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.
In my opinion, the best option is to hold them until you decide to sell them for a specific profit.
There are options to trade with them on the stock exchanges no matter what country you live in, but in general this is a risky move and if you are not familiar with trading you risk more.
