Bitcoin has already sharpened the way most people view and understand world money; they can now differentiate between the way it could be used and how it shouldn't, when you need privacy, which currency you should go for, and when you need total control, which currency you should hold.
 
What I have learned to understand is that Bitcoin now has a place in the financial sector, and it's not there to replace any currency; rather, it's there to be used by those who want to use it, just as local currency usage can't be eliminated; there is always a need for it.
