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.
You are right, is just like how you can't predict bitcoin in the future. We can't know what bitcoin will be after he as fully mined. we should just focus on presents currently. We should not be thinking how bitcoin will be in the future let us invest and get profit. If you are benefiting from something, no be thing you think about how he will be next since in didn't affect your investment and he still moving smoothly. They will always be and alternative about bitcoin after he as mine fully and making others not to feel discourage on investing in it. With how i get believe on bitcoin I don't think bitcoin will stop since network will never stop in the world, that is how I believe that bitcoin will stay forever and people will still be coming to invest in it without stress again. Let us always focus on our goals and stop thinking otherwise about it, nothing can stop bitcoin and he will continue moving well.
