AI scam is a new form of an old scam and it is not limited to Telegram. In fact, someone who I though was a friend on Facebook once sent me a chat asking me to support them in a contest by voting. The link they sent required me signing in to Facebook using my email and password. After signing in using my email and password, they asked if I had done it, and immediately, my instincts told me something was wrong and I quickly said no and changed my password. They kept asking if I had done it and I ignored them. Later, the account was deleted. Apparently, that was the tactic the scammer used to hack my friend's account and wanted to use it to steal all the accounts of their network.
That's not your friend for sure, he could have imitate him, or his Facebook account has been hack. I have seen this kind of attempts before, from my cousins account but I suspect it right away when it started to ask money.
The rule to protect yourself should be "never click links from unknown or suspicious sources." It is better not to allow your curiousity have the better part of your sound jusgment. Better err on the side of caution, especially on social media.
Yes, that's one, and even if the source is from someone you know, you should not trust anyone specially in the world that we live in wherein there is a lot of scammers and hackers and criminals who wanted to steal our crypto.
