The term 'mining' is closely related to how one gets Bitcoin. Basically, this activity is just a simple description of the computer process to get Bitcoin, which is like mining gold.

For the Bitcoin system to work, people can instruct their computers to process transactions for everyone.

Computers are arranged in such a way, in order to be able to perform very complex calculation processes. From there, the owner of the computer gets a reward in the form of Bitcoin.

Because the calculation process is very complicated, it takes a strong computer to get Bitcoin. This is what is then referred to as 'mining'.

However, the Bitcoin system has been set up in such a way that the calculation process required to acquire Bitcoins becomes more and more difficult as time goes on.

This is done to prevent too many Bitcoins from being generated, and eventually circulating. If someone starts mining now, it may take years before they finally get one Bitcoin

On the other hand, it takes a lot of money to pay for electricity and to assemble a computer powerful enough to be used to mine Bitcoin.
