You know m, this is just like in the real world… those that are still starting up got to pay for them to be listed but by the time they get popular they wouldn’t have to pay any money, rather exchanges will list them for free. Another thing is that no exchanger is ready put a shit coin on their list, so don’t even expect that… no matter how much you’re paying makes no sense at all, it’s only good coins that makes it to the list.
