Had a conversation a few months ago with an administrator from a Discord group, it was the one that I almost got scammed on. He told me that it's a common occurrence, a daily thing, even in their group, and quite a few people contacted him that day, to report the scammer, which led to thousands in losses.
I also dun goofed and inserted my private key on some random website which did look legit, but it was stupid to say the least. I'm still unsure on how I fell for it, however, I was one of the lucky ones, who after conducting such a stupid move, immediately moved any funds and unstaked any assets to a new wallet.
It was a horrifying experience.
You need to be careful and very attentive, because scammers are constantly coming up with new ways of deception. In the telegram settings, you need to disable the automatic download and installation of programs, because in this way you can install a malicious program that will give scammers access to your wallets. Never be in a hurry, always check and think a few times.
That's the main reason I don't join groups anymore, Discord, Telegram, whatever it is, except it's an emergency or need specific assistance, which is rare. Anyway, the internet is full of scammers, so it's not surprising that they also appear in cryptocurrency groups, however, they seem to be more common in groups regarding tokens and staking platforms (Beefy, Supra Finance etc.).
