The banker was outspoken and i like his/her replies to you.

Firstly, most of those Bankers are not technologically oriented in this 21st century rather cling to the old time outdated technology without effect. Some of them are older than  my Mum and Dad but still yet work in the Bank with their 90's knowledge, those set of individuals will not and cannot comprehend the modern days TECH.

Secondly, Their clients (that is the customers) most at times will always like to see the Bankers with minor issues that borders on transaction problem or sometime network problems. Client in this regard will be the most difficult humans to handle if eventually Banks adopt bitcoin into the traditional system. Imagine when there is 3 confirmation on the blockchain and my grand pa saw 1 confirmation at first still waiting for the other confirmations to occur, believe me on this; that, he will call Satoshi phone number to lay his complain.

So how will they be able to handle such hand full of ignorant from the public if eventually the digital currency merge with the traditional system?
