I've participated in so many bounty campaigns and invested on some tokens coming from ICO, but I notice that so many of these projects are not or stopped updating their Bitcointalk announcement thread but they are so active in their telegram channel.
Do you think this is good for a project in general, let's admit it, Bitcointalk topics always shows up in search engine like Google while on telegram you have to scroll a lot or wait for an answer and they are missing up some potential investors who first look on Bitcointalk for project that they want to invest in..
If they are not announcing anything transparently then you can call them as scammers because most of these activities comes from scammers only.Don't wait for them because they will keep you in that situation and also will make you to believe that their token is going to be listed soon and soon but they will never.
