It's fine to post a problem in a group. Sometimes others will able to help even no need for admin's response just in case it's not internal stuff and can categorize as a general problem.
It's just that always used common sense along the way.
Yeah, let's stop chatting because somebody might start talking with us and he will try to scams us.
You can safely ask for any of your problems, the risks start when you're sharing private details when you give strangers access to your accounts, keys, etc etc.
It is risky to ask a stranger in a station what time is it? No.
It is risky to drink after with that stranger in a shady bar in an unknown town till you fall in a ditch? Yes!
After few minutes, fake admin pm me and said want to help me. He ask my email in exchange account and i give it. He said there have problem and i must send bitcoin. So, i check their telegram profile and in the bottom not have Group in common. Then i block and report him.
So the possible problem was not you seeking help.
The problem was you arriving at a stage where you almost trusted a stranger with your coins.
The topic should be more like..."Check twice to who you're speaking in telegram".
