Bitcoin is digital currency revolutionizing the finance Industry which many predict to be the currency of the future.
If Bitcoin is Adopted what happen to ilerate population(stone age people)
That is great question. Most sadly must die to make place for young people that easier will adapt new knowledge.
So if they need to die, we need around 30-40 years time for next generation adopting it not in terms of 30% or with good education 35% but 80% and with good education 85%

Progress is best with new generations.
