miners are getting payed for every transaction. if you don’t include transactions fees your transaction will spend a lot of time in limbo and may actually never be mined. the way it works, let’s say you have A bitcoins and you want to pay someone B bitcoins. you create a transaction that say: I want to move A to B and A-B-fee the miners see it and see the fee. it gets included (ie mined) in a block. actual example 50BTC -> 20BTC + 29BTC when the miner mines it, it will send the tx fee to its own wallet also, most miners sort transactions by the most profitable to less profitable and mine only the most profitable ones
