I get messages everyday in Telegram.
Most of them approached me as investors, group admins or affiliates.
One way to detect them is that they will approach us first. And they always start with 'Hey User'.
Real investors or admins dont simply approach other people until we ask for their help first.
the point is never to trust people who suddenly send you a message and then they promote to take part in their investment system. Those are all lies. If you telegram, "Report & Mark as Spam" is the solution. Just leave them, you wont waste your time for nothing.
