Compared to Fiat, we all know that cryptocurrency has a multi-function, as a means of payment, commodity trading, and investment tool. Of the many functions, we can use it according to our individual needs and passion. I always say that learn your potential, then maximize it with the opportunities that already exist.
Internet can not be erased in our technology these days, most of our daily works are dependent on the internet and this is a digital era in which internet plays a big role in the society, even if there is a big war that is coming, internet will remain and it could only be erased if the Government will literally destroyed all of the physical source of the Internet like the Satellites in the space.
Without internet is like without Electricity, the whole world would be blackout and everything will be slow and will disorderly misfunctions.
That is one important aspect. So I always say, there is no substitute between fiat and cryptocurrency, but complementary. That's all to help increase the ease for humans in living life and achieving economic targets.
