he has always being showing his self to be a Bitcoin boss in my area and people have been according him that respect to be someone that's doing well (financially) and it is very obvious so to speak.
I'm sorry about this kind of incident, I pray for the person who was attacked so that he recovers quickly. I read your post completely but the main point I got from it is that the victim was known in your area as the “bitcoin boss.” The mistake here is the issue of self-publicity, because being called a bitcoin boss means people believe he has a good amount of bitcoin or money. In the crypto world, one major way to put your funds at risk is by making yourself too public. If the victim was known as the bitcoin boss in the area, it suggests he had a lot of money and people around were aware of it. That is why the attackers likely did this to snatch the money.
Overall, maintaining privacy is very important, then many problems can be avoided. There is no need to share with others how much bitcoin you have. Whatever can be done through proper privacy should be done that way.
