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
In short, I need complete guide towards the set up
2GB of RAM is too small to use even though it can still be used. My advice, delete all files that were previously installed on the PC. Leave everything for the intended storage.
For a wallet that you can control on your phone, use Electrum. There is a link provided on how to create a cold storage wallet on Electrum and I think it will be useful for you.
