I suggest you to use Electron wallet, as you can see everyone's here in thread replies are also suggesting this wallet because it is the most popular bitcoin wallet, also it is very easy and convenient to use without any hard wallet needed, But if you really need a secured and looking for a safest way to keep your coins, I suggest you to use a hardware wallet because it has a high level of security since it is not connected in the internet which we all know that the potential hacking attack is happens often if you're using an online wallet.
