There is a way you will flaunt your wealth; you will be a target. You can't completely hide your physical assets, but if you don't talk about them, the masses won't know about them, maybe just a few people. The only way an asset is more publicized is when you talk about it and give people the impression you own the asset. There are a lot of people who have more assets, but because of the lifestyle they are living, the public doesn't even know they have such assets as what they really have. We can help ourselves to be completely private; like in the case of Bitcoin, if you are very private, no one will even know you have Bitcoin. You may not completely hide physical assets, but you can keep Bitcoin private without anyone knowing about your Bitcoin investment.
Of course you're right, there way individuals can show up there wealth, it becomes an act of endangering oneself, in as much as I agree with you that wealth can not be hiden to an extent, if one starts showing up like that, such person should make sure that he has reach the level where he can afford security that will be guilding him because, once people start noticing that one has reach to some level of wealth with the evidence on ground, the peron should expect attacks robbers can even come visiting, there will be different confrontations.
Anyone in his right senses can never discuss his assets with anyone, Bitcoin asset are secret why will anyone even open up to people about his Bitcoin asset that a very careless way of living life, let's note that people out there thinks that once you have Bitcoin no matter the amount you are rich, I think that's more reason why we should all be careful about how we talk.
