Thank you for listing BOXY Coin.   From what I can tell Start-Ex is trying to build a exchange for real crypto projects that are just beginning their crypto lifecycle.  They offer free listing for solid projects that are not already on an exchange.  It seems they are in no hurry to list a bunch of scam coins just to increase volume.  Quick deposits and withdrawals and support service from my experience.  If you are curious you should ask some questions in the friendly discord chatroom.
