Launch of ABCC Exchange An exchange that is secure and easy to use for both beginners and advanced traders. Though it sounds easy, we felt that there was still a huge market gap for this exchange.

To refresh your memory, the total supply of AT tokens is fixed and capped at 210 million tokens. Below is a summary of how AT tokens are allocated.
