There are always these groups on telegram and at times, you just get added uninvited. The next you know it, boom, your in a new group that you aren't sure you would have loved to be in. Telegram for sure is a home of scams and everybody talks nice and seems to have lots of ideas, vague ideas on everything just to sock you in there discussions and probably make investments.
Word of advice: Never invest off some advice you got on telegram. The unknown is always super risky and the reviews could be from shilling services and a whole team could be working that out on the sidelines.

As for OP, posting links such as yours, I'm pretty sure it sint allowed. You could have input that as a personal text and it would be better appreciated.
