In the society in which we find ourselves today, being wealthy alone makes you a target for kidnappers, and it creates more enemies for you as a human. Your financial life should be kept secret from the eyes and knowledge of others. That way, you can rest assured of your own personal safety.
 
It has already been said that time without privacy matters a lot. It's not just because you want to hide your identity, but for security reasons. If one starts broadcasting their bitcoin holdings, then there is no privacy attached to their investment; they can just add a name tag to all their addresses so that people will notice how wealthy they are in crypto.

Only those who are looking for attention always share their holdings information, and their reason for such is what I can't really figure out as they always fall victim to either being killed, rubbed, or any sort of criminal assort.

Yep — applies to not only bitcoin and crypto, but your wealth in general. It's simply the most nonsense thing ever as all you're going to gain is a bit of bragging rights, in exchange for a dozen of potential problems. Next thing you know your friends and family are now trying to loan money off you, and a kidnapper with a $5 wrench is waiting for you around the corner.

you can often let your guard down when you find yourself in the midst of people you call very close friends and even family because you believe that these people have the same love for you and will respect the trust you have for them. But some of these people are more dangerous than the people you fear outside, because to some of them, they have no respect for the trust you have for them are not even interested in sustaining any relationship you have. As you are careful of strangers, be also careful about the people you call friends and family.

Lol, in the current decade, the most dangerous people are our relatives.
They easily get jealous of our growth and continuously find ways to harm us in one way or the other.
It's not just about bitcoin but we shouldn't disclose any of our assets to anybody (except for the one who can inherit our holdings).

I agree with what @OP said. We can't take risks by telling how many Bitcoins we have. We don't know who is good and bad so we can only be careful. This is not only for Bitcoin ownership but also for ownership of other assets.

We have to be careful not to arouse evil intentions from people we don't know. We should just act as we are and if we want to teach Bitcoin to other people, we just teach what we know and don't need to show them how many Bitcoins.

In addition, by hiding the amount of Bitcoin we have, we can stay safe. No one will be suspicious or have evil intentions. It's better for us to be ordinary people who don't invite any suspicion from people.

One of the most terrible mistakes we make as individuals is disclosing our financial power to an outsider.
Most times we just want to show up or being less secretive, as a person it endangers our life expeccially when we do it among the poor.

Have you ever ask yourself why the rich people stay far from the poor, it's because they are afraid of their safety.
Exposing your financial status is very dangerous to you, remember that people can only ruin what they know, they can't ruin what they don't know.

Only a fool shows his wealth or the amount of Bitcoin ownership he has, because it is very risky and invites problems that can have fatal consequences. And if you look luxurious or rich, it doesn't matter, because
There are many people like this and even poor people can look like rich people.
Because people can become evil if they find out the amount of their wealth because they feel jealous which will give rise to evil thoughts to take it in any way, and maybe only newly rich people act like that because they feel arrogant.
In fact, there have been many cases like this that should be used as examples and lessons so as not to carelessly show large amounts of ownership to anyone, including family and friends.

Many things are happening these days which, we need to be very careful who will share our BTC investment details with because you don't know who is your enemy and your enemy that can do such evils to you can be your relatives or friends who you helped some years ago or the ones you are trying to help to rise like you.

Now that many people know what BTC is all about in the society and, the moment they discovered you are a bitcoiners in the environment, they know you are a wealthy man or woman and they can use anything to get money from you either by kidnapping your lovely wife or your handsome husband that will make you to send BTC as a ransom before they can release he or she which you must pay for the person to get freedom.

It's good advice especially when you don't know what the value of your investment will be in a year or two and believe me, people you show it today will remember about it in a few years.

You may think like it's not a big deal, you told your friends that you bought 1 bitcoin last year at 16000 dollars which was a price of a new motorcycle so nothing special, unless you're dirt poor.
Now it's 30 000 so you can buy a nice car for that, and not the cheapest little thing, but something fancy like a 2020 challenger or mustang. That can make them envious already.

Next year if ETF gets approved we'll be expecting to see bitcoin at 60 000, or even at a new ATH. In terms of cars that's a Tesla S. Many people would kill for that money.
