I haven't started yet, just brainstorming. I read a whole lot of articles citing advantages to using Tor over a VPN (as opposed to using a VPN over Tor, which is said to be harder to implement and not as effective), so it occurred to me that could be a good way to protect your private keys when you need to use them, but I wanted to know your opinions first.
If your main goal is to protect the private keys; just keep them on a device that is simply never (really, never never) connected to a network. It can be a computer booted off a Tails Linux USB drive, but also a hardware wallet. You can trade even on a phone if you wanted; just make sure to withdraw funds to a machine / device that is fully offline, then you're good.Privacy is another thing. But the topic is security; and there it's simplest and safest to have a dedicated device for holding your keys. No matter how paranoid you are, how many blockers, antiviruses, VPNs, etc. that you install; a dedicated device will be better.
If you want to go max level; ditch the 'device' entirely, and generate a secure offline 'paper' wallet using an offline machine and dice rolls & stamp the seed phrase into a piece of steel as well. It's easiest to protect private keys if they never leave the physical 'offline' world
