so how can protect offline wallet ?

First of all, please be more specific on how did he lose those Bitcoin.

As per my understanding there can be only two reason, either he has shared his privately accidentally or has send those Bitcoin accidentally on Facebook.

Never share the private key cause it is meant to be private and never talk about Bitcoin to strangers.

Follow the above rule and be safe.

There are many ways to protect your offline wallet. The first thing you should do is to make it private and never share it to anyone; in this way, you will avoid to get robbed. Also, do not trust someone who anonymously sending you a link, it may be phishing.

I cannot think of ways how can an offline wallet be hacked or infiltrated by just chatting on online facebook messenger. As we all know offline wallet  are highly resistant to attacks and also the way you tell your story lacks details. I guess he is using a cold wallet and possibly he was a victim of hardware keyloggers. Another possibility is that somebody knew of all the details about his offline wallet and just snatch it away from him.

Come on, this is kindergarden stuff.. It's kinda obvious you shouldn't share personal information with strangers, especially your online wallets? Telling somebody your Bitcoin account is as nonsense as telling somebody your credit card information..

Anonymously or not, links should always be verified before entered. It is more likely for your wallet to be penetrated by hackers or viruses than having your funds being stolen after telling somebody your private key or seed. By "offline" we usually refer to a Bitcoin wallet on a PC that's never connected to the Internet, but the OP apparently refers to something completely different.


If you have a PC that is not connected to the Internet, then you don't have much to worry about. Just take enough care when plugging in any USB stick because it could be infected.


If the PC your wallet is set up onto is Internet connected, then you must take precaution because fund loss isn't something unusual to happen and you could turn into just another victim of it. The best thing you can do is buying a hardware wallet if you are holding large sums. There are a few safe hw wallets around with different price tags based on which cryptocurrencies you are using. If you aren't holding large sums, then it probably isn't worth the costs to buy a hardware wallet but you should know you're always vulnerable and being a victim of keyloggers or cryptocurrency-stealing specific viruses could become a disaster for you.

A good option would be taking an older smartphone, resetting it and turning it into a cold storage. Most of us have an old phone lying around we haven't used in a very long time, and that could be turned into a way of storage not as safe as Trezor or Ledger, but surely safer than a wallet installed on a daily-driver PC.

I believe the OP meant the wallet was closed and their funds somehow vanished. As far as I know, you can grab the "wallet.dat" file from a specific directory on your computer, but that might be an outdated thing as the last time I backed up my ".dat" files was somewhere around 2014. If you can still grab the file and the wallet was not encrypted (if you encrypt the wallet, the ".dat" needs a password to be unlocked as far as I know), the OP's friend might've been a victim of hacking.


Although the hw wallets aren't very cheap though, I highly recommend using them. They give you the feeling of safety no other way of storing Bitcoin does.

I have never heard news like this before where your friend lost a coin in his wallet offline when he surfed with Facebook mesenger maybe your friend gives privacy to others and maybe your friend is not careful when storing his wallet coins and maybe when your friend is chatting Facebook Messenger appears to be chatting with the wrong person where that person can hack your friend's software.

Hoe did your friend lose his coins in an offline wallet while chatting on facebook messenger? You should've elaborate what happened. The only way I can think how your friend lost his coins is if he saved his private key in messenger, or on his computer which might be hacked or has malware. That is why it is safe to keep your private key somewhere that is not online..

There might be two things being stolen when you use an offline wallet, your friend gives a private key to someone, or your computer has a virus. Giving someone a private key is the stupidest mistake made by a user. Private key is something that is very "private" and confidential. no one can know your private key including official third party. And the second is a virus or malware, I have experienced one of these things, I installed an application sent by my online friends, and it turns out that the application has malware that allows them to record all activities that you do in your computer, including recording passwords and private keys that you enter.
how to protect them is to install an antivirus and be careful of applications and suspicious links

Even if you click offline links there is possibility that your wallet get robbed? I do not trust any of my friends seeing my wallet because even them can click that anonymous links that they get robbed. but mostly they are aware of this. I hope that everyone will know how exactly protect they're own wallet too not just me.

[Genemind]

You should have posted the kind of wallet that your friend has. If it's an offline wallet then it might be a hard wallet. I wonder how did it happen. Facebook can't even access an offline wallet. Hard wallet cannot be hacked unless someone else robs it and knows its private keys. You should never entrust your wallets even your private keys with someone that you don't trust that much.

[Janation]

What?

How did this happen? That fast?

Offline wallets can be hacked but I don't think it happens that fast. If that really happened then I guess that is not in the time or the people he is chatting at that moment unless you are sharing valuable information about yourself or maybe about the wallet your friend are taking care of.

For me, the simple and easy way to protect your offline wallet is through saving its private key or passphrase then the put the offline wallet in a safe place. I think it's hard to restore his coins and no one knows who gets those coins. Maybe, his chatmate tells that he will make your capital double once he sends his coins so basically, he may got scammed by his chatmate and for me, it is only the reason why he lose his coins.

[Fappanu]

How did this happen? Just by chatting your friend has lost a coin?

Maybe he gave her his password or his private key. Because this is the only possible reason why he lost his coin.
You must provide enough explanations to give you enough solution.

[FlightyPouch]

Did he click any suspicious links? Any suspicious emails or messages? I am also wondering if that happened while he was chatting or it might be happening for a while now and you just noticed today? I don't really know what happens but one thing is for sure, you need to secure not only your wallet but also your PC as well.

[fiulpro]

Okay I cannot stress this out

Never install any app from sources you have no idea about , don't click on suspicious links , don't connect your mobile to Bluetooth of person you have no idea about , don't let anyone play with TeamViewer on your mobile.

These are like the basic things that you ought to do to protect the privacy of your mobile and everything alike.

Probably something like that happened. People often don't even pay attention where and what they click and later they are surprised when something happens. Awareness of security needs is extremly low.  Education of people about security and potential issues in virtual space is a must.

[Lucius]

Even if your friend uses a $1000 offline wallet, it won't protect him at all if he gives away his private key while chatting. Though I doubt he's that stupid.

This is probably about misinterpreting what an online wallet is and what is an offline wallet. OP is very likely thinking of desktop, mobile or hardware wallet which in this case can be very easy hacked by asking the victim to send his/her private key/seed for some reason or to download a fake wallet.

The story can go something like this :

- Hacker: I found some vulnerability in Electrum, you may lose your coins if you do not update to a new version.
- Victim: What should I do now?
- Hacker: You need to download a new wallet from this link: electrum.xxx or send me your seed to check it.

Depending on how naive one is, in some cases, a hacker will manage to trick a few people with this story. Not so long time ago someone is posting some seed checker tool for Ledger HW on Reddit, and some users lost their coins by typing their seeds in that tool, how stupid that can be...

How could possibly this be. While just chatting in facebook messenger and then he did lost his offline wallet. I may be getting the wrong idea but may be he lose his wallet because he let his whoever he whom is conversing with deceive him. It could definitely be a bait link in which your friend find useful. He may be have lack of awareness towards hacking stuff. Because there is no other way around he could protect his wallet other than not letting someone knew his keys. Never ever click a link in which it has something to with his wallet other than the link of the wallet itself, else is a trap.

  Something is definitely missing in your write up,  did your friend disclosed his private key to the person he is chatting with? Or did he write it in an open place that someone else can easily get access to,  To protect your offline wallet,  make sure that  u back up your private key in different places,  and avoid exposing it to anyone

[Meowth05]

I think an offline wallet is secure enough to store your coins as a matter of fact online wallet is more vulnerable in this kind of thing. I think the problem is in your friend because he might not store his key but even so, hackers will not have access to it as long as the drive is not connected in a computer hence it is impossible. For better security, avoid clicking some anonymous links because your computer might some malware that could breach your private info such as keypass.

If he lost his coins in an offline wallet, then chatting online is not connected on what happened, I guess he printed out his private key and someone stole it (maybe) or he accidentally put it on the garbage he throwed outside, then a certain person got curious about it and didn't waste the chance to steal those coins (lucky for that person) whoever got his coins.

That was odd because I am using also an offline wallet for years already but I didn't lost any of my coins, probably just a human error, in your friend's case.

E D I T: Please elaborate the situation, be more specific.
