Digital Currency Take Over

I will not say that digital currency has taken over the normal regular currencies yet. However, there is no way that we can doubt this thing that the digital currencies are taking lead over the regular currencies in so many ways and that now the interest of the people is greatly changing in a way they are more interested in knowing about the crypto currencies and that they are also investing their money into different coins.
For me digital currency took over already as we can see bitcoin is being use more than fiat and people are using bitcoin worldwide global currency, it is my only dream to see digital system all over the world it will be possible if we see people using digital currency only because it is more beneficial, more easier, more profitable than fiat so regular currency is getting vanished because of bitcoin gradually.
