Your message shocked me. I myself received a message via discord from someone who explained to me that he could not withdraw his cryptos on an exchange. He offered me if I helped him give me 0.1 BTC. I told him that he was ridiculous and instead of asking that he should open himself another account on this exchange (which I did not know) and that he had to send himself his own cryptos. I was very naive and explained to him that he could meet people who will not give him his money back.
I'm shocked, but I still did not understand how they wanted to steal me. I just had to open an account on a site and he would send me what I had to give him.
