I am pretty sure he/she means that this has been talked over and over from time to time and most of us seem to understand that even if that would be possible, listing is not the right move because the costs are more then benefits. There are several points that have been mentioned for and against in this thread.
But isn't registering there actually getting bigger profits in the future because this is a pretty good idea for the long term even though it does require a lot of money but I'm always sure that a good development will definitely require more money and time not a snap.
What makes you believe they won't benefit because the costs outweigh the benefits?
Pros and cons or differences of opinion in this thread will always exist because it is a natural thing where everyone must have their own way of thinking which is considered the most correct and appropriate so that whatever happens if for the sake of progress and development it must be done.
It depends, if you take the time to look at the reaction of other coins after being listed on a big exchange like binance you can see that some of them showed a good behavior and the price of those coins went up, obviously this is the kind of behavior that anyone that is holding one of those tokens wants to see, however it is also very common for a coin to dump dramatically after is listed at binance as now whales can manipulate the price of the asset more easily, and if the coin does not have the volume to resist such manipulation the price can drop to very low levels and never recover.
