Hhuh? why dont you mention the exchanges that have most of the volumes. There is Bittrex, There is polo exchange where most volume goes, and if you can not use polo you can use alcurex exchange to trade on polo without having to provide ids and unlimited withdrawals
So basically alcurex's acting like the middle men and executing trades on your behalf. As an example, i use it. I cant not trade on polo as i am from a US state that is banned from using polo. i use alcurex and buy coins in their global market.
