Technically you do not own bitcoin. Just the access.
While the broker is the registered owner of the stock I bought I am the beneficial owner. That's all I need. But you are free to own the stock in paper some companies might still give you that paper if you want to. I don't know why you would need that. This is more like a philosophical debate than a practical advise.
The actual point I am making: lots of stocks outperformed Bitcoin. There are laws built around that. You can't just be hacked and the stocks are stolen from you.
