There are many countries where bitcoin is not accepted legally, so how do you use bitcoin in that country? Usually if you raise the level of bitcoin use in that country then you may get into legal trouble.
So how do you use your earned bitcoin in that country.
Most of the time I sell bitcoin to local clients for fiat money. As my country doesn't allow bitcoin as legal currency, I'm not able to purchase something in my daily life. But I can use it to purchase different types of service which are outside of my country.
