Ok this is good point you bring up. Businesses have cash and inventory, yet most never ever are robbed. So a sign saying it accepts btc isnt gonna change that. And everyone knows all businesses have video surveillance. Whereas a person can be followed to whereever the criminal feels safe attacking. And, your btc sticker car will eventually be at your home, letting any would be attacker know where you live. Im sure you have heard of peoples' homes being robbed after posting expensive christmas gift photos online. Yet, how often is say, a Walmart, that has those same items, robbed? I really dont have a perfect answer. And everyone's situation is different. But I just think people would do well to not advertise certain things. Especially online. That's more what I was getting at then a sticker on a car or shirt or whatever. Online you have not only run of the mill criminals, but also government agents. But basically, you (or whoever) has to decide what is best for you. Im just offering suggestions that can possibly save people serious troubles.
