Wrong, Since if they add more coins as much as they can this exchange may became a "Shit Exchange" since they are allowing scammers to get in and many noob peoples will get scam by hype scam coins, that's why I will agree for that listing price ask by them since it can censore all things to minimize the scams.
I have seen some good projects, they haven't raised much (like $1MM), the project works and people are working on it, but they just haven't got much for marketing. So honestly I don't think it's fair to ask all their money for listing a token when they were able to spend them on developing) $10k listing would be more than ok, scamers won't pay such a price either and still that is not as much as $100k
