determine whether bitcoin mining is still a profitable venture. When more miners enter the market, the difficulty increases to ensure that the level is static. When miners used the old machines, the difficulty in mining bitcoins were in line with the price of bitcoins. But with these new machines came issues related to both the high cost to obtain and run the new equipment and the lack of availability.
Profitability Before and After ASIC Old timers say, way back in mining bitcoins using just their personal computers were able to make a profit for several reasons. First, these miners already owned their systems, so equipment costs were nil.
They could change the settings on their computers to run more efficiently with less stress. Second, these were the days before professional bitcoin mining centers with massive computing power entered the game. Early miners only had to compete with other individual miners on home computer systems. The competition was on even footing.
Even when electricity costs varied based on geographic region, the difference was not enough to deter individuals from mining. After ASICs came into play, the game changed. Individuals were now competing against large bitcoin mining centers who had more computing power.
