There is a saying in the crypto world . . . not your keys, not your bitcoins. If you entrust them to a broker, they ain’t yours anymore.
That derived from the true reality of such things. If the stuff is not within your border, it ain’t yours and anyone who has it can change their minds at any time.
Ask Chevron in Venezuela, or in Ecuador.
Not your keys, not your coins.
I assume you keep all your money under your mattress
