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 ?
as for me i use 2 wallet, the blockchain,info for spendable amount, and paper wallet for storing the high volume, i enable authentication on my wallet, to keep my account still safe,
until now i dont have any problem
