i think it is not such a difficult job you can do it very simply, you can exchange bitcoin into your local currency in exchange and then can also buy bitcoin if you feel that it is the good time to do so.
Yes , but it has a risk behind them . Especially you sell it in online sites , who knows you would be get scammed or it's just fake sites to stealing your money . But , as long as you sell it in the right place and has a good reputation you should be fine .
if this is happen to me, i will sell it to my friends as local exchanger because he is a good person and have good reps among us and he always give a good service to us. i am not yet to exchange my bitcoin into exchanger in my country, but i only do it to my friends.
