First of all, I regret this situation! It's always very annoying to suffer a blow.
I'm from Portugal and I also spoke with him via telegram and here on the forum.

Since I never gave him much confidence and so I did not analyze the conversations and information indicated by him.

When I learned about this topic, I went to analyze the information I have, to see what I could help.

And making a more careful analysis of the way he wrote, despite not being a bad Portuguese, it was a very careless way. Which is not normal.
As I said at the time, I understood that, but I didn't care, because he never asked me for anything either.

He also told me that he was from Vila Franca de Xira, but honestly, I have my doubts.

His telephone number associated with the Telegram is +31 687767940. This is not a Portuguese number. I hadn't noticed it before, until today.
This is a number from the Netherlands and I found other information that regrettably indicates that it is possible fraud:

Today I still tried to talk to him via Telegram, but he didn't answer of course. I regret not having more information to give.

But if I can help with anything else, just say so.
