1. Use a hardware wallet. If you can't afford one, make sure your PC is clean and use an open source desktop wallet (e.g Electrum) that give you control over your private keys.
I can't believe how some people actually buy hardware wallets but save their seed on a .txt/word file
Why would that be risky? If there's no internet connection on a clean pc and put it into a usb-stick? One back-up and put them into a safe location.
What I was referring to are actually personal home computers and mobile phones, hence, chances are that they're connected to the internet most of the time. Also, I wouldn't hear complaints about these stuff on social media if the seeds we're actually backed up properly and securely.
