The JACS project has been developing and VPN products for Android, iOS were released. If no exchange to buy JACS, which place I can use to buy JACS if I want to invest into this token?
You can contact the team on tele or you can buy from bounty participants, check the spreadsheet and you will see that many bounters have JACS tokens.
