It's shame to see such a project go down the drain
Several SDA token thefts
No forum controls on overflows
Scammers everywhere with their gmail.com adresses,pretending to be the core team and no bans from the core team.
No feedback from the core team on the forum,as the forum designed for other reasons.
I'm really disappointed with the project.
