Nobody knows, but one thing that i have to say is that bitcoin and banks are gonna have a fight in the upcoming years, you dont have to be a clever to understand that. Banks makes money with fees, interests, and having people's money, and bitcoin does the same, only that you manage it and have the same features, and you dont pay fees. what could any person prefers? obviously bitcoin.
banks wont let people stop using their system to replace it for bitcoin, that is impossible, there is a lot of poverty around.
this thing scares me, but we will see, bitcoin is always going up, so bitcoin will never end.
