Hey Ed, u should look into cold storage on hardware wallets, your BTC will be far more secure.
Trezor is apparently the only FLOSS (Free, Libre, and Open Source Software) one (though I haven’t researched it closely in a while), the other main ones are Ledger and KeepKey.
An alternative option is a offline SBC, or Single-board computer. (BeagleBone is an Open one, hardware and software unlike the Raspberry Pi) there are many pros and cons, you could keep some of your stash on different options in addition to the manual recovery options that come with all of them to reduce your risk surface even more.
If you do spend the BTC (eventually) you should invest it into a FULLY open Linux laptop or desktop and phone (meaning the hardware too) there’s ThinkPenguin and also Purism.
Purism is one company thats currently working on the first truly free (as in freedom/free speech) phone, your personal communications and overall privacy will be far more secure.
Linux is a lot more beginner and user-friendly these days as well (for instance Ubuntu and ElementaryOS, a linux flavor which looks and behaves similar to Apple’s MacOS) and has a lot of good replacements for Windows only software.
You can always keep your windows platform as a backup for the exceptions.
Keep up the great work!
