GTA CLASSIC - $GTAC
SteathLaunch on ERC20 

About us: We are huge fans of GTA universe and with fresh news we aim to help main Rockstar team, to get their Cryptogame working, we have team member who is working with them, and when our token success we will have a good chance to become this P2E game that Rockstar Announced. We will use all our connections to get $GTAC a huge success, we will use many Tools for this, such as community based token basis, huge utilities, Low taxes and much more !
