If all of your money is being held by random companies, it's not really your money is it? Cryptocurrencies give you all the autonomy of cash, while still allowing you to send it to anyone over the internet.
That’s the very definition of “taken” isn’t it?

There you go, was that so hard?
Bitcoin isn’t some magical panacea, the reality is it’s as easily stolen/taken/lost in 99% of cases as anything else.
Sure, there might be some ultra tiny percentage of folks who are truly secure with it, but there is virtually the _same_ number who are ultra secure with other non-bitcoin stored value systems.
