For me bitcoin doesn't have to succeed, it already did. The people made bitcoin and the banks got scared big time.
Now it is for them introducing a new scheme
I do not think banks should be scared of bitcoin. This is new business opportunity for them. They can continue banking with bitccoin besides fiat.
of course the banks will be wary of bitcoin. because bitcoin is potential to unseat fiat. so appropriate when the bank became fearful.
What is needed now if the actual people rallying behind Bitcoin, which I have a feeling would be generated if more people started to use Bitcoin and more news was spread around, in a positive light instead of the negative news recently.
