I realize I am actually an idiot but I didn't check how dangerous it really is before doing it. Anyway all those services seemed legit.
I sent passport id photo for kyc on skrill and paxful, and also bitcoin exchanger in estonia(EU). I picked the last one on popular site bestchange.com, it is working for 1.5 year...
Do you think I have to change passport or this is just a panic? I am thinking about this all for several days...
Bro haha you just removed the idea of annonymity with what you did right there. I'd ask of you to edit your information temporarily in your social media accounts and not post anything about your travels and whatnot for now. Just to be on the safe side. Also try not to send your idphoto in any type of exchange site, ever. Again. Not unless it's a trusted and official one where you can guarantee the safety of your private information.
