I guess that really gives you a big lesson for you but the same thing happened for me I got scammed in a different way but also in Telegram. I joined a group where they are buying and selling coins which is legit because I have tried it once and it worked but then it is really up to you to trust the one that you are trading with. I regretted that I have sent my coin first before confirming the person is legit or not. Then I lost 200 coins which worth not much at that time but if I still have that coin I would have more money now. Which is really a big lesson for me that don't ever trust anyone incomes with trading.
