David Bollinger If you want to mine Bitcoin directly, youll need some mining hardware. When Bitcoin first launched in 2009, people were mining at home with basic CPUs. As more miners entered the market, the Bitcoin difficulty increased. This meant that CPUs were no longer capable of solving mining equations. Instead, miners had to upgrade to GPUs. Calculating the Bitcoin Mining profitability helps evaluate the mining rewards and mining costs. That can be done with the help of a Bitcoin Mining calculator, which requires the user to fill in details, including Bitcoin mining hashrate, consumption of power in Watts, cost of electricity in $/kWh, and maintenance fees. The hashrate values are adjusted, and an appropriate mining hardware device is selected from the ASIC Bitcoin miners list.
