The team wrote about the opening of the category for the Bounty campaign in Telegram. It is likely that this also affects interest in this group, but the number of participants is still very little because of the passivity of the project team.
yes, It's quite possible. I think the team is announcing the opening of the ICO, pre-specifying the details. Telegram is a great way to quickly spread new messages.
I would like to join the group after the beginning of active discussion of the project. I think that investors will have a lot of questions to the representative of the project.
