In addition to the exchanges listed on the CMC, there are many other exchanges.I have a question WHY do we need so many exchanges?What do You think the new exchange will be able to attract potential users?
We don't really need too many exchanges, they just there to give us options to where we could buy/sell out crypto. New exchanges attracts users by offering features better than other exchanges such as lower fees, faster transaction, and more.
Also to give more competition, as you said the crypto community is actually not in need of all these various exchanges however the appearances of many new exchanges could give competition that will definitely benefits us as a cryptocurrency users so there is nothing wrong with that, also that many exchanges could atleast find and exchange information about security I guess, so that's better.
