I don't think that traditional money will die just like that. I think that people all over the world would be lost if that happens in the next 20 years. In a 100 years, this will probably happen.
Until then, blockchain tokens like Bitcoin will need to coexist with the traditional money. Is Bitcoin and money the future you asked? Most definitely in my opinion! Otherwise I wouldn't be here!
Hyperinflation happens very fast so you never know. There are many example where you can see that.
It does, but I still claim that the traditional money won't dissappear just like that. Older generation would never get used to only a digital currency. Do you know that in France still exist people that make all of the calculations from euros back to the francs? All of the prices are also shown in francs and in euros in stores.
Subsequently I think that the wave of the biggest change will be introduced by the banks and their private blockchains and private digital currencies!
