What is the status on the legality of bitcoin and crytpocurrency in your country? In my country, it is perfectly fine to do so. A local exchange wallet allows us bitcoin users to easily have our bitcoins exchanged into our local currency, and we may retrieve this through remittances or have it transferred directly to our bank accounts. I don't see anything wrong with selling your bitcoins for cash, unless the mere possession of bitcoin is considered to be illegal in your country.
