Am I the only one who can't find the link?

It's always funny to see how articles and people need to justify what should be common sense. Arbitrage in ANY market exists, but is more difficult to take advantage of in reality. Outside of exclusive arbitrade and insider trading that we all know goes on with these centralised platforms (yes, Coinbase/GDAX, I'm looking at you), the arbitrage opportunities you and I can see are difficult to manage and still require trusting the intermediary in the other country.

Would I love to take advantage of arbitrage right now going on in Zimbabwe, Venezuela and Iran, where Bitcoin is in demand? Sure. Do I want to trust some guy over there to help me take advantage of prices? Sure. Do I want to badly? Not badly enough.
