There's a great index of hacks here https://www.web3isgoinggreat.com/?theme=hack

It's breathtaking how frequent these are.

That’s like saying the $USD was hacked when a bank gets breached.

That's a silly assumption to make. I'm clearly talking about the poor security offered by cryptocurrency, in practice, as evidenced by the frequent hacks impacting cryptocurrency companies.

No. It's like saying that cash is risky when a bunch of cash gets stolen or lost.

Which it does. :D

Are banks breached at the same rate as bitcoin brokers? I think that was op’s point.

When a bank gets breached, there are mechanisms to make the victims whole, up to and including "Just print money; it's a fiat currency."

No such mechanisms in Bitcoin, so hacks have longer-term impact.
