It's just uneconomical to be able to mine Bitcoin. The earliest mining was done by ordinary home computers. Now that there are professional mining machines, computer mining is not competitive at all. In terms of current electricity bills, the cost of digging a bitcoin on your home computer may be many times higher than the market price of bitcoin. Therefore, from the perspective of market economy, it is completely meaningless to mine Bitcoin on a home computer. It is recommended to consider going to the exchange to invest in the secondary market. There are many good exchange control options, such as coinbase, ZB.com, bitmex, etc.
