You might want to consider using Tails for a far easier setup.

Some software that you might use would probably not be open source. If you're using it for a single purpose only, then its probably quite possible to only install things that are open source on it. It really doesn't mean much if you don't verify it and compile yourself; there were plenty of instances where supply chain attacks compromised well known programs and installed their own backdoor into it. Whenever possible, minimize the applications that you're using on the computer.

Eavesdropping on your network is possible, whether you're using WiFi or not. Fact is, most sites uses TLS which really just negates the risk. If you want to protect your funds, just get an airgapped wallet or a hardware wallet. Maintaining security of any device that is connected to the internet is a tedious task.

I agree with @Welsh.

None of OS, devices or AVs can protect our crypto if we have unhealthy internet-surfing. Linux is better than Windows and that OS is less favourited by hackers but OS can not completely protect you.

Surfing the Internet, as you indicated above, can also be different. And here the browser and its settings are important. In a Linux system, it is difficult to download anything without administrator rights, but the most common clicks on various kinds of links are also dangerous. I agree that a hardware wallet is more reliable, and if you use your device for transactions, then surfing the Internet should be quite limited.

As long as it's my own flash drive and I know that it's free from any virus or malware, why would I stop connecting it if it's a personal use flash drive?

I agree about public networks/wifi. I don't connect to them with my device but if it's your personal or home wifi why wouldn't you connect?

Because there are a lot of windows users worldwide, many hackers are targeting them. But if you know how to protect yourself and you're very much aware how your PC becomes infected by their malware and phishing links, you only need to be a responsible pc user.

IMO avoiding Home's WiFi is too much, unless you let guest use it or you can't trust your family.


What's the point of removing drive letter? If you don't want windows and windows application access the drive, you better use drive encryption (such as LUKS).

Security, and vulnerability is significantly linked with how the user uses their system. Although, Linux is not only safer because of the way its been designed. Its safer because its much less of a target, than Windows. This is simply because the vast amount of population is using Windows as their primary operating system, there's also the correlation, that Linux tends to attract more advanced users, and not the users which are prime targets for malicious users.

Although, you could in fact increase your security ten fold, by either physically compartmentalizing or using software that virtually does it for you. I've talked about Qubes OS a few times, but it basically allows you to isolate different parts of your machine, so that if one is compromised, it won't all be compromised. The benefit here, other than the clear benefit of compartmentalizing is Qubes OS due to the way its designed, operates a little different from other virtualization software, and traditional operating systems, it means that there's much less malicious attacks out there that will compromise the system.

Physically compartmentalizing is the best approach, although its likely overkill for most people. Plus, it can be tedious. I've tried doing it physically, and depending on your needs it can be rather expensive if you need powerful machines for your activity. So, Qubes OS or another compartmentalizing operating system is the next best thing.

However, to return to your original point. Of course, Linux users can be attacked. Linux isn't impenetrable, but the security is definitely an improvement over Windows, and therefore your reducing your scope of error even if you are security conscious. 

Your post is good for Linux users. But agree that not everyone can handle it properly. I also prefer Linux systems, but they cannot be a guarantee of user safety. Moreover, the systems themselves must be correctly selected for their needs.
Recent news reports that a backdoor was discovered on Linux systems that went unnoticed by VT for three years.
Just read what he could control: https://blog.netlab.360.com/stealth_rotajakiro_backdoor_en/
Therefore, all manuals are, of course, useful, but all responsibility for their safety always rests on the shoulders of the user.
It is necessary not only to keep your devices clean but also to constantly monitor news about emerging viruses to take timely action to protect against them.

New device? Just reflashing the OS is enough which almost removes 99.999% from your device if there is any harm while you can still can be hacked or at potential of losing your privacy whenever you are connecting your device to internet, for example Google chrome the biggest spyware of this world but still everyone using it.

Just buying a hardware wallet is more reliable than maintaining a separate device for your crypto wallets for various reasons.
