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.
The feeling is mutual. In my country its not a big deal to sell bitcoin to cash because their has a wallet that we used to sell it into cash and we can also used it in remittance which is for me its very convenient to use. Its good to know that even if its not legal yet they still allowed us to used it and hopefully ot will continue and it will be better in the future.
In some countries there are no clear rules regarding the use of cryptocurrency. their government has not provided clear regulations for this. then you are still free to use bitcoin for anything, shop or exchange it for cash. Yeah I hope there are clear rules in forward for this
