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.
using 2 wallets is it not confusing for you? I myself only using one wallet from the beginning I joined and no problems until now. many people say do not put eggs in one container I think it's not a problem. You just have to make it safe
make authentication for your wallet ?
