I never scammed because every time I carefully in every step when I have something to deal with especially in cryptocurrency transactions.
But here is I can share you when I was almost fooled in telegram users that want me to withdraw his bitcoin on that he said exchange. He said to me that in their country he can't able to withdraw due to crypto banned. I make an account on an exchange he said and he transfers his bitcoin(3 bitcoin) to my account through my email address used. But, when I was withdrawing it, the site asking me to deposit first before I can withdraw the fund for 0.1 bitcoin. I was confused and doubted at that time, then, I contacted my friend who expert on looking legit website he concludes that the exchange I used is copycat and fake exchange.

A lesson to learned: Never been trust those in people in the telegram, a lot of scammers out there.
