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
Using a LINUX operating system is much preferable due to their security factors around it, with windows I'm not certain but somehow if you aren't security conscious enough there could be some compromise such that you may not be able to handle, basically i have the Linux preference and that ahs fueled my recommendation for you. cold storage been a thing that cannot be really compromised easily because of the fact that there is little to almost no internet connection on it is a more reason you should consider a security measure that will help in getting your asset very secured than it has ever been even before now.
For Linus 2gig may be too slow to run it maybe you should get something higher if you want to dedicate a separate system to that purpose, i feel that will be the best approach for this. these are my suggestions and taught tho you may choose to try something else if you don't feel comfortable to use this information if you feel they aren't true enough or do not suite your needs on this actually.
