What I believe is that next bubble or "pump" will be higher than any other before, including the 2013 Bubble, when central banks and the world itself adopt Bitcoin it will be huge
If it goes exponential like end of 2013 we could be seeing >$7000.
But I don't believe a bubble will come of that proportion.
Banks won't adopt bitcoin. They will allow it and might build services around it but won't adopt it.
Bitcoin is like cash money and gold so yes in theory banks could use it.
Bitcoin has an added "feature" it can be stolen online.
