I dont get it. Why not global now. Simple example. I go to Iraq now. I go online then I can access it. I can buy also or sell it. So it is global right? Globally online. You just need internet.
Yes we are still at low percentage of population in the world that use bitcoins. But, you are right about adoption. Sectors that do investment could also help advertising it for faster growth.
But the thing of Bitcoin is that the value of the Bitcoin have to be higher so we can do many things with it later and that is nice.
No one can predict or control the price of bitcoin, but the fact is it needs some more time to get recognition globally, it has not been used by majority of people yet.
