I can see based on my experienced banks dont trust cryptocurrency for now they dont know about it or maybe the employees only did not know but the bankers are all aware with it Im sure In my opinion cryptocurrencies need banks to convert digital money into fiat into seamless ways fast and convenient and vice versa they are slowly integrating blockchain into some bank systems and later on I think they will fully trust crypto and accept it.
Indeed, banks do not trust bitcoin for now, not just yet. Not only does bitcoin offers a great investing incentive but is also very risky in nature, and banks usually stay away from known risks as we all know them to be.
As a currency, banks will of course welcome any new player. But without government backing, it would be difficult for banks to extend trust to bitcoin. But yes, there is a growing interest with the technology behind it, and the news is out that banks are looking into practical applications of blockchain to the banking sector.
And surely, this will be progressive in nature should banks look at bitcoin in a collaborative way instead of competitive.
