Blockchain as online (hot storage) and electrum as offline (cold storage). It has been many years now I use two wallets and there are no problems when used.
Do not store in a single bitcoin wallet.
But many people here do not in need of hot wallets as they are all aiming for long term investments with their bitcoin savings. So, just a desktop wallet would be safer for all of us. Still, we need to have multiple wallets for diversifying the risk of being hacked.
