Just like you should learn basic things like: "don't carry bars of gold around in public in dangerous neighborhoods and expect not to get robbed", you will need to learn basic skills around how to use and handle bitcoin with self custody.

If you don't, then you can only ever hold paper bitcoin which could be disasterous for you. Don't understand what paper Bitcoin is? Maybe that's the first thing you should study about bitcoin. 😄

Sounds like you haven't studied bitcoin yourself, which is why you don't have the answer to your own question.
