Yeah, if your appearance look like foreign tourist, some of them might be thinking ah you are rich.. hahaha
Basically there is not. Of course unless if you go to the dark areas or the area which are being trending with the crime at that time. That should be carefull because you maybe get robbed or something.
And wear polite clothes if you are outside the international destination areas such as bali etc, if you dont wanna get any stares along the way, don't wear any flashy appearance/branded things or don't wear jewelry, and keep your bag/wallet at front side.
Well, I guess as long as you don't do any weird things from local perpective, it's quite safe.
Anyway, I think you can search any review from foreign youtuber in youtube that had visited here doing backpacker alone or fancy trip together with their partner. Or from the tourist who had live in here for long time. I guess it's really helpfull as a guide. :)
