In my experience, it's typically been the opposite. Countries with harsher capital controls / make it harder to use Bitcoin, attract a premium in the purchase / sale of Bitcoin. South Africa for example has very strict capital controls, hence the price to buy or sell Bitcoin is higher than elsewhere. The catch is that you can't easily move fiat out of the South African economy, which makes abritrage, to take advantage of this imbalance, impossible.
