Decades ago, in my country it was illegal to hold dollar bills. Naturally, you couldn't have dollar bank accounts. What was done back then was to illegally keep bills inside bags, hidden, and pray god they weren't found because you would go to prison.

The alternative is not holding money yourself. Buy everything as soon as you can, and hoard physical goods, which is cumbersome, dangerous and inefficient. Bitcoin is an upgrade in all senses.
