This are my way of protecting my coins/tokens because recently my wallet been hack and some of my holdings gone. First create two wallets one for your holding or banking then second wallet for transactions or some aidrops. And try to download meta mask this app can help you to prevent phising site. And lastly keep your password/private key on your own way try to hide it.
I am very sorry your wallet has been hacker. Terrible experience. I think having several wallets is a better idea. I will also try to download meta mask. I keep my password private but I do not feel secure.
