You can use Electrum wallet, Blue wallet, such wallets to store bitcoins. But since you are using a trust wallet you are not going wrong. If you can safely keep your wallet seed phrase then you can definitely use trust wallet. I myself have used electrum wallet and trust wallet as well. All are safe but you must keep the wallet keys very safe otherwise any wallet will not be safe for you to hold any investment.
It is wrong to keep your bitcoin in trust wallet. Trust wallet is a non custodial wallet, but it is a closed source wallet, and in closed source wallets you cannot verify the code and you cannot be sure of what is going on behind the scenes. You could do everything right in keeping your funds safe, but you can still end up losing it just because you use a closed source wallet, like it happened to Atomic wallet users.
