Should I trust people I met online?

I was just on Omegle and I was trying out the video for the first time, but i kept my cam off. I met these two Bulgarian brothers around my age. They seemed really friendly and we had a conversation where i could see them and they couldn't see me. I didn't give any other personal information about me other than my name and my KIK username whilst they gave me their Facebook page: https://www.facebook.com/robert.delion?fref=ts

I've never been to Bulgaria and I have no idea what it's like there. Is it a safe country, is it poor...?
They kept asking me to turn my camera on so they could see me but I didn't show them myself.
I've now got them on KIK but i'm not sure if I should continu talking to them and show them who I am. I know how dangerous the internet is.

What do you think I should do?
