People will be hacked less when they stop believing everything they see and hear. Being your own bank also means being your own security department. Pay attention to what you do and use common sense to determine if something is good or fake. It's better to be paranoid and consider everything to be a scam (and never get scammed/hacked), than to believe in free money and online personalities that want to help you get rich. That's how you get scammed.

Crypto is only as safe as the person using it is cautious. If no one can access your private keys and seeds, you will be safe. Unless a different vulnerability is discovered or there is an inside job in case of closed-source software. If they can, your coins are gone unless you have additional measures to protect them like multisig setups or passphrases.
