Criminals won't be trying to get your bitcoin off you if they didn't know you have bitcoin in the first place.

Be private with your bitcoin/crypto holdings because no one really has to know.

And because of that, always remain humble and don't let other people know whether you have Bitcoin or not. Because an incident like this happened in my city, where a Bitcoin billionaire was on holiday and then the place where he was staying was visited by several people and he was held captive together with his girlfriend, his Bitcoin worth 200k USD was drained by the threat, fortunately his life was still safe. So yeah the best way to avoid cases like this is to stay alert and don't let other people know how much bitcoin you have.

And by no one, it is not only at strangers that we meet on the street kor randomly that are referenced to here, people who we we call our friends and our family members still have to be feared because they can do to you what strangers will do to you if you become too careless and trust blindly as they are humans too. People can never steal what they know you do not have, the reason and need to be careful what you let people know you have.

I feel sorry for this guy, RIP! But this continues to be a lesson for those who believe they can be flaunting their wealth, especially the digital assets like cryptocurrency that is decentralised, the danger of robbing them or even killing them is high. Thanks to the CCTV camera that captured the perpetrators, it could have been untraceable in some environments, so we should be private with them even as Bitcoin preaches privacy and anonymity.

Practically as you asked, I have these few tips;

1. Never disclose your Bitcoin asset or its worth to anyone and make sure you only buy your Bitcoin from external sources that can never trace it to you.

2. If you make the mistake of being traced and have a huge number of Bitcoins in your wallet, I advise you to mix them and send them to a self-custody wallet afterwards.

3. Show restraints when Bitcoin discussion is mentioned in public, and even among friends, the enthusiasts and lousy mouths will always be the number one target.

4. Do not have Bitcoin wallets installed on the gadgets you take to public places if you have a huge value of it in them as anyone may be a victim of robbers and unforeseen circumstances at times. Checking your phone alone could put you in trouble as cryptocurrency is the aim of some evil-doers now.

Use a bank instead. That's why people like banks. Physically guarding your own savings is for the birds.

No, it's not. Your money can be stolen, either by break-in, or at gunpoint. Our you could misplace it.

Almost all Americans keep their savings in a bank or other financial institution. These companies specialize in keeping things safe from criminals, and will give you your money even if they get robbed.

Maybe banks don't work correctly in the country you are from, but they work just fine in the USA. I would never keep any amount of significant money on my own person.

I just read the news on cointelegraph.com and what I observed is that some bitcoiners have been killed over the years and their bitcoin stolen by the robbers. Just like what the advise on the post says it will be better for us to keep our bitcoin involvement secret and their is no need to start preaching about bitcoin anymore because it is now popular.

Also staying away from bitcoin seminars and meet ups will be better because you don't know who came their to find their next target. Avoid anything related with bitcoin discussion anywhere you are apart from trusted people. The bitcoin in your wallet is mute.

A total stranger will not randomly guess that you are hodling Bitcoin, it has to be people who knows that you hodl it. This was one of the lessons that I learned as a newbie in this forum, never to announce my Bitcoin in public, this is because your private keys is the only proof of ownership, if it changes hands that means that you have automatically transferred the ownership to whoever that is holding your seed phrase. This is one of the burdens of being your own bank, there is no centralized authority that you can report to, when you're robbed of your seed phrase that can stop the criminals from stealing your Bitcoin.

I guess it's because of the ethnic, the victim is a Moroccan, high likely an Arabian.

Middle east people faced discrimination in Ukraine., if they robbed white people, I don't think they will kill the victims.

What's external sources?
 
1. The robbery will force the victim to send the money to their account.
2. The robbery will force the victim to withdraw the money on ATM till maximum limit.

It's important to remain anonymous and humble because it's unlikely that criminals will target you when they don't know your assets. It's just that not a few cases today occur when we try to show off and show off our portfolios where consciously or not it will invite a lot of people with various intentions including harm.

This is clearly quite depressing but there is nothing that can be done because after all the cause and effect clearly exists so that this can be a good consideration for us to be more humble so that we do not become a target just because we are too much to show off the assets we have consciously or not.
This does not mean that I justify what the criminals do because indeed it is one of the heinous acts and they deserve the punishment, but on the other hand we must also be able to limit ourselves so as not to get too carried away when the hype so as not to cause malicious intent from others because indeed it is an important thing so that our anonymity must be well maintained.
