I am living in Canada and its so great that Canada has been attracting digital money companies to invest. Bitmain, the world's largest Bitcoin operator, is considering moving its operating office to Canada. At the same time, Hydro Quebec (Canada) negotiates with about 30 Bitcoin operators on their migration plans. How about your countries?

I know that we must pay fee when we make a transaction but how much we must pay for a transaction?

I knew that there are a great many of people in my country use Bitcoin but I dont know whether Bitcoin is legal or not?

The first and biggest problem is that your Bitcoin mining process will be affected. 

You can use Bitcoin as a payment method for your online goods or services easily and quickly than your credit card

I think Trading and Investing are 2 best ways to earn Bitcoin but ofcourse you need to know well about Bitcoin and had experiences.
