We are planning add 3-5 coins to our exchange for free, which coins that should be ?

I should choose some newly exchange-less coins (because of collapsing or pausing exchanges). Guess some Freshmarket users still have some coins. And OpenEx and Cryptorush users may become impatient as well. To speak for myself, I don't know what to do with my
Alcohoin (ALC) (from Freshmarket) or my
Binarycoin (BIC) (from OpenEx). Maybe you can attract other users with these kind of coins as well.
PS. I though we were supposed to withdraw the coins that are not traded anymore on your exchange. Why does it already take 5 days to withdraw my LOT? I think this is part of being supportive to your customers as well.
