In terms of safety predominantly but even just in general. Also I’m not talking common sense stuff like carrying around valuables like expensive jewellery etc.
I’ve seen some travel videos/blogs where people advise to keep a low profile and ‘blend in’ with the locals.. even saw one where they said don’t wear a baseball cap because they’ll know you’re a American.
My own two cents, anyone that’s a local will know you’re not from there pretty quickly even before you open your mouth to speak. Those who want to pickpocket you already saw you walking out of your hotel or taking photos at a tourist site.. multiply that by 100 if you don’t physically look like the locals .. It’s almost futile to try and “blend in”, and even if you could why would you?
