Which Linux distro would you recommend that has highest security possible and do you suggest dual booting or booting through pen drive? I am looking to purchase gaming laptop, and I'd require windows to play games of course but for crypto stuff, I'd prefer Linux.
I've been using Linux Ubuntu for everything for about 7 years. I don't use it to play games, because I don't play on the computer.
I use it on a computer with Windows (dualboot).
I once installed Linux Mint and didn't have a good experience. Another distro I've tried is Xubuntu.
Interesting new product was just released called Seedkeeper Ring and that can be used as a password manager.
It can also be used for storing encrypted seedphrases.

Interesting, is there any way I can export to another password manager (in case the software disappears)?
I don't know, probably Tails OS on USB stick is better option for privacy.
As for standard Linux OS you need to try them to see what fits you better, but for me Fedors is the best and most serious linux OS.
I forgot to mention Tails OS which is also great for privacy and offline wallets like electrum and sparrow.
