The nature of currency on my own perspectives, it has its specific character pertaining to digital currency because it's volatile and not regulated by government.
Unlike with fiat currency, authority and economic impact of a country depends on how the inflation works for them.
Cryptocurrency can be used in different ways, it can spend on goods and online payment and other spending needs. Also the most common experience that people usually do for it right now is online trading, it can be stocks or cryptocurrency.
