Electrum is not a cold wallet unless you use it on an airgapped device.
The wallet that I have used for altcoins which is open source is Unstoppable. You can use it on an airgapped device and have its watch-only wallet on an online device for transactions. The problem is that it is not support manysupporting some altcoins.
Or you can buy a hardware wallet like Trezor.
