Say one has to send 35 dollars to complete a transaction but the priority fee is 25 dollars. Could one send the 25 dollar fee plus add an extra 10 dollars to make it so it all adds up to 35 dollars? This way so one doesnt have to send a total of 60 dollars?
I believe fees is calculated separately. The amount to be sent should have extra payment for the transaction in order for the transaction to be processed. I agree that if you want to save a huge amount, you better persuade the other party to accept altcoin and convert them on the exchange once accepted.
