New exchanges and multiple exchanges are good for more than just liquidity.  Adding exchanges for various assets makes that asset more available to the general public.  Some people only use certain exchanges exclusively so until that market is made open to LRM there can be some people who simply would not acquire it. 

Cryptopia is a really good exchange to be a part of because of how serious they are with KYC.  However, other smaller exchanges are good to and people should be excited to see their interested assets listed anywhere.
