Managing crypto activities from Linux on a USB stick?

Hello everyone,

I'm about to wipe my PC to do a fresh install with Windows. It's my main PC so I do all sorts of daily things.

Now I was thinking that I may want to keep all my crypto stuff (Ledger Live, browser with my hot wallets, accessing CEXs) on a USB stick and just access it when needed.

Now the question: Any (beginner-friendly) Linux distros that you would recommend? Especially considering if the USB goes missing and can't be accessed by a third party.

Before that I was considering getting a separate laptop, but this may be a better solution.
