They are going to adopt bitcoin for sure because like I said, it will eliminate their paper works. And thru the ledger, banks and their branches can easily share information seamlessly. It may take time to migrate their legacy system, but if it will improved their business and cost wise then I say they will go for it.
I do not agree with you that they are going to take
BTC for sure. Blockchain yes, it will simplify their work. But they will always be against
BTC, because they can not control it.
