The only problem with people is bragging. That is the number one culprit why people who do not know the victim's wealth find to know it. When it comes to financial information, we should be silent about it. Be a low-profile person and let them think that we are poor people, at least that will save us from many headaches and life-threatening situations.
We know who we are, so it does not matter whether they think we are poor as a rat or whatever, it is better to be belittled or looked down (even if we have more financial capability than they are) than to get into a dangerous situation.
Absolutely, and with easy access to social media, people feel free to flex whatever they have, and even if the aim is not to brag, still it would make people find it envious especially if what you are posting are those that they don’t have chances to get. So the best way to remain safe is to be a low-key person. Be secretive without letting other people invade your privacy.
There’s no need to brag anyway, as not all people can be happy about it, some would end planning a secret attack on you.
