These type of advices have been heard countless time but one thing is that not everyone will adhere to the advice. Also it is important to note that it is not only when you brag about your holdings that people will know that you own some bitcoins. Merely making bitcoin related posts on social media, sticking cryptocurrency related banners in your vehicle or wearing crypto polos can also expose you. But how then can we successfully avoid all these. Satoshi Nakamato had adviced us on how to avoid these linkages by separating our individual identity from our bitcoin address. This can atleast save us in some ways. Meanwhile, it is not advisable to brag about your holdings whether it is bitcoin or money.
Exactly! It is not just by bragging that criminal minds recognizes their target. Sometimes these criminals are too smart to trace their target via the links they gathered from a person who happens to have engaged in social media with crypto related groups and topics and then using his primary account with all the names and photos posted in that specific platform.
I have seen this advertisement campaign about the danger of posting all kinds of information you have in social media, where they prank people by pretending to be a fortune teller using the social media information they get from them and the people that is working in the backend will be the one to feed that information to the fortune teller. People who got pranked get a slap of reality instantly, they never knew it could be used against them.
That simple phishing email and that fake bank representative that's been constantly calling anyone is the prime example that these criminals are also working the best they could to generate a lead.
