I'm still using an old XP computer for cold storage and to to sign transactions prior to broadcast. Currently running full install of electrum-2.9.3 using chrome and it currently works great with no problems.
Just wondering how much longer electrum will run on XP and if it's time to set up a cold computer with Ubuntu or some other more modern OS?
It will depends if you computer gets damage you can be still use electrum even in old version since the newer version of electrum still not work in old OS like windows 7 and xp.
So your wallet will be still safe until your computer gets damaged.. just always save private keys and seeds for future recovery as backup..
As of now i am still using older version of electrum 2.7.1 and still working unlike the latest version..
