It means that fiat would finally reach its end. As for me, I think next decade would not be enough just yet for digital currencies to fully dominate, as most banks and people from around the world still prefer fiat more than Bitcoin, etc.
Yes, all of us are free to predict about Bitcoin and other cryptocurrencies. But for me, theyre just predictions. This world is unpredictable, as what I have said over and over again in my previous posts.
To see a world where paper currency is fully replaced in a decade's time is impossible, you might see that in the developed countries but you have to take into consideration the poorer nations and how on earth do you think that will happen on a global scale, it is an impossible dream to imagine that the entire world will transact digitally and it is not going to happen in a century. The bitcoin market is just ten years old and it will take more than a couple of decades to reach everyone let alone dreaming of having a world dominated by digital currency.
One more thing, becoming digital and becoming crypto based are entirely different view of point and it is an entirely different topic altogether.
