Blackrock ETF. Not your keys, not your crypto.

Wondering how Blackrock is going to secure their (Our) crypto. They will have to be transparent about it, and they will need to grow a huge Cybersecurity team. There are a lot of people who are afraid of investing in Bitcoin because they're not technical enough to store their private keys. EFT could be a way out for them, but the same risk remains. What if Blackrock gets hacked? The more they own, the more they are going to paint themselves as a huge target. Imagine an EFT worth billions that would go to zero in an instant, that would be devastating to this space.
