Why is this? If my computer gets stolen all anyone needs to do is crack my password and they get my coins. I want to remove any trace that Electrum was ever on my computer. Can somebody tell me how to do this please?
Anything online is prone to hacking, so what you need is a hardware wallet or an airgapped wallet, so your keys are permanently stored offline, and you do not have to download and reinstall wallet applications to send, receive or view your balance. You can simply see and do all that in your complementary online watch-only wallet if it is an airgapped set up and in your interface software wallet if it is a hardware wallet.
