This can be kind of weird but my country is acting like cryptocurrencies not existing at all so banks are you ignoring the fact of crypto in the world economy stage.

Right.Banks and bitcoin do perform different tasks so bitcoin should not be a threat to any bank because there is really no competition between them.Banks are focused on fiat currencies but i also believe that maybe in the future banks will also open their doors in accepting cryptocurrencies once it will be legalized in such countries.

yes, that's right, banks are afraid and worried if their roles are replaced by decentralized systems, even in Argentina there is the first bank to receive crypto transactions especially bitcoin.

and in reality, bitcoin gets a great response from the public, and dominates every payment and every transaction.

because of that, they always create FUD to make bitcoin weak.

why many people are always comparing bank and bitcoin, as we know that fiat and bitcoin si totally different so if you comparing fiat and bitcoin or the bank with bitcoin it don't has the similarity, so stop comparing bitcoin and fiat currencies

Perhaps in the distant future it will be so. Now Bitcoin is a way of investing. Very risky.

I think this is true because there is no alternative now (other than bitcoin) that can resist a banking monopoly.

No, this is completely untrue. Banks are not at all threatened by bitcoin, bitcoin is unable to replace banks, since it does not have the appropriate functions. Therefore, banks there is nothing to be afraid  of bitcoins and other decentralized crypto currency. Banks will exist in any state, since they have actually become a part of it, serving the country's economy and state structures.
Bankers of the Crypto-currency are partially deprived of profit due to some loss of their customers, but banks and the banking system have nothing to fear.

they are afraid unequivocally yes but it seems to me that banks will find a way to regulate crypto currency

I agree.I really never think that bitcoin would be a big threat to banks because in the first place,bitcoin and banks have different perspective.If given a chance that bitcoin will be legalized in the future,i think banks will open their doors to bitcoin investors and they will work hand in hand to make progress together.

As far as i know herein my country aren't issue between the bitcoin and bank
So far the relationship of the both currency is in good condition why i telling this bank herein my country
Aren't afraid to bitcoin as currency and not giving problem or threat
How i can convert my bitcoin into fiat if the banks is not accept bitcoin
