You can move small amounts out at BTC ATMs in various countries, but they have a limit. Trying to liquidate $10k USD worth of BTC will take an exchange, a verifiable ID and a bank account (and they'll probably send you a tax form). Trying to liquidate $50k or more of BTC will require a pretty good relationship with a major exchange, and you'll likely be put on the audit list by your nations tax agency and federal crimes agency.
