Novaexchange has their ETH wallets in maintenance at the moment. We have inquired about how long until we can list ERC-20 tokens again and are waiting for a reply from them.
We're currently undergoing procedures for becoming compliant with the HitBTC listing requirements and we are also applying for EtherDelta very soon.
Still can't register on nova right now though. and 10btc to get listed on an exchange??? $40,000 just to list?!?!?
