Hello my dear friend @chaalee
Suppose you have 10 bitcoins, you will now send those bitcoins to someone named Tanim. A certain fee is deducted from it. Now the question is who gets this fee? The said fee is received by the minor. From the moment you send bitcoins to the time your friend Tanim receives the bitcoins, the transaction process that takes place in between and the amount of power that is spent to validate and process it is done by many computers sitting at the other end and sitting in front of that computer. He is called a miner - that is, his computer completes the effort and receives this additional fee as a gift.
I wish you best
Best regard @jannatmou
