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.

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

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

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.
