Did you hear about IronX and WPP? Both came in 2018, and both raised good money from ICO! From February 2019 to now, in IRONX telegram group 2-3 admins are active, if you ask about any update, they will reply to you "Our Technical team is working behind the scenes, very soon you will get an announcement"
Then I left their telegram group in March 2019, then a few days ago I was remembering all projects of 2019 then I joined IRONX telegram group again to see the latest update, you know what, admins are still active and giving the same answers what they copied year ago!
I don't know how many days I will remain mad after seeing this (Sarcasm)
Now, about WPP! Admins are very active for nothing. They raised 59 Million USD, just listed on Digifinex exchange and that's it, their coin value became worst, trading volume less than 1K USD! Whenever you ask to update, they will reply to you with shitty information, if you ask them back, they will ban you!
Seems like the admin in the telegram group you were talking about acts like a bot for answering the same phrase whenever you ask for an update. As a bounty hunter, it is really important for us to secure and keep on track with the updates to that whenever sudden changes happen, we can adapt and adjust to be able to get along with any update they will imply. I haven't heard of such projects you have mentioned but it seems to be suspicious that the team is more likely avoiding to give out necessary information you need to know about the project. Bounty hunting does not end up after you have done your job on the promotion because as long as you haven't sold your tokens yet from that certain project, you do still have concern to know what is happening or the progress of the project. So such necessary information must be fully provided by the admin in the group to keep you updated as well as the other members.
