Like DaveyJones said, coins like BCN require, next to the wallet address, addionally a payment ID.
Exchange
Minergate
I just took some BCN out of Minergate to HitBTC, deposit arrived a few minutes later.
What exchange did you try to send the coins to?
If you forgot to enter a payment ID, contact exchange's support.

" if you forget to do that then your bytecoins will be sent to the common exchange wallet, and you will have to contact the support and individually solve your problems."
Good luck!
