When you request a transaction you also offer a fee. You get to set the fee. If miners don&#x27;t like it they don&#x27;t have to include your transaction, and if that happens your transaction will not get confirmed.<p>After no more coins are mined, miners will be relying entirely on transaction fees. At that point, competition will show us the real cost (and electricity used) for transactions.<p>Right now transaction fees are low(er) because miners can offset their costs against the coins that they mine as well.
