You are asking people that have been asking same question without getting the right answer themselves, the only way for everyone to know what will happen to bitcoin is when the remaining bitcoin has been fully mined. Anything you are seeing now are just mare speculation and nothing specific. Although many people believe that miners will be making their money from transaction charges, but we will only know about this after the entire bitcoin has been mined. But personally I believe that there will be a way for miners to get compensated when the entire bitcoin has been mined. So let's not get ourselves worked up over what will happen to bitcoin, because I know for sure that bitcoin will be here forever.
