2019 the year of Battle between cryptocurrencies and Fiat Currencies.
Who is the winner?
There will not have the winner right now because the cryptocurrency can not replace the fiat at this time. In the future, maybe Cryptocurrency replace Fiat but it need more time to this thing happens
Both of them will run according to their functions, and there are no winners, I think that fiat is still used by the community to meet their daily needs, and crypto is still used to trade in the crypto world itself and needs a process if it will be used as fiat.
