You are right kayden4bit that MangoCoinz needs to be on a exchanges, and we are working on it.
The main thing exchanges want to see is the blockchain (transaction list), so that they can validate coinz and transactions.
MangoCoinz has a blockchain (transaction list), but it wasn't visible till now.
We've been working on a blockchain viewer and we now have a working demo (the real blockchain, but just limited to the last 300 entries) which you can try for yourselves at:
http://www.mangocoinz.com/blockchain_viewer.phpSync, or make a transaction and you will see your username and details being stored in the MangoCoinz blockchain.
The full blockchain viewer will be finished soon.
Best regards, Srele from MangoCoinz.
