Telegram provides maximum opportunities for editing messages - yes. There is almost no regulation - yes. But where did you get the idea that a third-party service should be responsible for what you invest in shitty projects?
If there is not a single negative review, then something is wrong here. Try to find out why, if your message was deleted - draw conclusions. You should always think with your head, no one will do it for you.
Ophh brilliantly put, it's like TG for TG, a place where - despite the lack of whitepapers (as if I read them).. despite the lack of audits, as if they guarantee shit.. there's - a closed group of owners, investors and prospective investors who are willing to share their views, facts, and opinions, so that you can actually find out about the project your either already in (for other reasons) or looking to invest. And your finding out with living information, that is to say a live feed, so that its not only potentially highly engaging, its also very revealing if don't read everything at face value or actually use it to ask direction questions and demand face value. Live.
Its funny how so many groups tend to go through the same motions on TG, you can read the vibez dude. Anyway tbh I'm one of those guys who ends up joining ALL the groups on TG, being apprehensive to leave because im scared ill miss something. But having to deal with a torrent of useless (to me at least) chat to get to the good stuff.
