Bitcoin have lots of potential however it don't gonna replace banks or paper moneys in near future for sure as lots of people are still there in the world who can't even use electronic payment systems and for them bitcoin will be really hard system to understand.
Yeah and especially older generation will never prefer to use bitcoins and will keep supporting and using banks for their financial transactions as they will find bitcoin very complicated method.
Another important note to add is that older people are losing trust in banks more and more, with as result that they save up everything cash in their homes. It's a dangerous development, but they trust Bitcoin even less due to the media.
