Adapting Bitcoin as a single unified world currency is very possible only that its adaptation time is lengthening as much as possible, in fact many people already see this asset as the replacement of this financial system that has been implemented for years.
Being prepared for a new united and globalized financial system is paramount, since it is the recurring reality that is being loaded every day that passes.
Bitcoin is already a fact, only the community will determine its future.
