The funny thing is the big bosses at the largest banks are feeling the heat and are feeling that their existence is definitely being threatened with extinction like you said. Jamie Dimon bashed bitcoin and cryptocurriencies swiftly, yet prematurely and without much thought. He has since walked back his comments about bitcoin being a fraud and I found it quite funny that a quick screenshot that went viral showed about 75 positions at JP Morgan Chase Bank actually have BLOCKCHAIN in their job title. Jamie Dimon and others will adopt it and embrace it or lose their business altogether. They have no choice and they know it.
