Been trading on ABCC for a few days and it has been quite pleasant so far. Really like the concept, releasing tokens through trade-to-mine and beside that the daily dividends, damn!
If you sign up at https://abcc.com/, you can get back 10% extra of your trading fees with my invite code (e85d57).
One of the ABCC terms:
