every country has a policy about the future of crypto currencies. America may delete fiat currency and replace it with digital currency, but it is different from policies with other states. in my opinion, we still need fiat currency in our lives because not everyone uses crypto currencies. and not all countries legalize crypto currencies.
 

No, not completely, but it will brought many changes. Financial institutions, can either cooperate or compete by improving their services to cope up with the cryptocurrency exchanges and trades.

I think not, because fiat needs a bitcoin vice versa. Both would be perfect if it could work the same. Bitcoin has a new system that cannot be controlled by anyone. While fiat can conversion of currencies into the bitcoin State.

Yes, just like the crypto exchange site I know where the transaction speed is very fast. The payment fee of this site is one of the cheapest site of exchange I know.  You can even pay in online business, games or physical store a s the risk is very small. If financial institutions will not make any moves to cope up with it, then they will lose to these online exchanges.

Its impossible to happen dude, the world is full of many problems, they will not add to their work by changing the economic system
that they have built for hundreds of years, eliminating cash and fiat for crypto. it's too difficult to imagine

Most of the users have stated that the governments won't be that supportive to make change on the financial institutions. From this people have a thought that legalizing cryptocurrencies will help with the change on financial institutions. This is completely wrong, the change begins with the technology adoption which doesn't need any form of legal measures. The financial institutions systems when integrated to blockchain technology automatically the use of cryptocurrency will emerge. To achieve this it takes a lot time as we've got very few number of financial service renders functioning on the blockchain platform.

removing fiat currencies is very impossible even though the crypto currency has grown rapidly and many digital currencies are legal. Fiat and digital currencies will support our economic activities. and fiat currency can be used in urgent situations without having to use technology.

I really doubt our fiat will be completely do away with, but am sure they will in gbe future be limited to local daily transactions and transactions that arr not very heavy. Cryptocurrencies will be use across borders and inter-states within country. To achieve a truely cashless society wherein transaction failure rate is kept almost at zero, we need the digital currency. We really can't continue with the gangster like style by which these economic cartels manipulate money to their advantage.
