I can’t see the telegram exchange group own: this one happens locally where you are invited into a group and then you will see them buying and selling cryptocurrency coins and tokens with a much better price than almost all exchanges then due to naivety and greediness you end up buying or selling to them. The group will have fake people in it and a self claimed escrow. They will ask you to send to the escrow first and once you do that you will just be instantly removed from the group.
Telegram is a well known fraud media and I wonder what the heck the team is doing to clear that belief people have about their app. It's one among the reason why I don't fancy it and hardly believe whatever I see coming from there. I once joined one group where they claim to give signal and unfortunately, I fell for it and was scammed.
I held bags of the shitcoin and it just kept dumping and dumping until I just exited at one point 
Lol. This was my experience back then also. The shitcoins I gather hoping for pump is unaccountable to the extent I have to abandon the wallet/address so I can have peace of mind because sadly, I use to check on a daily basis before I eventually woke up to reality and realized I was scam. Some bad experience like such is actually an eye opener for a beginner and it taught me a lot that myself and anyone under my guide will not fall for again.

The other way I was scammed was speeding my time doing tasks for a project, and they just didn't pay. I value my time, once it's wasted, it's similar to losing money
This must be bounty I guess. Time is very precious, should be utilize well and dedicate to something worthy because once lost, it can never be regain again.
