I personally have no problem with the lottery. But I've just seen similar things in another project recently, and many old investors complained that they could not participate with their investments and have to buy new tokens to participate. I have not been on the telegram channel yet, are there similar problems there?
I guess You're not right. It's just a marketing for inviting more contributors... nothing more... is that bad?
I never thought of it in that sense.. If we look at it many investors would like to join but might have exhausted all their money on early investment during the beginning stages of the token sale. We might just see this as a marketing strategy but core investors might not take this likely as they might see it as not being fair.
