It would be a difficult thing to do because you're going to need someone to be in the other country to sell the bitcoin for you and that takes a lot of trust to do especially most of the people that do this have millions to start their business so it's not a waste of their time. I would say that it's a great avenue to make money but the expenses and the effort that you need to pull this off is going to be difficult and isn't this kind of thing been done before and the people that have done it got banned in the exchanges that they're doing their arbitrage trading?
