Before I was involved with crypto, I was very careless with my devices.

I often just click on links without even being sure what was in it. If I needed to see it, I have to click on it immediately. I would also connect to public wi-fi not caring about the consequences it would bring. Now, I try to be more careful and thoughtful of what goes in and out of my phone, who is allowed to have access on my phone among other things..

I don’t even have my wallet on my laptop because I believe that it is more easier to get hacked on a laptop than it is on a mobile device. This is because on mobile device, we spend more times with apps, and i am always certain about what app i have. But on windows, a malware can come from chrome, and that’s even where metamask and the average wallets gets connected. You may not know when you get redirected to the wrong site and won’t notice anything wrong, until someday when your balance is empty. Thought I have a software that protects my laptop really well, I don’t risk it.

When it comes to mobile apps, at least with the iPhone. Each app is sandbox from another. Meaning that unless you give permission, one app cannot access the data from another app. This is why mobile phones are generally more secure compared to say someone using Windows and running executables from the shady websites.

Also phones can only run signed code. So the app needs to be approved and signed by apple for you to run it. Hence why it’s again much stronger security compared to a windows Pc.

You have made a good point.

Also we are talking about bitcoin here. You need to be above average to be able to successfully secure your coins. So when he says linux is complicated and it is for smart people while windows is for dumb people, he also admits that 99% of the population is dumb and will never successfully secure their coins.

If people insist on not learning about linux and other security practices, then somebody smarter and evil will take advantage of their stupidity. In this age not learning about linux is a choice between being stupid and smart.

On some rare occasions though, even being smart cannot help you. Even the bitcoin dev LukeDashJr got hacked and lost his coins to a thief in the past when you think about it. Sometimes we are just careless.

Not to have even the most basic computer security like antivirus and browser protection, VPN, etc seems pretty crazy to me.

You want to avoid public wifi as much as possible but it is not always possible if you need to do some work or access the internet while traveling,
that is what VPN is for so hackers can't steal your data. If you use wifi at home or share wifi with others at home I would consider using VPN for that also.

Maybe they find it to hassle for not using their device since not everyone have capabilities to buy multiple devices just to secure their assets.

But the least they can do is not to click any random links and don't use their main wallet to connect on platforms or anything questionable for them to avoid getting compromise we know to many schemes has been done by those criminals and we need to be more careful and knowledgeable on to good to be true schemes to avoid getting take advantage by those people who are greedy to do anything just to get easy money for theirselves.

To many good suggestion above so for its up for people to be knowledgeable individual to avoid this hackings and exploitation.

Sometimes people click on links by mistake that appear perfectly legitimate but turns out to be a fake website that installs very dangerous viruses and malware.
Security software such as Malwarebytes browser extension will block you from visiting such websites.

If you type in a URL of a well-known legitimate website, but mistype it by one letter you could be directed to a fake website that looks exactly like the real thing.
That is how people accidentally download malware, viruses, keyloggers that can record all your keystrokes, etc that steals your personal and financial information including your passwords.
That could lead to catastrophe for you. In such a situation a hardware wallet alone will not save you. It doesn't matter if you have Linux or whatever operating system you are screwed.

Unless you are a robot that never makes a mistake and never makes a typo it is foolish to believe that you are perfect and will never make a simple human error.

There is not really much to learn, installing one of the many Linux distributions is more simple than installing Windows these days, as all the drivers and most common applications are installed by default when you install the OS, and even if it was true that decades ago you needed to use the terminal for almost everything, this is not true anymore, and you can install, remove and use the majority of the software through a GUI, which most users should be extremely familiar with already.

I think Linux has the reputation of something that is used only by developers and hard-core tech geeks. That is why few non-tech people will touch it or even know what it is.

To learn a whole new operating system that is not very well known to the mainstream is daunting for most people. That is because everyone grew up learning computers on Mac and Windows since  those are the only two operating systems that are widely used in the education system. For better or worse Windows and Mac have a suffocating monopoly in the education system. Since virtually every child learned to use a computer through Mac or Windows it is just easier to keep using what you are familiar with as you grow older. They also have a monopoly in retail because 99% of computers sold are preloaded with Mac or Windows so you would have to go out of your way to even find a Linux computer to buy.

When you walk into any computer retailer all you see are Windows and Mac products on display for you to see and try out.
It is hard for Linux to be competitive when no one can even see or touch your product before buying it.

Let's look at reality and evaluate what's going on. If Linux is really so easy to use and so good, why do the majority of computers in the world use Windows and Mac? We even have to spend money to buy the other two operating systems, while Linux is completely free.

Also, if we use Linux, is there a guarantee that our bitcoins will never be stolen or attacked by hackers? What percentage is guaranteed that using Linux will never be attacked by hackers? Don't worry too much about the computer factors we use, what operating system, what brand of computer, the most important thing is how we use it.
