I'll be glad when there are many countries that use bitcoin. but I think distribution bitcoin is still relatively slow. in the local exchange in my country alone. there are reach 200k users only not reached 1 million. whereas my country, including big country. I think in time six years. the number of users will be 2 times more than this? many users will definitely give a nice effect for bitcoin
Nowadays I think that it's not only the restrictions on the many different countries but also the recent hack with could shake faith in bitcoin and people gradually can leave bitcoin because of the recent hack and the recent price drop which I consider dramatically, 2022 is not far from now and I think that bicoin until that time will be used by people but not exactly from everyone in the world.
Recent hack is nothing compare to Mt Gox saga. And that Mt Gox saga is more hurtful than the recent hack but still some people get hooked and put themselves in the world of cryptocurrency.
Bitcoin itself isn't the one to blame but those third party exchanges that greedy in making money.
