I've been planning on switching to a cold storage format to keep my coins but I want it to be in a way of watch only wallet from my mobile where I can initiate my transactions . I'm currently thinking of using my old PC apart from the one I'm currently using, but I don't know how safe it is maybe I should just switch to Linux becaus it's windows , the Pc is around 2GB Ram I don't think I can upgrade that don't know if it will work for Linux or can I just use the Windows just that I've installed alot of games you know still so small to realise all those shit
I generally don't recommend doing this if you are a newbie and if you are not experienced in installing operating systems from scratch.
In case you have some basic knowledge that you can proceed with formatting hard drive and installing Linux OS like Debian, Fedora or Linux Mint.
After that it's easy to install Electrum wallet and remove all cards for internet connections from your laptop computer.
If you want easier and safer (for newbies) solution than I would recommend using open source hardware wallet instead.
