As far as adoption goes, Bitcoin follows a familiar pattern. Populous, first world countries in North America, Europe and Asia were first to catch Bitcoin fever, the first to establish exchanges and the first to begin restricting them as well. While early Bitcoin trading in these countries was largely boundless, allowing for things like margin trading and high leverage, as more of each country’s fiat money moved into Bitcoin, governments and central banks began to draw lines.
The market witnessed a pointed example of such “no more nonsense” regulation as recently as a few days ago in South Korea. Following China’s example, the country decided to limit ICOs and no-fee exchanges, which had until that point been an enormously speculative influence in the altcoin markets. However, no matter the increasing rate of adoption and regulation around the world, Bitcoin always manages to find its “Wild West” somewhere new.
