You're going to need an external wallet that will exchange to fiat currency of your country, so for me I send any HBD or Hive I am cashing out to Hive-Engine, and exchange it for something like Litecoin. Then I send the Litecoin to Coinbase where I can exchange it for dollars. I would ask what the favorite exchange is among others in your country.
I would also recommend not powering down if you can help it, my strategy has been when I need cash to withdraw any liquid or second layer tokens but try and keep my HP untouched, since higher HP is beneficial long term to my ability to give a nice vote and earn.
