If more people started considering everything they receive over PMs, emails, or Telegram to be a scam, we wouldn't be seeing new warning threads with the same approaches over and over again. In other words, scammers wouldn't be doing this if people used common sense.
Nothing is free. Even if it seems free, you are going to pay for it.
People are opportunity seekers but they are looking and receiving it in the wrong way and in the wrong venues, random people sending you an offer on telegram is a big no-no, if you really want opportunities coming in subscribe on reputable article site or visit the announcement thread and check people's opinion on those projects, its time to shutdown random people offering something that are too good to be true without doing research, the Cryptocurrency community has been infiltrated by hackers and scammers so don't easily trust anyone.
