Is it institutions that cant hold btc but can own stocks? Why would any not institutional investors buy btc?

EDIT* buying bitcoin is already extremely easy. One app and a bank account. Sure there is a learning curve but that is same with anything. The power bitcoin gives the individual is self possession of monetary assets. If you’re buying it through an etf i feel you are missing out on arguably the most important selling point. You are buying a portion of someone else’s stack that they r keeping in their possession. Idk maybe im wrong. I understand people have different priorities.

*EDIT* the investing from retirement accounts makes sense. I guess i should clarify that i was never attacking the idea, i was just curious why and how people were using it

I have recently learned about address poisoning.

I have a hardware wallet and any send transaction is going to be verified on the hardware wallet.

How can I confirm my receive address (or change address for a send) generated by my desktop software is actually controlled by my private key and not a hack by a virus or other means?
