It should also serve as a reminder how easily someone can steal your coin physically from you with cheap weapon if you don't take necessary precautions in securing the fund as single holder. I think it's always better to keep the amount of money you have private... (by private I mean to Yourself alone or to people that keep no secret from you, you know everything about yourselves, you see yourselves as One & can't steal from each other).    Also try to split your coin into multiple keys if you have alot on single keys. Splitting the fund in multiple parts and having special keys for the attackers with reasonable amount that you probably can set to presend to address you control when it's stolen. There should be features to protect from the $5 wrench attack.

I'd recommend the same, depending on your jurisdiction's gun laws of course. As for physical self-defense, two words: Brazilian Brazilian jiu-jitsu. Trust me when I say that you do NOT want to mess with a jiu-jitsu practitioner.

In general:

• one vs. one combat: Brazilian jiu-jitsu
• one vs. multiple combat: if running isn't an option, Muay Thai

You totally missed the point. Read the linked articles and come back here.

Just near my house there has been a robbery case, although it is not a serious problem, it has also warned people not to brag about anything on social networks.
Like it or not, we are still living in a society with many potential risks if we do not know how to equip the skills to protect and combat it. Earned money is also not happy because there will be people watching, and criminals will not forgive you if you have a lot of money.

In my country, weapons can be used when absolutely necessary. To put it very simply, I can only shoot a pistol after the wrench gets stuck in my head.
The weapon is very effective at close range, because while I pull it out, I will get a few stabs with a knife or a wrench.

I heard that in the USA you can shoot a person if you are in a car, and he breaks your car with a bat.
In Russia, in a similar situation, the criminal must first inflict serious damage on you, so that this situation is a case of extreme necessity.
And still after the shot there will be a very long trial in court.

I've always kept my cool whenever the market is pumping. I've always thought of wrench attack or worse than that if I'm too showy on social medias.
But with the craze of NFT gaming, I've got a lot of friends sharing their gains and that's totally fine to me. Although I don't do the same thing that they does, I wish them that safety at all times and as well as to me too. It's always better to remain low when you've got thousands to millions of bitcoin/crypto assets.

With the ideology that every Bitcoiner is a millionaire, then I consider it too much of a risk to tell people you have Bitcoin, or you deal on/with Bitcoin, I have actually had individuals discuss about how much money they have in Bitcoin or have made from Bitcoin without understanding the risk they run doing that, I'll be in such discussions and wouldn't utter a word, it's that much of a secret that even most of my close pals do not even know that I do have some Bitcoin in my possession, there are many ways to protect yourself from a $5 wrench attack, but the preliminary step and the biggest one of them all is keeping your mouth shut about how much Bitcoin you have, if people do not have the perception that they can take something valuable from you, then they wouldn't bother attempting to rob you.

I don’t think there was ever a time when it was good to tell people how much you have . Doing so, you’re letting them know that you are rich and they can easily rob you and get away with lots of money in their pocket.

So, it’s best to keep things like this a secret, and only people that are very close to you are allowed to know things like this. When I say people who are close to you, I mean your family like your wife and children, and not just anybody, even in your family you also need to be scared of some of them because they can also back stab you. Whatever I am making in investing into Bitcoin is just my business and no one else’s business, I only do it to take care of my family so it’s not the public’s business.

Ditto. There will be A LOT of bragging to friends in the younger teenage years of most kids. Bragging about girlfriends and winning fistfights can also end with "my parents are rich and has a crap ton of crypto".

You have a point but that'd probably only work if they've randomly picked someone to rob, as opposed to specifically choosing someone as their target + there's no guarantee that they'd not kill you after giving them what they wanted ^{[unfortunately, it's always 50-50]}!

Both of you are probably correct and he isn't the first one to intentionally ^{[convenience]}/unintentionally ^{[limited knowledge]} store a significant amount with a custodial service: California resident lost roughly $24 million in cryptocurrency

Not in where I am at the moment ^{[unfortunately]}! If you harm the robber in any way, they can sue you ^{[it's ridiculous]}!
^{- Your best bet is to pin down the robber, without actually hurting him [easier said than done]!}
