Trust Wallet is good as well to saved your bitcoin investment, while creating the account, you need to saved the pass 12 phase of the wallet by writing down on your dairy including the password, should in case of future time, if your phone device been corrupt, or stolen, you can be able to recover your bitcoin digital assets back.
^This wallet was introduced by CZ the CEO of Binance.
This wallet is multi-functional and supports different blockchains, but if you really want to separate your BTC from your altcoins is better to choose Electrum wallet for BTC and TrustWallet for the altcoins. Both are open-source wallets that you can trust, as long as it is open-source we can assure that our fund is safe and we have control over our portfolio. However, if you have a budget, just go for the hardware wallet, this safest wallet for all, why? Because this wallet has a security feature itself that can protect your crypto.
Trust wallet is a non-custodial wallet but it is not an open-source wallet like Electrum or others. Currently, it's safe to use and I haven't had any problems using it with Trustwallet, but if it's just for storing bitcoins, Electrum is still the perfect choice.
@op, since you already have Electrum installed, feel free to use it, it's the best rated software wallet available today. Later, if you have more conditions, buy yourself a hardware wallet to ensure the safety of your bitcoins.
