As far as Bitcoin is concerned it cannot be taken from you. They can ban access to exhanges, ban apps, ban all the ways you can use it, but they can never remove it from he Bitcoin network, it is still there on the public ledger as belonging to your address unless you willingly, accidentally, or negligently give them your private key. And keep in mind some people dont even write their private key down they just memorize it and thats the only place it can be accessed
