You can read and discuss more BIS issues on their discord. However the moderators of their discord and not very welcoming of suggestions. Seems a little shady, recently they even spoke of banning people who brought up issues. I am not sure how moderators are chosen but its a bad look for the actual crypto. I do agree a roadmap is needed and not having one makes no sense. However, the github is active and it seems like they are trying to get on a new exchange and fix some problems. These things take a little bit of time even if people think they should have happened already.  To me this is a high risk investment because the team or developers seem disorganized and website looks outdated. The idea behind this coin is great and this could be a real winner.
