This will happen in upcoming years when world will be in the hold of bitcoin everyone will be using it and getting blessing from it and it will control the world economy and I wish that day will be soon. And so that I can trade across the world and change my cash money into bitcoin to live an epic life.
First thing you have to understand is that bitcoin is limited and there is not enough coin for the world to get hold of it
and the blessings from it
You can still trade bitcoin across the world if you know about bitcoin and you can cash out through your local exchanges to fiat if you are not aware of it
. To live an epic life you need to have a couple of hundred bitcoins and i am sure you wont have those.
Bitcoin will be a major player in the economy in the near future.
